Why is my dog's head suddenly bald and hair not growing back?

Updated On September 23rd, 2025

My dog has a bold spot on his head and he didn't have it before so no hair has grown in that area since.

It could be that he suffered an injury in that spot, causing the hair loss. It can take weeks to months for fur to grow back in fully. It could also be due to a medical illness such as ringworm. It's always a good idea to have any hairless spots checked out by vet to determine if there is a medical problem causing it so it can be treated as needed.
