Molly is 3 yrs old Beagle up to 3 week ago she was very active. Started yelping for no reason then would not jump up. About 2 week ago she started to have pain episodes lasting about 1 hour she becomes very distressed, pants and wanders about with tail tucked between her legs obviously in pain. once it is over she comes around. We have been to Vets 4/5 times she has had Blood Test and xrays all were clear. She has completed 2 courses of broad spectrum antibiotics. A couple of days ago she had 2 days pain free and was nearly back to normal. Woke up this morning and its started again. Any ideas because the Vet has no idea!! 5 hours ago - 4 days left to answer. Forget to mention that she won't bark as it seems to hurt. She has been neutered. She is eating and drinking normally and her bowels seem to be working ok too.
