And, I meant to say this the other day, but, problems in joint and bone growth won't necessarily be immediately visible if the dog is overworked. Know what I mean? Sure, if you see her limping, that's obviously a sign of something amiss. But, she may not limp, even if it's something that is detrimental to her development. Good grief, does that make sense? It's why I didn't post it earlier, cuz I didn't know how to word what I was trying to say.
