could someone tell me what age a dog reachs there full height.thanks

Medium to large breeds reach their full height between 18 months and 2 years, not sure about smaller breeds.

Depends upon the breed, and even then, some lines within breeds mature earlier or later than others. We had one boy who was "finished" at 8 months and was winning adult groups in Open Shows from puppy classes. Another one, looked like a gangly kid until he was 2 yrs old. On average though, in our breed, I would say that maximum height is reached at around 12 months.

think she is a whippet cross. got from rescue home they where not sure.just curious as everyone keeps asking.
