What's the adult size and weight for my 5-month Maltese Shih Tzu mix?
Updated on September 23rd, 2025
Pet's info: Dog | Maltese | Male | neutered | 5 months and 2 days old | 5 lbs
I would like an educated guess on my pups adult size and weight. He is a Maltese mixed with Shih Tzu, currently 5 months and weighs at 6.2 pounds and around 11 inches tall at his shoulders

Unfortunately that's hard to know exactly because he is a mixed breed. Mixed dogs can some grow larger than either parent. In general, small breed puppies reach adult height around 6-8 months of age so I suspect (as a guess) he may only grown another inch or two.
He will gain weight and fill out until about 8-10 months of age. I suspect he may end up around 9-10lbs. This will depend though on which parent he takes after. Maltese tend to be light boned and thin where as Shih Tzu's tend to be heavier boned and have a stockier build.
Again, know this is all a guess. Sometimes puppies can be late bloomers. Your veterinarian can get a better idea based upon Comet's bone structure. I hope this helps.
