There are a number of reasons why animals can have one eye of one color and the second of another, but the term for the most likely cause is heterochromia.  It is more often than not to do with melanin. This is a pigment that is found almost everywhere in nature (spiders being a notable exception) and it dictates such things are skin and eye color.

Adopting a puppy is always a good thing, whether you do it from a shelter or from a breeder, but buying a puppy from a breeder has recently been frowned on by those who believe there are so many dogs up for adoption from shelters that no one should have to purchase a dog. While it is true that shelters are full of loveable dogs, there are still reasons why some people want or need to buy from a breeder such as those that use an adoption site like californiapuppiesforsale.com. The thing is, buying from a breeder really isn’t much different from getting a dog from a shelter. You’re adopting a new pet either way.

Special Needs

Not everyone can just go into a shelter and adopt the first dog that they connect with. Some people who really want to become dog owners have to have a specific type of dog for one reason or another. For instance, people who suffer from allergies usually can’t adopt a dog that sheds because they’re allergic to their dander. They need a dog that has a hypoallergenic coat and these dogs don’t come up for adoption through shelters very often, or if they do, they are adopted right away, especially if they are on the younger side.

Other people may need to adopt a specific breed of dog to train as a service dog. Not every breed is well-suited for this purpose and those that are don’t often find their way to shelters. Plus, it’s harder to train an older dog to become a service animal even if they have the temperament to learn how to be one. You might be able to find an already-trained dog at a breed-specific shelter, but there’s usually a reason why a dog is at a shelter in the first place, and that reason may not make it suitable for the important work that a service dog has to do.

Health

When you get a dog at a shelter, you probably aren’t going to know its health history, which can be important if you don’t have the financial means to take care of a dog with a lot of medical problems. While you don’t know for certain that any dog that you adopt won’t have health issues, you can better understand what you’re facing if you get a dog from a reputable breeder. You can choose to adopt a pet with medical needs knowing you’ll be able to afford the medical care. But with a shelter dog, you may not know that a dog has a hereditary medical problem that will arise as it ages. 

Certainly, every shelter dog is carefully examined by a veterinarian, but they can only tell you if the animal is currently healthy or not. They can’t really clue you in on a condition that is going to develop in the future. Whereas a breeder will know this information and be able to provide you with tips to keep the condition at bay or what to do when it does arise. Knowing the puppy’s parents is also a benefit that you’ll get from a breeder. If the parents are both healthy, you’ll feel better knowing your puppy is likely to be healthy too.

Conclusion

Don’t let shelter activists deter you from buying a puppy from a breeder if that’s what you want or need to do. Only you know what’s best for your family and after all, you’re still adopting a dog whether you do it through a shelter or a breeder. Just make sure you choose an experienced breeder with a good reputation to ensure your puppy is as healthy as possible.

If you’ve recently adopted a puppy from a shelter or a site like texaspuppiesforsale.com, you’re probably excited about taking it to a dog park. You might want to show off your new cute, furry friend or just want to ensure your puppy gets lots of exposure to strangers and other dogs. Whatever your reason is for taking your dog to a dog park, you’ll need to understand two main rules for any dog park. This will make sure the visit is enjoyable for you, your puppy, and everyone else who’s there at the same time.

Pick Up After Your Dog

This should go without saying, but when your dog does its business inside the dog park enclosure, be a good pet owner and pick it up. Most dog parks provide supplies for picking up your dog’s poop and disposing of it in a trash can. But you’d be surprised at the number of dog owners who conveniently “don’t see” their dog when they go number two in on the grounds. Perhaps they’re too engrossed in their phone or they’re busy talking to another dog owner, but whatever the excuse, there really is no excuse for not picking up after your dog.

The dog park is meant for everyone, so it’s everyone’s responsibility to keep it clean and poop-free. You would want other owners to pick up after their pets, so don’t be that owner who thinks the rules only apply to other people. If the dog park you go to doesn’t provide doggy doo bags, be sure to bring your own so that you can take responsibility for your dog’s mess.

