Best Friends by Sheri built its reputation on the calming donut bed, and the lineup now spans several sizes and styles. In our evaluation we compared how each model fits different dog sizes, how the raised rim supports dogs that like to curl and lean, and how easily the cover washes. We recommend choosing by your dog’s sleeping style first. Curlers and nesters tend to love the high-walled donut, while dogs that sprawl may prefer a flatter lounge. Match the size to your dog’s weight so the bed feels secure without being cramped, and plan to wash the cover regularly to keep it fresh.
