Hi. My 30 days old male lab puppy suddenly lost some hair on the fore head yesterday. It is like a big bald spot. Did deworming today and 7 in one vaccine. Is there any problem? Will hair grow in that area again ? Pic url below. https://ibb.co/HrR6hn9
Hello, your pup is really too young to be away from its litter and it’s Mum. A skin condition like this could be due to any number of reasons. You really need to get urgent veterinary advice. I hope he recovers soon.
