I have 2 Devon girls from the same breeder but they are not related My youngest one, Bella is 8 months old. She has less hair than my 13 month old girl, sookie. Bella developed a rash almost overnight on her stomach and chest mostly. I have had a biopsy done on her and it has a technical name but is like dermatitis. I have changed her diet to fresh roo meat and royal canin sensitive. I use cortisone cream on it which helps clear it, but it never fully goes. My vet says they can do allergy testing on her but that does a long time. Any help anyone could give would really be appreciated. As it completly changes her personality and I can tell it causes her distress. Thanks sue.
