How to Tell if Your Dog is Full Grown ?

Both large and small breeds mature at different rates so it’s impossible to say precisely how old your pup will be before they reach adulthood. There are some general guidelines which you can use as an estimate but don’t panic if your dog does not fit into them perfectly! You can use the breed average growth rate or simply watch for these signs that usually come with maturity:

Read : When is a Dog Full Grown ?


By around 2 years of age all dogs should have their full set of permanent teeth . If your pooch loses more baby teeth without any new adult ones coming in, they are probably not fully grown yet .


Mature dogs will have shinier coats while pups still have dull, coarse hair . If your dog is shedding more or less than usual this can be an early sign that it’s growing up into either a furry adult or longhaired puppy!

Weight & Height

Large breeds grow very slowly and may gain weight faster but it’s not unusual for them to weigh the same as their full grown size at 6 months old. Smaller breeds such as Pomeranians tend to mature much sooner and may reach their full size by around 9 months of age .
