Common questions

Do paws show how big a puppy gets?

Only roughly. Weight at a known age is a better guide, and the parents' size is the best one.

When do puppies stop growing?

Small dogs around 9–10 months, medium 12 months, large 15–18 months and giant breeds 18–24 months.

Should large breed puppies eat special food?

Yes, a large-breed puppy food controls calcium and calories so bones grow at a healthy speed.