Keep Your Dog in the Right Area

Most dog parks will have a written rule not to let dogs in or out of the enclosure so that owners can feel comfortable letting their dogs off leash inside the dog park. But one of the unwritten rules is to keep your dog in the right area for its size. You’ll usually find that dog parks have a separate area designed just for small dogs that keeps them away from the more energetic larger dogs. Even if you really think your dog would love to play on or with one of the structures in the small dog area, don’t bring your large breed dog into that section if small dogs are present.

The purpose of a dog park is to allow dogs of all sizes the opportunity to enjoy a yard-like environment without being on a leash and without the risk of other dogs hurting them. Although a large dog might not intend to hurt a smaller canine, it can happen accidentally, which is why most parks separate the two. If your large breed dog takes a while to warm up to other dogs, you might be able to use the small dog area to get it used to the idea of playing with other dogs, but be sure to ask any small dog owners first.

Conclusion

These rules are usually universal for all dog parks, but you should always check the specific regulations for any dog park you’re visiting before you bring your dog to the area. This will help you and your dog have a good experience at the park and other owners will welcome your return.

You’ve been looking at all the cute puppies available on Uptown Puppies and you’re really leaning toward adopting one. But is it the right time? There certainly are better times than others to add a four-legged friend to your family, but when are those times? Here’s a short guide that can help you decide whether or not a new puppy is in your future.

 Can You Provide What a Puppy Needs?

This is by far the number one thing you must consider before getting a puppy. Are you able to provide food, shelter, exercise, company, and medical attention for a dog? If the answer is no or maybe, it’s not the right time for you to adopt a dog. You have to be in a financial situation that allows you to pay for the things your dog will need to survive. Obviously, they have to eat and they need a place to live that’s safe and comfortable. But the less obvious needs such as exercise and company are just as important.

If you live in a small apartment that doesn’t have an easily accessible yard, you should not get a dog or at least a large dog that requires a lot of exercise and outdoor activity. If you work 12-hour days and the dog is going to be left alone for that time, you’re not ready to adopt a dog. Puppies are very social animals and need to be around their human owners often for them to have a happy life. If you can’t dedicate a large portion of your day to their well-being, it’s better not to have a dog for now.

Medical attention is another requirement for dogs, but especially puppies. You’ll need to pay for a wellness exam, vaccinations, and tests to make sure your pet is healthy and stays that way. Plus, if your puppy gets into something it shouldn’t, you may have unexpected veterinarian bills as well. Be sure you can afford these services because your dog is depending on you to take care of it.

Do You Have Time to Train a Puppy?

Adopting a puppy means you’re getting a dog that is basically a clean slate. While this is an opportunity for you to raise it the right way, it also means that you’re going to have to dedicate a significant chunk of time training it. If you work a lot or have upcoming travel plans, it might be better to wait to get a puppy until you’re going to be home for a while so you can help your puppy develop good habits.

Are Your Kids Old Enough?

We’ve all seen the darling photos of a toddler cuddling a puppy, but having a young child and a young dog at the same time isn’t always a good idea. Children need to be old enough to understand how to treat and handle the dog and you might also want them to be old enough to be able to take some responsibility for the dog. You don’t want to create a dangerous situation for either your children or the puppy.

Conclusion

If you can answer “yes” to all of these questions, then you’re probably ready to get a puppy. Make sure you research the different breeds so you’re sure to get the dog that fits perfectly into your lifestyle and if you’re not 100% sure you want a dog, wait until you are.

Very probably not, but it must be said that the mask worn by the brilliantly colored Paradise Tanger is more than a little reminiscent of the entire Green Lantern Corps.  This medium sized songbird is more than just a mask, however.  It has sky blue underparts and its upper body is a glossy black.  As for the tail – it can be either yellow and red or all red, depending on the species.

The bird is found in the Amazon Basin in South America, in over half a dozen countries there.  Such is the brilliance of the bird’s plumage that it is known locally as siete colores, which means seven colors.  There is no sexual dimorphism which means that the female, so often a dowdy color in other species, has the same magnificent plumage as the male.

