Hello, I have a 9 month old fawn pug. I recently noticed dark spots on
his fur, and thought it was just new winter coat, but on closer
examination, I found that in these areas the fur was thinning and that
the dark marks were actually on his skin. We brought him to the vet,
who checked with a light for fungus but showed only minor signs, as a
trial we used Sebolux shampoo for a week (4 washes). No significant
improve,ment, the vet is not sure what is causing this and we are now
scheduled for a skin biopsy and hopes that will shed some light. I am
posting this just in case someone else has gone through a similar
situation and may be able to provide some insight. Any info
appreciated,
