I am so frustrated and worried about our newest addition to our pack. We adopted a hound mix, Ellie, from a shelter about 4 months ago. Within a week we noticed a raging skin infection on her lower belly. Her skin was also very pink on her belly. After several trips to the vet, and three different antibiotics, the vet did a skin biopsy and sent it to Cornell Vet School. The results were that she had atypical demodectic mange and a secondary MRSA skin infection. The dermatologist at Cornell cultured the bacteria and found that it was not resistant to clindamycin, and a couple of other antibiotics.

She as been on clindamycin, and daily doses of ivermectin 1% at 0.6ml orally (she is 50 pounds) for about 3 weeks. In the last couple of days, her belly has become very pink again, and the infection is returning. She has a bunch of pimples on her lower belly. I can't understand how she could still have this infection after three weeks on the antibiotic the vet said would work. There are two other antibiotics the vet said would work, but one has GI side effects, and the other cannot be touched for some reason.

I know it is important to make sure she has good nutrition. We have her on Premium Edge and give her an occasional dog vitamin supplement.

Does anyone know how long it takes for the ivermectin to start working? Any thoughts on why the infection would return after three weeks on the antibiotics?

Thanks, I called the vet today. She said I need to give the clindamycin and ivermectin more time to work. She gave me another three weeks worth of clindamycin.

I think the symptoms of the demodex are the pink skin. She also has a few spots of thinning fur. but no bald spots. The vet called the demodex "atypical", and I don't know what makes it atypical. I have searched for "atypical demodex" and have not been able to find anything. I think by "atypical" she was just covering for the fact that she missed the diagnosis for several visits, but it could mean that it doesn't present the usual symptoms.

Her food has probiotics added to it, but do you think I should give her more? Where do I get those?
