When I had three dogs, the hair from the yellow Lab and Lab/Beagle wasn't bad, but when Gus came into the house, it got ridiculous. We tried several different models and towards the end of the older dog's lives, we got the Shark and it worked pretty well, but brushing Gus constantly was the best solution. My mother went to a lot of doctor's appointments and I would bring a brush and a comb and a bag to put it in, and let Gus stick his head out the window and I would brush him and the amount of hair from a fairly short haired dog was amazing, especially in the spring and fall, when he would blow his coat. One time, mom was in the doctor for 2 hours plus, and I spent most of the time brushing him out. The wind was blowing and the pillow sized mound ended up blowing out of the car and getting stuck to the fence on the side of the parking lot. For almost 2 years, it stayed there, fading as time went by to light blonde, and we would drive over there across town just to see if it was still there or not. I never saw a dog with a great coat like Gus always had shed like he did. After he died, I found his hair in boxes radios, amps for years. We could always tell his hair because each hair was 3 colors and even though he appears to be Golden Retriever colored, if you cut the tips off he was light blonde, and if you went down further the hair would be almost black. If you look at the blonde patch on the pic along the collar, he had recently had a cyst removed a couple weeks earlier. In a couple more weeks, it would be the same color as most of the rest of him. Under all that hair was a brindle pigment pattern.
