Predisone or any steriod is used for inflamation, sometimes skin allergies. I checked some vet medicine books yesterday but found none that said to use it for that. I have one Boxer on a low dose of dexamethasone .25mg a day, that is one of the mildest forms. She has a disc problem from being so wild. It helps her deal with the pain. She is nine and had little cat feet, just perfect but now they are splayed from the steriod, it relaxes the muscles. She also never cared about eating, now she is the first to wake me up for breakfast. I opted for that treament instead of major surgery which we would not know if it would help. She is just made to curtail some of her wild activity and seems to help. Just feed a good diet and I use Select vitamins.
