I would try diluting the conditioner and don't leave it on as long, and be sure to rinse it out completely. It may take a few baths to figure out what is best for his coat. Or skip the conditioner and see what happens without it.
Also if you're adding any types of oil to his diet, too much can end up showing up in the coat.
If he's still having problems, a vet check would be in order, as some skin conditions will give an oily appearance to the coat. |
