When buying a dog, a person does not always think about what breed is a puppy. But sometimes the owners convince them to buy the baby, because they need to sell it. It can be very difficult to find out the breed of a dog. Some breeds are very similar to one another, but mestizos can have similarities between the two. If the puppy is not purebred, even an experienced dog breeder will not be able to help you, but it is still worth a try.
Buy books that have photographs and descriptions of the breeds. Try to find a dog similar to yours. If you haven't found such a photo, don't despair. Try a broader internet search. When comparing your dog and pictures, remember that they may differ in color, because not always representatives of one of the breeds have a certain color.
You can take your pet for a walk in large parks, where other dog breeders also walk their animals. Talk to them, maybe they know what kind of breed your dog has. But if they begin to assure you that she does not have a breed, it is not a fact that they are right. And is the breed and pedigree so important, because you love the animal, probably not for this.
If the desire to learn the breed still persists, go to the dog handler or veterinarian. Surely an experienced person who has been dealing with dogs and their breeding for several years can identify the breed. You can also try to clarify with a veterinarian, but the doctor can not always tell with accuracy about the breed of an animal.
