Why is my dog biting her sensitive tail, causing scabs, no fleas?

Question

My dog keeps biting her tail and now has scabs all over it, but she does not have fleas. It's very sensitive. What might cause this?

Debi Matlack · Accepted Answer

You may not find fleas, but a very sensitive animal can get a single bite that sets off the itch-scratch cycle. She could also be allergic to her food or treats, or could have been exposed to something in her environment that she's sensitive to, like a cleaner, laundry detergent, or carpet spray. It could even be a fungal or bacterial infection making her itch and chew. Your veterinarian can do an exam and some lab work to help narrow down the cause and get her started on a good treatment plan.
