does anyone know approximately what age a dog has pretty much reached its total height?

depending on the breed, generally small breeds mature at 2 yrs and large breeds closer to 3 yrs.
One thing to note though is that their growth spurts can vary so feasibly a dog can reach full growth earlier than they would mature. Some not til fully mature.

I think that most big dogs do not fully mature until the are 3 1/2 years old!

they say it depends on the breed.. but base on my observation on my dogs... they reached their total height around 2 years old.
