Mable, yu have a beautiful dog!

I have a husky mix so you can imagine the clumps that come out of him. he sheds just about year round but this time of year it is horrible. Count your blessings LOL
Anyways even any old shampoo will help loosen some of the hair, it just happens naturally between the wetness & scrubbing. I have tried a few different shampoos & sprays that are supposed to help but they really don't & the ones that do help only help a little & they need to be used often. I found that it is not really worth the time or money.

Brushing daily & vacuuming works the best. Oh & the right tools (brushes combs) help tremendously. If you are unsure of what tools may be better for your dog, just ask a groomer they will tell you. Good luck
