Good replacement insert

Ordered the Shredded Memory Foam (M) to replace existing insert. Fit perfectly, and my dog went right to sleep on it!

Better than the rest

Over the years I've accumulated a collection of dog bed inserts. They all lost their cushioning over time and I would end up stacking 2 or 3 inserts together to make one dog bed. I have a new rescue (formerly feral) dog and decided he deserved a new mattress. I am a first time customer and was impressed with the quality of this bed. They are very generous with the foam and it's very got a cushioned feel, not hard. Best of all my dog loves it.


Insert with striped cover is perfect! Pax LOVES it :)


I previously commented how stiff this bed was but the Foggy Dog team reached out to me and suggested I remove some of the full from inside of the pillow. I did so and the pillow is much less stiff and seems a lot more comfortable. My puppy seems to really love this bed as I bought him another one and he still chooses this bed.


I got the memory foam bed insert and the striped dog cover and the memory foam bed insert is extremely stiff and seems uncomfortable for my dog to lay on ( I would not even want to rest my head on this). Idk if my dog needs to break it in? But if so it seems uncomfortable for him to do so in the meantime idk if it is supposed to be so stiff?? I got the large and for everything together it is overpriced imo.

Hi Heidi, thank you for sharing your feedback and I'm sorry to hear that you found the shredded memory foam to be stiff. Shredded foam does have a different feel than a traditional polyfil bed, but many of our customers prefer it because of the additional support it gives. If you want to adjust the amount of fill, you can unzip the memory foam shell and remove filling as you see fit. I hope that helps! - The Foggy Dog team

Dog Bed Fill Options

    Buy just the cover and fill it with old pillows, towels, sheets or clothes. An easy and eco-friendly way to upcycle old linens that's especially popular for pets with anxiety issues because they find your scent calming.

  • Eco-friendly Recycled Fill

    Eco-friendly fiberfill is spun from plastic bottles destined for landfill. Made with extra loft to stay comfy for years, and channeled to prevent fill from clumping. Water resistant liner helps guard against accidents.

  • Shredded Memory Foam

    Our most luxe fill for the pup who likes to relax in ultimate comfort. Shredded memory foam fill eliminates pressure points for cloud-like support. Water resistant liner helps guard against accidents.
