Brown Flakes in an Irish Wheaten Terrier's Coat

Reader Question
We just noticed our Irish Wheaton has dried brown flakes through the fur on his back. We also noticed a couple of patches of the brown in a clump, which broke off into dried flakes when we brushed over it. What could this be? No sign of fleas. He is groomed every three months as his breed has sensitive skin.

Thank you


Answer from Our Team

Dry brown flakes and clumps along the back can be built-up scale and skin oil (seborrhea), dried discharge from a skin infection, or flea dirt. Flea dirt can be found even when you don't see fleas. Put some flakes on a damp white paper towel. If they turn reddish-brown, it's flea dirt.

Other possibilities include Cheyletiella mites (walking dandruff), which cause heavy scaling along the back, and yeast or bacterial infection under a dense coat. Wheaten Terriers can also have allergies that affect the skin.

Your vet can check with a flea comb, tape tests and cytology. Brushing between grooms helps you spot changes early.
