I said no because I have leather seats and I can just wipe it down. Brutus sits like a nice young man while in the car and Frankie travels in a crate in the back of my explorer. He was never taught car manners and no matter what I try, I can't break him of his craziness. I really think he is happier and more relaxed in his crate anyway. Now, if you asked about doggie slobber on the car windows, that would be another story.
Castor nowadays rides in the back in a safety crate and there is quite a lot of dog hair back there! So no hair on the seats but outside his crate, yes!
There is a commercial on TV for febreeze. It says "you think your car smells like this(shows dog sitting in car) but it really smells like THIS!" Whole car is a big shaggy dog)
They used MY car for the doggy car!! I am Mrs.USTABEE ( I used to be so particular.....) But I did get Febreeze..................................
Yes; it is impossible to keep the truck seats dog hair free with 2 bullies and a catahoula so we just keep our work clothes in plastic and change when we get there. It still doesn't keep hair off of us but that is why we buy lint rollers by the gross. hehe
