Hi,
Our lab (male)was shedding so much and I noticed is skin was dark. I thought it was his thyroid and had it checked it was within normal range. I'd have it checked out anyway. My vet charged me $13.50 for the test. If ya think Berner hair is bad, have a crack at Lab hair. It's the worst. Try getting it out of fleece, or out of the material on the sofa he just walked by.lol As least Berner hair is like tumble weeds.lol Good luck with your dog. Jennifer
