So sorry to hear about all the troubles you're having with your dogs. It must be quite frustrating. Unfortunately, I don't have any suggestions for you. My dog seems to have quite different symptoms. Now that she's been on the prednisone for about two weeks, the symptoms have pretty much disappeared. She's on a low dosage which means not too many side effects. I got all nervous when someone on the message board mentioned how bad prednisone is for dogs but I did some more research and learned that the anti-inflammatory kind that she is on is not as detrimental as the other kind. Also, humans have very different and a lot more side effects to drugs than dogs do. The swelling I was expecting from the steriods doesn't occur in dogs. I hope to ween her off the meds soon. But, I'm afraid that her allergic airway disease might be with her for life. I wish I could treat her homeopathically. Anyone know of a animal homeopath in the Toronto area?
