I have a three and a half year old mutt, who sheds excessive amounts of hair. My clothing and floors are covered with puffs of her hair, and I vacuum and use lint rollers daily.
I have tried fish oil, adding salmon to her diet, frequent grooming, bathing, using a furminator, and everything else I can think of. The vet tells me that my dog is perfectly healthy, so it's really just an inconvenience, not a disorder.
(If it matters, she's a mutt. Part hound. Here is a photo.)
How can I reduce or contain the shedding?
