Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you today. I do apologize that your question was not answered before. Different experts come online at various times; I just came online, read about your wee one’s situation, and wanted to help.

Now if she is targeting her tail base, the I agree that flea allergy dermatitis is very likely here. That said, it is important to know that treating for fleas is only part of the battle when addressing these situations. You need to also address the allergic irritation. Now if those bumps are flesh colored, they'll be part of the allergic reaction to the flea saliva from being bit. But if those bumps look like pimples, then she has a secondary bacterial infection of the skin that needs antibiotics from her vet to clear (if there are just a few, then salt water bathing them can help too).

As long as they are not pimples or in the meantime until you see her vet about an infection, you can try to reduce her irritation by treating with an antihistamine. Most commonly we use Benadryl/Diphenhydramine (More Info/Dose @ http://www.petplace.com/article/drug-library/library/over-the-counter/diphenhydramine-benadryl).A low dose (ie. 0.5-2 mg per pound of their body weight twice daily) can just be enough to reduce that allergic irritation. We like to keep the dose low, as it can cause drowsiness (just like people). And of course, this medication shouldn't be used if your wee one has any health issues or is on any other medication without speaking to your vet first. As well, using emollient shampoos (ie Episoothe, oat meal based) can also soothe the skin topically.

Overall, the area where she is chewing/licking is characteristic of flea allergy dermatitis. You were right to treat against fleas but also need to treat for the ongoing irritation from previous exposure. So, do consider the above for your lass. But if she is severely affected or we have pimples/pustules; then we'd want to also see her vet for antibiotics +/- a short course of steroids to nip this in the bud for her.

I hope this information is helpful.

If you need any additional information, do not hesitate to ask!

All the best,

Dr. B.
