For most 25 lb dogs, a medium dog bed is the sweet spot. In everyday sizing, that usually means a bed with an outside length around 30–36 inches and an inside sleeping area around 24–30 inches, depending on how thick the bolsters or borders are.
The best fit depends on how your dog sleeps:
Measure your dog from nose to base of tail while they’re lying down in their favorite sleeping position. Then add 6–12 inches. The lower end works well for curlers, and the higher end is better for dogs that sprawl or like extra room.
A 25 lb dog benefits from cushioning that keeps elbows and hips comfortable, especially on hard floors. Look for a bed with durable fill and a non-slip bottom so it stays put when your dog steps in, spins, and settles. Washable covers are also a lifesaver for muddy paws, shedding, and everyday freshness.

A 25 lb dog is typically considered small-to-medium, and many brands place them squarely in the medium range for beds, harnesses, and apparel.
A good rule is 6–12 inches longer than your dog’s nose-to-tail measurement. Choose closer to 6″ for curled sleepers and closer to 12″ for sprawlers.
At 25 lb, many dogs are compact but sturdy—often similar in size to breeds like a small Border Collie mix, a Beagle-sized pup, or a slim Frenchie mix (sizes vary by breed and build).
