My dog is an outside dog(BlueHealer) and we have been having alot of rain lately. He started to get a soar on his nose and the he started to lose hair at the site of the soar. Next I started to see other little spots to show up on the rest of his nose, ears and hind legs. He is not scratching and it seems not to give him any discomfort. I took him to a Vet and he checked for mange and it didnt show up, also he checked for ring worm and it came up negitive also. But he stated to that the next test for ring worm would take up to 6 days and it has been 3 days so far.He gave my some antibactrial soap and Lymedip and some drops to put on his spots, and he has been on it for 3 days and it seems not to be working. I was wondering if it could something different or could be any other skin problems.
I would be patient and wait for the tests to come in. A rash like you descibe can be anything. It can be hard too narrow it down to one thing sometimes. If it persists and the tests are all negative I recommend a biopsy of the affected skin. vetcare
