My dog is losing fur on her legs and other parts of her body.

Customer Question

My dog is losing fur on her legs and other parts of her body. She had fleas but took comfortis and Benadryl. How can I stop this. I had previously put hydrogen peroxide on her fur to stop itching when she had fleas. She also has dry skin patches

I'm sorry that your question wasn't answered in a timely manner and I regret that I can't correspond with customers outside of this venue. You appear to be describing a flea saliva allergy which is usually poorly responsive to antihistamines such as Benadryl but quite responsive to prescription corticosteroids such as prednisone which are available through Molly's vet. The dry skin patches may simply be excoriated skin in different stages of healing but may also represent secondary bacterial infection commonly seen in association with allergic dermatitis in dogs. Molly's vet can also prescribe a systemic antibiotic in the cephalosporin class such as cephalexin or cefadroxil which would nicely address such an infection. Bathing Molly in an antibacterial shampoo containing either chlorhexidine or benzoyl peroxide should hasten resolution of such an infection and help remove the scale on those dry skin patches. These shampoos can be found over the counter and at Molly's vet hospital. Make sure that you continue the Comfortis and consider treating your premises with an over the counter premise spray such as Siphotrol which contains an insect growth regulator (IGR) such as methoprene. The IGRs don't allow flea eggs or larvae to develop into adult fleas and so break up the life cycle of the flea. Please respond with further questions or concerns if you wish.
