The scars don't show in person as clearly as the photo, so I didn't really register them until you mentioned it. I don't know what they're from, of course, since she just turned up here, but I'll ask the vet about that, too. She was so terrified of us at first and jumps at every sound that I'm afraid it was abuse. The ears are definitely flies, though. We had that problem with a couple of our pit bulls and it took a lot of trial and error before we found something that would keep the flies off. They'd be outside only for a short time and the blasted flies would have them eaten UP in no time. Thank goodness flies don't bother George's ears. We can buy this roll-on stuff at the farm supply store that repels the flies but doesn't bother the dog and you just draw a line around their ears with the roll-on. First you have to heal the existing sore, though, and that's what's the problem. The stuff I used to use on our other dogs doesn't seem to work on her, so back to the drawing board until the vet gets a look at her. He'll have a better idea, I'm sure.
Meanwhile, we haven't had any fights. Just a couple of times when George gets fed up with her, he'll sort of grumble at her, and that seems to do the trick. She's actually pretty obedient and when I say NO sharply, she usually stops whatever she's doing. George doesn't do Flat Basset as much as he used to, either. He wants to keep up. LOL I think they'll be good for each other. He'll calm her down and she'll stir him up.
