Hope everything goes well with the scan. I think its brill that you are so devoted to this pooch.
Earlier on someone mentioned serotonin levels in the brain, in connection with epilepsy medication. We have some mild issues with Molly and we were told to give her vit B6 with food and then carbohydrate half hour later, was told this would help with serotonin levels. Must admit was sceptical but a week later she was calmer. Anyone else had success with this. My vet said I was "mis-advised".
