Unfortunately, distemper is a seriously debilitating disease and there is no cure. We can only try to limit the damage done by the virus. This often entails nerve and brain damage, and upper respiratory problems. The upper respiratory problems can often be alleviated, however the nerve damage is permanent. When it is mild, the dog can have a good quality of life. At this time supportive care is the only option and you will have to wait it out and see what damage will be permanent. It is a nasty disease, and I am very sorry your pup is affected.

    She is probably still recovering from the virus. Once you have Distemper, you have it for life, but we don't often see any signs of relapse until a little while later when it shows up as twitching or seizures. I would just allow her to rest and frequently offer her food and water. If she continues to be lethargic for 24 hours, then I would call the vet.
