Hello, I am new, I have a white mini schnauzer who just turned a year. I purchased advantage from Petco and I noticed Gingers fur became very oily. I tried to rub it off, but it did not work, so I decided to wash it off. The oiliness did not go away and after a few weeks the fur became brittle, coarse and yellowish. My vet said he thinks it will never grow back properly, but it may be able to be stripped. My groomer trimmed it shorter, but was worried it would not grow back if she cut it too short. I am not sure if there is anything I can do. Is it from the advantage, I have heard that since it is over the counter at Petco it is not the same as the stuff from the vet. I had put advantage from a different tube, but same package on my Jack Russell and his fur is fine. Did I ruin Ginger's fur forever? : ( Thank you for any advice.
