Hi! We just adopted a 7 year old Yorkie from rescue and his hair is thinning just around his legs, stomach area... his history does show some allergy treatments and the vet just gave him an allergy shot on saturday (the day we got him). He was not sure if it was allergies or bad treatment since he was kept in a little cage all day laying in his own poop! how sad!

anyway - does anyone know if a vitamin or something will help.. or any ideas.. he has nice hair on his head and upper body (just a little brittle) help! Thanks!!!
