I've always used vetbed for my dogs and believe me, it can take a lot of abuse in the washing machine and in the tumble dryer. I always wash it on at least 60 degrees and, depending on how I'm feeling, I either tumble it or just leave it to air dry. It does 'clump' a bit after you've washed it and the cheaper immitation vetbed is worse than genuine vetbed. Still works just as well though for a fraction of the cost.
