Why are my senior dog's itchy crusty bumps worsening after vets?

Question

"My 15 year old Maltese mix had one crusty small bump on her back. She was given a few rounds of antibiotic plus an antibiotic shot....finally just about went away and came back worse. Now she has about 6 of them in about 2 by 2 inch space. The itch is driving her crazy. I keep putting on the prescription powder and cortisone to relieve her. I've seen 3 vets now.... ". Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | spayed | 9 lbs

Hi and thank you for your post. There can be lost of causes for the crusty bumps and itchiness. If the veterinarians did not do a skin scraping, then this is what I would recommend be done. A skin scrape and impression smear of the area can diagnosis a bacterial infection, mite infection, or yeast infection. I would also recommend a fungal culture to rule out a fungal infection. I would also want to rule out a flea allergy if Betty is not on any flea preventative. Ruling everything else out above, it may be a food allergy or another environmental allergy such as pollen or grass, etc. An allergy test can help then determine what she is allergic to and therefore what she needs to avoid. There are certain medications out there to help with allergies in dogs. Antihistamines can help sometimes but there is also Atopica, Apoquel, and Cytopoint that work very well in controlling allergy symptoms in dogs. I hope this helps! Best of luck to you and Betty!
