When it comes to purebred, you can look up dog’s size, personality, temperament and appearance ahead of time. The description usually matches purebreds. If you love surprises, than mixed breed is for you. Sizes and appearance are harder to predict. The same litter of puppies can be quite different in color, size and in the inheritance of their parents’ traits. Mixed puppies are usually unique as no 2 dogs are alike.
There are many debates, weather mixed breeds are healthier/better. This is not so. The puppy may inherit some genetic imperfections from its parent, regardless of purebred or mixed. Some breeds have genetic illnesses. Mixing breeds is used as a tool to repair the genetic deficiencies. For example: Bichon poodles are prone to seizures. Mixing Bichon and Maltese, produces a higher chance of a seizure-free dog. Since mixed breeds come from at least 2 breeds, there is a chance they will not develop breed-specific disease. Doing some research before choosing a breed, will help you understand the complexity of each breed.
Once again, all dogs are amazing. I am yet to meet a dog I didn’t like. So this preference is entirely up to you. When you treat your dog like family, they will grow up to be gentle, playful and affectionate.
