well mine definitely did not stop growing at 7, 8 or 10 months... although i can't give you an exact age of when he did. i got him at about 24" and 60lbs @ 10 months. he's now 25" and 70lbs @ 3yrs. i'd say he's been this size since about 18months. no changes noticed since then except for his coat and color [tilden is also a long hair].
also, he was neutered at 10 months if that helps.
best guess would be to talk to you breeder and compare his heights to his parents.
