We test the slow way. Weeks instead of afternoons, in real houses, with dogs that jump on things, dig at things and sleep somewhere else entirely if they don't like what you bought. Then we measure what's left.
Five best-selling beds, six dogs, six weeks and one ruler. Which covers pilled, which foam collapsed, and where the dogs actually chose to sleep once they had options.
Everything runs for a minimum of six weeks. Most gear survives the first week. The interesting failures start around week three, when the stuffing migrates and the seams give up.
Every product rotates through several households, from a nine-pound beagle to a ninety-pound shepherd. A bed that works for one sleeping style tells you almost nothing.
Foam height with a ruler on day one and day forty-two. Five machine washes per removable cover. And one question every morning: where did the dog actually sleep last night?
Writes the long-term tests. Lives with Moose, a seventy-five pound Labrador who has personally ended the lives of more dog beds than she cares to put in print, and who is the reason this site measures foam height with a ruler instead of trusting a product page.
