I have medium size dogs and a lot of fur comes with that bunch. I purchased this to help protect the seat and to keep them from sliding off the seat. I would say it works well. The loops do slide somewhat, but I just tighten them every so often. I like that the silky material means the hair shakes off easily. I admit I do use custom seat protectors under this as well, but then I have a brand new car and want to take care of it. This still does a good job of keeping most of the hair off the seat. With 3 dogs there is a lot of jostling back and forth, but so far the hammock is doing it's job.
