For the past week or so he's been reacting to something. The cartiledge inside both ears is fire engine red and hot! Also, when I separate the fur on the neck his skin is also really red. I thought it might be some chemicals the lawn service used to spray around the lake where we walk. Well, I've left him home one the walks for the past few days and it's no better. Some times it seems to calm down and then Boom, it flares. He's still eating and very playful but scratching his ears. I think they may have yeast but I don't think that's causing the red cartiledge?? I feed him Eagle Pack Duck & Oatmeal. This morning I got a bag of Eagle Pack Anchovy, Sardine & Salmon. My Husband thinks it must be food related. I;m beginning to think so to?? I also stopped using the Peanut toothpaste thinking maybe that is it but I've used the same toothpaste for about 1 year and I brush his teeth everynight?? THe last 3 nights I just used water??THere isn;t anything else?? I'm really stumped. Tonight I put Preparation H on his inside ear flaps to help calm things down. I will make an appt with the Vet for Friday. THat's the next day she is in. I don;'t care for the other vet. He is my baby and I;m worried about him Has anyone experienced this in the ears??
