Brodie is our 7 year old West Highland White Terrier. He has had no coat or skin problems until about a year ago. The problem is that his back gets extremely oily and he loses the undercoat. His back is also very sensitive to the touch and he tries to scratch it. Nothing had changed in the environment except one thing. Our daughter graduated from college and moved back into the house with her cat. We had never had a cat in the house. Can our dog have a cat allergy? We have another Westie as well and he doesn’t have any problems. Thanks! Sharon Conant Columbia, TN Yes, but westies are very allergy prone in general. They also respond to stress, household changes, seasonal issues, etc. Also can be allergic to people.
