Perfect Calming Bed for Puppies
Color: Dark Gray, Size: Small - 23”L x 23”W x 8”Th, Color: Dark Gray, Size: Small - 23”L x 23”W x 8”Th
I bought this calming dog bed for my 10-week-old puppy and he absolutely LOVES it. The moment I put it in his pen he curled right up and fell asleep. The soft, fluffy material is incredibly cozy and supportive, and the raised edges make him feel safe and secure.
As a new puppy owner, I wanted something that would help him relax and settle down, and this bed works amazingly well. He sleeps so peacefully in it and clearly feels comfortable.
The quality is great, the cushion is thick, and it holds its shape nicely. If you have a puppy or a dog that likes to curl up, I highly recommend this bed. It truly is a calming bed!
Bonus: it also looks really nice in the crate.

Amazingly soft! My dog loves it!
Color: Dark Gray, Size: Medium - 30”L x 30”W x 8”Th
If you follow the instructions inside for fluffing the bed, it's AMAZING! I myself sat in it and it was so soft and very comfortable. (I need one for my bed!😆) If you also follow the sizing chart, it's pretty accurate. My dog loves it!

Great quality bed that my babies love
Color: Dark Gray, Size: Large - 36”L x 36”W x 8”Th, Color: Dark Gray, Size: Large - 36”L x 36”W x 8”Th
This dog bed is exactly what I was looking for! It's like a big pillow that my dogs love. My cat even loves the bed, he tries to steal it every chance he can lol. I was a little skeptical when the box arrived, but after opening and bluffing, it's good quality and super soft! I love that it can be thrown in the wash.

nice quality but small is too small for a 22 lb pup
Color: Beige, Size: Small - 23”L x 23”W x 8”Th
gave 4 stars due to size, quality seems good, its very soft and thick as well as decent looking for the money, however the small says it fits up to 25 lbs and my 22 lb Frenchton (boston/frenchie mix) barely fits in it. In their defense if I didnt just pay attention to the weight and looked at the measurements then I would have bought a medium so its my fault too, but my advice if you have a dog over 20 lbs I would definitely get a medium

Loved by both dogs!
Color: Dark Gray, Size: Large - 36”L x 36”W x 8”Th, Color: Dark Gray, Size: Large - 36”L x 36”W x 8”Th
My dogs love them! I wanted something light but comfortable for my dogs (who are extremely picky and don’t like to sit unless there is a cushion to sit on) as secondary beds to easily move around the house as needed. These are perfect and also super cute. I ordered one to test it and immediately ordered the second after the first one arrived. I have a 56 lb. And a 100 lb dog and they love to curl up inside and use the ‘pillow’ to support their head. I ordered the 36” but if your dog likes to sprawl out, I suggest getting the larger one for comparable sized dogs. The pictures are of my 56 lb. dog for reference.
