hmmm! When we got our boy, he had a few very small bald spots, a few were a bit red and slightly scabby. We thought they were litter mates biting/playing sores. Then they started to spreeeaad! Soon his back,shoulders and a few on his sides. After skin scrapes and months of treatment with maleseb and a high gla shampoo, 3x weekly, it gradually started to go but he was very moth eaten for a while. When he moulted his puppy fur, we could see strange mottled markings on his skin!
We never knew what it was but it cleared after about 4/5 months
