I got a Kuranda bed (for) one year old German Shephard Koda. The vet said Koda limped due to a slight dysplasia in her hip, it was always worse when she got up from sleeping all night. They tried a foam doggy bed, but that didn't help her. I did some research and discovered Kuranda beds, and read the customer reviews about how the beds helped dogs with arthritis. I got them the Kuranda crate bed; Koda likes the Kuranda so much, she goes into her kennel (which is left open) anytime she wants to sleep. After only a couple of days use, Koda no longer wakes with a limp, and she doesn't constantly shift while she's sleeping to find a way to get comfortable.
