My griff sheds minimally,,,probably would be less if I brushed her more than once a month but it must depend on the breeder's dogs because I've heard of some that have coats that shed and the hair has a tendency to matt. Mine dog's hair doesn't matt so in that regard she's very low maintenance. Super versatile dogs!
But if you decide on a griff be prepared to exercise the dog and get them off leash for at least an hour a day,,,more is better! And they like companionship,,,,not a dog to be left at home all day while their people are off at work. It's not fair to the dogs of this breed.

If you're not going to hunt the dog get one of the third generation doodles,,,,,supposedly they're non shedders. Portuguese water dogs don't shed either and they like the great outdoors.
