kitty I had an old border collie who started wandering and pacing the house, she would stand in a corner and look totally confused, seemed to have all the symptoms of dementia. My vet recommended changing her diet. She went on to Hills Prescription Diet, the b/d variety. (Assume it stands for Brain Diet). The change in her was very dramatic, she seemed much more alert, more content and to her, and my relief, the pacing stopped and she appeared happier. She went on to enjoy a few more years. Although this food is only available from a vet I do suggest that you make a few enquiries to your own vet and see what he/she has to say about it. It certainly worked for my old lady. Good luck
