My puppy is losing clumps of hair
My male lab will be 4 years in September 2002. Within the last month or so, he has started to lose clumps of hair on his back. These are big clumps of approximately 3 inches across and an inch wide. He seems to be scratching all of the time now too.
Do you have any idea what could be causing this?
Thanks
Rosemarie
