I have a 7 year old female Rottweiler and I recently found out that she has an allergy to the cheaper brands of dog food. At least, this is what the vet told me. She prescribed some steroids and antibiotics, and Aisha(the dog) did seem to get better. I changed her food to something she's not allergic too, but now she's relapsed, so I wonder if it was an allergy at all. Her hair doesn't fall out, it's as if it's irritated and she's trying to rid her body of hair. She scratches an area 'til the hair is almost all gone and moves on to a different place. Her skin isn't red, isn't irritated except for where she's scratched too deeply. She has also lost about 15 pounds since the first time she got sick, but the vet said she doesn't have worms.
If anyone has suggestions to what the problem might be or what might sooth her so she won't scratch, please let me know. What I'm most worried about is how deeply she scratches. She has places where the draws blood and I'm worried about possible infection.
