When will my German Shepherd puppy be considered an adult dog? And when will he start acting more mature and non puppy like anymore? Just was wondering, and also when will his adult coat of hair come in?
Most large breed adult dogs are considered adults around 2 years of age. Depending on the pup, the adult coat can come in earlier or later than others. No set time frame but usually anywhere from 4-6 months of age, you'll start to notice a coat difference. GSD always have a puppy like mentality with their people. As for acting like an adult and less like a puppy, every dog is different.
