I find Vet Bed/Pro Fleece to be the best. My dogs destroy all bedding but because this has no stuffing it lasts a lot longer. The Pro Fleece is quite rip proof too - mine have a couple of holes but not bad after 3 years. They also wash and tumbledry well. They are design to soak up any accidents too.
Does anyone know where I can get these in the USA? I have been doing Google searches all day and can't seem to find any.
