I have had good success with the derma 369. If she has a lot of skin problems then I would talk to your vet about writing a prescription for derma strength pro. This one is a little stronger but is a prescription. I hope this helps!

HI, thanks for using Boop by Petco! Poor Summer! Your Vet has tried a lot. My suggestion at this point is to see a dermatologist. I would have him on Nexgard or Bravecto to cover fleas, demodex and scabies despite the injections. I would start an omega 3 fish oil (see link). I would also do several seeks of an antibiotic and antiyeast. I would also use cytopoint. The dermatolgist can do skin testing as well for environmental allergies. You can try a thin layer of the quadriderm cream on the areas once daily but he can not lick it so you have to use an E-collar. It also will only help the symptoms you see not the underlying cause of his allergies. Do not use it for more than 1 week. I wish you the best https://www.drsfostersmith.com/product/prod_display.cfm?pcatid=19121

Thanks for using Boop by Petco! The concentration of chlorhexidine in that formulation tends to be higher than what we normally use in pets. You can use a veterinary [chlorhexidine shampoo](https://www.petco.com/shop/en/petcostore/product/septiderm-v-antiseptic-skin-care-bath-grooming-shampoo-for-dogs-cats-and-horses) which contains a more diluted version of the chlorhexidine. That could help with a secondary infection. The seborrhea sometimes can improve with supplemented fish oil. You can get a veterinary version of fish oil online or at your local pet store. Good luck and have a good one!

If there is a secondary bacterial infection, I would recommend using product called Duoxo Chlorhexidine + Calm shampoo and bathe twice weekly until resolved. I would also recommend picking up a hydrocortisone spray (Well and Good at Petco) and apply daily to the affected area to relieve inflammation. If it does not resolve or worsens, I would have a veterinarian take a look at Harley so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps!

It looks like it could be a contact allergy of some kind. You can try the following: 1. This topical steroid/antibiotic spray. Apply three times daily until the skin is back to normal. https://worldtails.securevetsource.com/itemView/view/198944_HomeDelivery.pml?productId=135244 2. Chlorpheniramine tablets (antihistamine). He can have 1-2 tablets by mouth every 8-12 hours. Will help with an allergic reaction. https://worldtails.securevetsource.com/itemView/view/198944_HomeDelivery.pml?productId=113389 Both are prescription items but I am happy to authorize them for you if you purchase them through the above think. Hope this helps. Best wishes.
