Is he drinking enough water? Maybe add a little to his kibble.
He sounds like my Corgi, she shed constantly, but was easy to groom otherwise.

PS: About once a week give him a grooming outside, I used a thing called a shedding blade.
Anyway, a ton of hair would come out. I occasionally caught the birds carrying the fur away for nesting material. So, it went to good use.
