Help! My 5 year old Bassett hound, Noodle, seems to be super uncomfortable and sometimes in pain. She walks totally fine but can’t seem to find a comfortable way to sleep. She winces and sniffs at her behind. I took her to the emergency vet and they said they couldn’t find anything wrong with her. Doesn’t appear to be worms and she walks and jogs fine. Only happens when she’s going to lie down. Can’t get her to the vet tonight and I’m worried.