As such it can be quite difficult to tell the genders apart.  The only thing which differentiates is that the male calls out more often than the female (whether or not you agree that that is extended to other species is entirely a matter of opinion).  Fortunately, the future of this species seems, for the moment, secure.  Although their exact number is not known, they are described as common throughout their extensive range.

The Paradise Tanager is a clean freak.  Each morning when the mist descends they awake before many other species of bird and ruffle and preen their feathers in order to keep them in tip top condition. Once a male has found a mate the pair elopes to the canopy of the rainforest.  This is because the higher they nest it becomes less likely that their eggs will be eaten by predators.  They chose a nesting spot and then the majority of each day is spent searching for nesting material, finding fruit to eat and hunting insects on the wing.

The species rarely lays more than two eggs at a time and another reason they nest in the canopy is because it puts them at a height where the humidity is just right for the eggs to develop.  After about two weeks the eggs will hatch.

A startlingly beautiful species, the Green Lantern may not, after all, have used them as an inspiration for his mask.  The Paradise Tanager is, however, a super bird in its own right.

Badlands National Park, in southwest South Dakota, United States preserves 242,756 acres (98,240 ha) of sharply eroded buttes, pinnacles, and spires blended with the largest protected mixed grass prairie in the United States. Bizarre and beautiful formations jut out of the fractured prairie in various shades of pink, red and yellow. Bison and bighorn sheep are a few of the parks multiple inhabitants.

Sit back and take in this glorious landscape with its wildlife through this short film created by Matt Brass.  The music is The Temperature of the Air on the Bow of the Kaleetan" by Chris Zabriskie.

The Hyrax may look like a guinea pig to the casual observer but looks can be very deceptive.  It has even been called the rock rabbit but its family tree is much stranger than you might expect. Its nearest living relatives are the elephant and, bizarrely, the sea cow.

You may have been lucky enough to have encountered a peacock or two in your time.  If you are like me then these beautiful, iridescent birds stop will stop you in your tracks.  Yet few people have seen one take to the air – and many assume that the three species are flightless.  Although the sheer mass of feathers precludes any avian marathon, they can and do take flight, normally to get to their chosen spot for the evening.  It may be a roof or a tree, but somewhere safe from most predators.

Nothing can quite prepare you for the exquisite sight of a hummingbird on the wing. Nature has truly spoiled us with this astonishing spectacle. Take a look as ten different species take flight in their search for food and marvel at the aerodynamics of one of the world's truly astonishing species.

It is found along the Pacific Coast from British Columbia to Arizona. Males perform remarkable display dives during the courtship season. The male, when his territory is threatened, rises up around a hundred feet before diving on to his rival. The dive is so fast it produces an “explosive squeak” as the wind rushes through the tail feathers.

Thought extinct thousands of years ago, the Mallorcan midwife toad was discovered alive and well in the 1970s.  Its lifecycle is astounding considering it lives among pools in the mountains of this Spanish island.  Oh and the male carries the eggs around his hind legs while they develop! This and other members of the living fossil club are featured in this fascinating documentary short by Rachel Ledbetter.

Hamsters – they’re adorable and surprisingly good company too. Here we take a look at some unexpectedly funny things you can do with hamsters when you’re bored – and throw in some cool facts about hamsters at the same time!

1. Amuse Him With Your Office Anecdotes
Hamsters love to hear what went on at the office. In fact they like nothing better than a long and intense monologue. Start with the time you got to work and give him a blow by blow account of the day’s activities. You can even tell him those secrets that you can’t tell anyone else, like who is having an affair with the boss. Hamsters love gossip!

It looks as if these snakes are dancing with each other, perhaps in courtship but this graceful exhibition is anything but friendly. Most frequently witnessed in the diamondback species this is ruthless combat: both rattlers are male and they are engaging each other for the right to mate.

Director Thaddeus D. Matula followed conservation biologist, amphibian specialist and nature photographer Robin Moore into the heart of the Costa Rican rain forest on the Osa Peninsula. The Osa is a mecca for biologists as it is home to 2.5% of all the world's unique species. Robin sets out to document some of its smallest four-legged inhabitants including the poison dart frog which has a very distinctive call! This amazing project was selected for the launch of BBC Earth.

