My dog Sydney is losing the fur in tufts around her tail nd rear end as well as around her neck. I also have a 17 month old son who is always tormenting her. I am a tuft puller and the other day I filled a shopping bag with tufts, she is overweight, around 95lbs or so. Anyone have any ideas what the problem could be? I live in a small town, so the vet it almost 3 hours away. Let me know!
