I looking to purchase either a Orthopaedic Dog Bed or a Dog Cot. Which would be the better choice? If you have tried both, which did you prefer? Which did your dog prefer? I saw some cheap priced cots at walmart, but I'm wondering how the quality of those compares to some of the "name brand" cots? And if anyone knows any good deals going around, please let me know! Otherwise I shall continue shopping around .
