Re: Routine ear wash?
That's kind of funny how vets are about that. Mine has a sign in the exam room that says, "For your safety please allow the assistants to restrain your dog."
Several times a day after playing we go through a little drill that starts with Settle Down, Be Still, No biting, let me see your paws. (Yeah I know, I'm reminded of the Gary Larsen cartoon, What dogs actually hear. He probably hears, "Blah blah Down blah blah blah No blah blah blah.) But he seems to get the idea. Then I thoroughly inspect each paw, his tail, his belly, mouth, ears, eyes etc. He is not allowed to lick , play bite, or anything. He is to lay on his side and chill. It's a great way to calm him down and he seems to like it. If the vet would allow me to do that, I'm sure he would allow them to do it to him too. We've had no issues with the vet yet, he's been a perfect gentleman there so far, albeit only 3 visits for puppy shots. Other than the obvious part of seeing if anything is wrong, this drill is done pretty much solely for the times he might get hurt but vet's seem to ignore the training he might have had.
In their defense, I'm sure the vast majority of dogs they see have little training of any kind and a tussle can be expected with most of them. Your vet was doing the wise thing to stay away from her. If she had bowed up at him once, and she won, there's little to suggest that she would not do it again. This wasn't a training session.
As far as the ears go, I'm interested too. In my experience some ears can get so funky they will stink up a freshly washed dog. It permeates their whole head. Don't know much about the "flora" thing, maybe it's natural for them to stink a little. Almost all dogs do to some extent.
