Puppies grow half their body weight about 4 to 5 months. This gives your Vet a good indication of how big they will be as an adult!
Dogs rely a lot on their sense of smell to find food, potential dangers, and friends, so needless to say they sniff a lot. Their noses are designed so smells can stay in their nose while air can move in and out of their lungs at the same time, which means they can breathe freely and still work out what that smell is!
Studies have shown that dogs can learn over 100 words and gestures, which puts their intelligence of us on a par with a two year old. However, dogs are much easier to train than a two year old! They’re used for all sorts of jobs, from military roles to assistance dogs.
