Since there are a lot of doggo moms and dads here, I have a question.

Cleo has developed really dry,flaky skin, to the point that clumps of hair are coming out with big skin flakes attached along with serious dandruff. She’s on a food for sensitive skin and tummies and we’ve had her on apoquel for the itching but is causes awful diarrhea, so we switched to Benadryl for now. Do any of you have experience with adding something like salmon oil or other supplements to help with this? She’s shedding ridiculous amounts, but she’s a GSD and that’s expected. I’ve ordered some probiotics for her sensitive tummy, but need something that would help her skin too. Thoughts? Suggestions?
