If your dog is not currently on any medication for fleas, this is the first thing I would recommend - chewing at the tail, in particular, is very common for dogs with flea problems. If fleas are not the issue, then he may have some other skin problem causing burning and itching in this area, such as a seasonal allergy or a bacterial or fungal infection. Less commonly, chewing at the tail can also be a sign of a nerve problem like lumbosacral stenosis, or a stress-related compulsive behavior. I would recommend having Charlue examined by a vet to determine the problem and get him started on appropriate treatment - usually, antibiotics and steroids or anti-inflammatory drugs are needed to resolve this kind of problem.

It does look like he has rubbed his tail and caused irritation to the skin below. Fleas is a possibilty for this but I cannot rule out other allergens or tapeworms without seeing him. If he has fleas, then he may have a flea allergy- meaning he is allergic to the bite of the flea. I recommend taking him to the vet to check over his skin and get medications to combat the allergy. Also pick up a flea prevention from the vet- not all preventions are the same and flea collars don't work. You need to treat all the pets in the home and treat for a minimum of 3 months in a row. Good luck!

He could have allergies or his anal glands could be full. You should have your vet check his gland to see if they need to be expressed. It is common for dogs to chew at their tail when their glands are full. If not, you could ask your vet about putting him on an anti-histamine and/or a steroid to see if the problem resolves. If it resolves with treatment than he probably has allergies and may need to stay on an anti-histamine long term.

I recommend to have Tank examined. The yelping indicates pain which is unusual. The two most common causes of problems in that area are fleas or anal gland problems. Your vet will likely be able to shed some light quickly on the cause. Have him examined within the next 24 hours. Protect the area from any licking by having him wear an elizabethan collar at all times. I hope this helps.
