Veterinary questions? Ask a Vet for Answers ASAP
Hi, Welcome to Just Answer. I'm Chris, a small animal Vet based in the UK. I am reviewing your question and will get back to you as soon as possible
Sorry to hear about your dogs discomfort with his rear end, certainly anal gland problems would be the first thing to rule out in addition to parasites such as fleas.
We are an online question and answer service, we cannot examine or treat animals, you would need to see a local veterinary practice for this. If you are on a low income you may be eligible for charity assistance, I would try contacting the PDSA initially.
I hope that helps? Please let me know if you need any further help or advice.
