My dog Bailey (1981 - 1995) had bad allergies ever since she was about 3 years old. We went the route of testing and desensitization shots. Unfortunately ours did not help at all, but it was certainly worth the effort for the possibility that it would help. My Bailey was such a dear. She knew that after taking her shot she would get a treat and would come running when I called and told her it was time to take her shot. She would sit real still and couldn't have been a better patient. I guess I'm relating this to prepare you for the possibility that this might not help, but again, I still believe that one has to try anything that might help. It is heartwrenching to see them so uncomfortable all the time. Also this took place in 1985 or 1986 and hopefully there has also been some progress in the process since then.