You may just have done something of a double take. Yet these small creatures huddled together are indeed bats.  They are Honduran White Bats (Ectophylla alba) and they do not easily fall in to a number of bat stereotypes: they do not live in caves and they do not suck blood. Additionally their fur, as you can see, is snow white.

It is found only in a few Central American countries. If you are very, very lucky you might be able to find it in Nicaragua, Costa Rica and, of course, the country from which it gets its name, Honduras.

Yet it is extremely rare and, moreover, it is tiny – the largest examined have never exceeded 5cm in length. Not only that, but its white fur has evolved for a reason: camouflage. (Note: the above was caught by using mist nets in Costa Rica and was later released).

“There once was an ugly duckling,” goes the old song. This could not be truer of these stunning butterflies and their most peculiar caterpillars. Another opportunity to scratch your head at the vagaries of Mother Nature, take a look at this pictorial proof of butterfly beauty and caterpillar creepiness!

Monarch butterflies are renowned for their migration.  Yet no single monarch has ever completed the 2,000 mile round trip – it is generational in nature because of the sheer distance involved. There being safety in numbers this leads to what is surely one of nature’s most spectacular sights – that of millions of monarchs congregating together.

In North America the butterfly begins this massive yearly migration in August.  Monarch butterflies fuel up on nectar in the northern States and Canada - it is time to leave as the coming winter will be so cold it would inevitably kill them.  Unlike their great-grandparents they have never flown more than a few hundred meters in their lives but they head out over vast northern lakes with no hesitation.  This is the first leg of one of the world’s greatest migrations.

The chrysalis of the butterfly looks, close up, alien and perhaps even a little frightening.  Yet it is one of the four stages of the life of a butterfly and without these bizarre looking enclosures we would not have the beauty of butterflies.  There always has to be a beginning in this process and above you can see a Painted Lady caterpillar beginning the transformation.

The butterfly emerges two weeks later.  The abdomen is white and still inside the shell of the chrysalis. Various silk strands from the caterpillar stage are in the upper right corner of the picture. The colorful wings seen here at the top of the picture have yet to unfurl and harden.  The pupal stage (called chrysalis in the Lepidoptera) is only found in insects that can be described as holometabolous (a marvelous word if ever there was one).  This is a term which is applied to any insect group that undergoes a complete metamorphosis during the transition from embryo through larva, pupa and adult (sometimes known as imago).

If you were asked to think of a large mammal of the American prairie you might well say the bison, coyote or wolf, a measure of how much these species have settled in to our general consciousness. Yet there is one unique American animal which is less known but is perhaps the most charismatic of the Great Plains. Many refer to it as an antelope but that is far from the truth. A true American native, the Pronghorn has sojourned across the deserts and plains of North America for at least a million years: but an antelope it is not. Its closest relative is the giraffe.

The pronghorn is found nowhere else in the world except the interior western and central north of America. At first sight it certainly does resemble the antelope of the Old World but it is thought to be a classic example of convergent evolution. This is where species develop to inhabit at least two separate places in the world but which share features and behaviors which mean they may resemble each other despite no shared ancestry. To the untrained eye, their appearance would suggest that they are related species even when they are not.

Flamingos aside, you do not get to see the color pink in the animal kingdom a great deal.  A notable exception is the pink katydid.  Yet this is by no means a separate species – this coloring affects around one in 500.  You may have already guessed that the condition is something similar to albinism.

Known as erythrism, the condition causes a curious reddish pigmentation. It can affect the body of an insect as well as its skin, and it is so rare that it was not noticed by western scientists until 1887. The reason for this oversight was perhaps due to the inclination of the insect to remain perfectly still during daylight hours.

In 1989, Amanda Lollar discovered a bat dying on the sidewalk.  Distressed that any creature should have to expire in such a way she took it home to allow it a dignified send off.

However the bat, which she christened Sunshine, survived due to Amanda’s care and was the catalyst for Bat World Sanctuary, which Amanda founded in 1994.
