Re: Combing shepherds
I had the same problem with my chihuahua years ago and I brought him to vet, and the vet recommended HyLyt shampoo and bath oil coat conditioner, it worked.
Recently my gsd puppy got the same issue - doesn't shred a lot (yet) but got white flakes when I brushed him, and seems like he's scratching a lot due to his dry skin, so I bought the HyLyt shampoo and conditioner again. I used it once last week and I saw the improvment already.
It's much cheaper to get it online, pet stores have ripping price.
