A LOT of shedding can be mitigated by diet. I highly suggest “specialized” brands of kibble like Blue Buffalo. Our household has sworn by Blue Buffalo for almost 10 years. It turned my mother’s aging golden from a patchwork quilt of hotspots to a glorious, shiny full coat of golden goodness in less than a month after we switched him.
My wife’s aging dachshund had terribly dry and itchy skin. We switched her to Blue Buffalo senior for small breeds, and she had a fluffy, shiny red coat with not so much as a single itchy spot on her body.
My border collie/Aussie mix has been on Blue Buffalo since we got her home from the rescue. She was “fed” Science Diet, and it left her with a dull, constantly shedding coat. Six weeks on Blue Buffalo, and she had a soft, shiny coat.
Finally, both of our cats have been on Blue Buffalo since we brought them home from the rescue. When people meet them, the very first thing every last person has mentioned was how fluffy and shiny their coats are. They’re both completely black cats, and while we do get the occasional tumbleweeds when cleaning, they’re not much for shedding and hairballs are non-existent.
So I think it’s obvious we swear by Blue Buffalo. Your mileage may vary. I love their product. Very much worth the money. Also read the feeding instructions on your pet’s food. They may be overfed, and that can sometimes stress the body in such a way that shedding is more prolific.
Finally, and I can’t stress this enough, get rid of carpet. If you have a LOT of dogs (and/or cats), we highly recommend tile since it doesn’t scratch or wear as quickly as wood. Bare floors are much easier to clean, much easier to sanitize, and much easier to spot when you’ve got tumbleweeds or otherwise need to vacuum.
Good luck, and be patient. Remember if you do switch their kibble, gradually integrate the new kibble into the existing or you might cause digestive distress.
I just add tuna fish and sometimes a fried egg to the kibble.
