ALR22
New Born Pup
My 12 month old boy has just started getting a patch of thinning hair on his back. There is no sign of scratching or bleeding. They are kept very clean, changed twice a day (2 brothers together) and are the bestest friends. Not sure what to do. They are kept on shavings and have hay in their bed. It's just happened over the last 2 days. His brother is fine.
