Back in January (his prescription is dated the 6th) Max had a build up of black stuff in his left ear, so much that you could just see it if you flipped his ear over and weren't even looking closely. It was also red, and he was rubbing at it, which is what made me flip it and look at it. Since then I have been attempting to clean his ears, rather unsucessfully though, as he won't let me at him with any cleaner, cloth, or wipe. He does however let me clean it out with my finger, so i've just been doing that since it's the best I can do. The vet also gave him Animax which cleared it up in a few days. At that time he was eating Canidae, but he also got other foods as treats, along with other stuff like occasional cookies, liver treats, other types of treats, pieces of apples, carrots, just to name a few. Recently, I noticed he had the same build up as before in his right ear, so i've been cleaning that one out with my finger. He wouldn't let me use an ear wipe, or a tissue, and when I tried giving him liver treats while doing it, he'd eat the treat them come after the wipe to eat it. When I tried liquid cleaner on a cotton ball he ate that. There isn't as much build up as there was in the original occurence, but before the original time, his ears were totally free of build up, the first time his right ear was totally clean, and this time the left ear is totally clean, so for him I am assuming that none to minimal amounts of build up in the ears is his normal level. I am pretty sure this started for the second time while he was eating Canidae, but I have switched him to Evo. Since the switch, which was over a week ago, I have noticed no improvement, but he does eat other things as treats still, so the culprit could be in there. It was slightly red earlier tonight, but I think it was partially due to my bugging him to clean it. He hasn't been rubbing it at all either. I did start putting the Animax that was prescribed for him the last time in it earlier tonight, since I know if I take him back to the vet, she'll tell me to use that again, and clean his ears, if she will even see him again. Last time he was totally terrified, and I fear she will suggest sedating him and cleaning his ears, because it was a suggestion last time. I refuse to do that, first since it is not a permanent fix, and second it does not seem to bother him to the extent that I feel it is worth the trauma, stress, and risk it will cause him.
Do food allergies often manifest in ear problems, because I don't think i've seen that? If after treating it with the Animax again it comes back, i'm thinking of trying an elimination diet to see if it is a food problem. I think the culprit would most likely be something in his treats, but what could I use, other than liver treats, that would not compromise the validity of the test? I use the other foods because I prefer to offer a variety of treats, but is it still possible to offer a variety while attempting to find out if this is a food problem? Also, is there anything else that could be a likely cause of this?
