I have a 11 month old bichon frise. I have noticed over the past week he has been constantly licking and chewing his front paws. I have soaked and cleaned his paws with sensitive shampoo and just water. I have used sensitive baby wipes as well. I am constantly checking his paws for anything obvious that could be irritating him but cant find anything; no dirt, grass, stones or salts from the roads. In addition to this he is constantly scratching in his ears and they are starting to look a tad red and sore; again I cant see anything obvious. He's recently had the hair in his ears removed at the vets and hasn't touched them up until now. He's up to date on his parasite treatment so I don't think its mites. Also when in the garden he constantly rubs his head against the brickwork of the house. I understand that bichons can have an array of allergies and I was wondering if this was potentially one of them? he hasn't shown any signs of this before hence why I am questioning it. He's also showing slight behavioural changed which I have mentioned in another post. He has been castrated- approximately 3 weeks ago so I understand some changes are to be expected but he's become very quiet and subdued; he doesn't seem to running around at 100mph like he was up to a week ago. I don't know if it's related. Any help or advice would be appreciated.
