At 13 months of age, Yoda may grow just a bit more, but he is mostly done growing. Some dogs are just smaller in stature than others, regardless of having the same genetic background. It is unusual that Yoda (being a male) is smaller than his sister, but genes can do crazy things. Sixty pounds of muscle is still a pretty big dog! :-)

My Pitbull puppy isn't growing. Is he too small for his age?

Chico is such a handsome boy! He looks like a Pitbull and males can be around 35-60 pounds when fully grown. He still has a bit of growing to do, and he may be mixed with another breed of dog leading to his smaller size. Plus he is the runt, so they do tend to be smaller. I hope this helps!

My puppy is growing fast and getting big. Is this normal for his age?

Zeus is a puppy, and he's going to continue to grow during the first year of his life. The good news is that his growth will slow down. Fully grown, Zeus can weight up to 66 pounds, and at around five months of age, he should be getting close to 3/4s of his full grown weight. The only thing you can do is keep feeding him puppy food according to the package instructions, and make sure he exercises for 25 minutes a day twice a day :-)

Is my 11-month-old Maltese Schnauzer mix done growing at 10 lbs?

Thank you for submitting your question regarding Sam. He is likely full grown or very nearly at his age. He may fill out a bit more, but I suspect his weight or measurements will not change much. He can transition to adult food or do so within the next month. I hope this information helps!

How big will my 7-month-old 42lb rescued hound mix puppy get?

Atlas is a very handsome boy, congrats on your new dog! At seven months old, he will be getting close to his full size, and while he will grow some more (dogs typically reach adult size between one year to 18 months of age), he won't double in size from where he is currently. I would expect a little more growth from him but not a massive change in size or weight :-)

Will my 10-month-old mixed breed dog continue to grow much bigger?

Based on the mix of breeds you said I would suspect that Gracie has done the majority of her growth already. You might see some very small amounts of growth until 18 months of age but for the most part she will hopefully remain that size forever.

Why isn't my 3-year-old dog growing? When do dogs stop growing?

Their height is usually complete between 9-12 months with the exception of giant breeds which go out a little longer. From there they can fill out and get broader across the chest until 18-24 months depending on breed and sex. At 4 years old they are done growing unless they get over weight
