have you moved recently, or has he had any changes? anything that could cause hime any stress? new smells, places, people, or things can cause an animals stress, and can result in hair loss or over excessive grooming.
both of my cats started loosing hair when we started packing to move, because of all the disorganization and changes they got stressed and there fore lost hair on their stomachs and parts of their legs.. their fur has been growing back a little bit now that their becoming used to the new house and new arrangments….
just a thought. i wonder if this is what caused hershey’s “bump” all the stress from moving and the change of living conditions…..
