Woody, approx 10 year old male was a stray for years and went in to rescue with all kinds of health issues....suppurating wounds to face and neck in part due to tomcat fights but also severe ear mite issues meaning he scratched himself. Woody also had ringworm, and was diabetic..now in remission. Since being with me he has improved in condition dramatically, but although his over grooming and scratching did improve, it has never gone away and seems to be worse again now. House is covered by Indorex, Woody has been kept up to date with flea spot on but I did use Advantage rather than Advocate last few times. Woody is currently on home made raw which includes chicken, pork, turkey and wild rabbit. I did attempt to keep him on solely the rabbit to see if it is a food allergy but it makes him very constipated, and there was not really a change in itching anyway. So......I want to try and establish whether this is a general or food allergy.Woody will of course go to the vet if necessary but I feel that a lot of this detective work can be done in the home before going down that route. I have a 'low chemical' home,no air fresheners, minimal cleaning fluids/washing powders etc. Woody can access the garden but rarely chooses to do so! Plan. make up duck based raw food for him for next week or so...this will include bone, but no offal/liver so not ideal long term. I cant guarantee that this is a truly novel protein, but it is a good start and at least easy to get whole birds with bone. use colloidal silver as ear drops twice per day, also Otodex Ear Drops Any further suggestions???
