At what age do dogs reach adult size?

Answer by  Roland27 (16334)

Most professionals agree that small breed dogs will continue to grow until about a year old when they finally taper off and seem to stop growing. As far as larger breeds go most say that they will continue to grow until a year and a half. They too will them taper off and stop growing.

It depends on what breed of dog you own. Though odds are if your dog is a year old, he won't get much bigger than he already is now, if he grows anymore at all. Though, some breeds of dogs can grow to be bigger than horses. You are just going to have to wait and see what happens.

Dogs reach their adult size by a year, although they will continue to 'fill out' for the next couple of years. Your dog probably won't get much taller, just heavier.

Generally speaking, a dog begins to reach his / her natural adult size somewhere between the ages of nine and sixteen months.
