Q. My cairn is scratching and biting, has been allergic to chicken, on holistic /no chicken food. Any ideas?
A. The first cause in dogs and cats for itchiness is flea bites. Recheck what's the flea treatment is on and if is been done recently and if all ok other causes could be allergies (grass, dust, pollen...). Also skin infections can cause lot of itchiness. Every time your dog is scratching and biting please go to your vets will prescribe you the best treatment depending on the cause, the age of your pet etc
