To predict your puppy's adult height, measure their height at 6 months of age. Then multiply this number by 100 and divide that answer by 75.In other words, puppies reach approximately 75% of their adult height by 6 months of age. Instead, look at the size of the litter in general, the more puppies there are in the litter, the healthier they will be. Puppies in litter 4 will be slightly larger at birth, but will mature to about the same size as their parents.
If they are about the same size, cubs generally end up around the size of their mother and males generally end up closer to the size of the male father. Large breed puppies generally reach full physical maturity at about the same time as medium breeds, with a growth spurt between 8 and 14 months. Mixed-breed puppies are adorable and unique, and there's nothing more exciting than adopting one of your own.
