My 75lb GS has, from what I can tell, ear infection. I did some research and found that there is this ear cleaning solution that can totally eliminate ear infection and clean it up. The problem is, won't let me squirt it in to his ears. He won't even let me get close to them. What I do first is I tire him out by throwing a ball for him until his totally out of it. This doesn't help anymore. I'm out of ideas, I have enough. He moves so much as if I'm cutting him and he started nibble at my hand. Any ideas?
