"Mother Nature" tends to breed for sturdiness, intelligence, playfulness, ability to co-exist with other pets and people and longevity, so we can expect this puppy to be healthy and sturdy. His short haired coat indicates that he will not need weekly brushing and grooming. His loving family intends for him to live indoors, so keeping him clean shouldn't be any concern.
It's difficult to predict final size in a mix; a lot depends on the size and structure of the ancestors of your particular dog. Mixes of small dogs should result in smaller dogs, and mixes of larger dogs should result in larger offspring. The typical mixed-breed dog weighs around 40-60 pounds at full growth; however, the obvious Chihuahua in this puppy tells us that he will probably be quite small. It should be remembered that all "full-bred" dogs were once mixes of other breeds.
We are pleased to welcome this Puppy to our practice!
