I was a dog groomer before i had my babies. The best thing to do for a dog that is shedding like that is to get a good quality slicker brush and brush him whenever you have a spare moment. That way you remove the hair and it doesn't fall on the ground. Best advice I have. I had dogs come in every other day for a good brushing. These people paid 40 bucks for this a time and couldn't do without it cause it cut down on the hair so much. Most dogs I would just suggest shaving them but labs hair is so short and thin really that it never ever really seemed nec. If you need instruction or help I would be happy to help. Also, might want to suggest trying a better quality food if you are using a store brand one. Sometimes the more expensive brands help with hair quality and such.
