One of my dogs likes to “dig” into the pillows before he lays down and it always rips the lining underneath the cover. This mesh bag saved me from having to throw out another pillow and cleaning up memory foam pieces every time I have to wash the pillow. Love it!Using this bag was a great idea to make sure my pillow stuffing was in one place. I was able to empty 5 pounds of fiber into the sack and then stuff the sack into the dog bed. The sack created the perfect holding place for the willy fibers who otherwise would be flying all over the room. This sack offers a zipper closure and small air holes to let the scent out if needed. If you wanted to stuff your dog bed with familiar scents like an old shirt or socks the zipper closure keeps the items secure. You can even place your scented items on the top of the bed so Fido can lay directly on top of the known scent. My dog is very happy with the shape of her bed and the feeling that it is now more secure and less floppy.I purchase this bag along with the water resistance cover and the Molly Mutt canvas cover and filled it with old clothes. It was way too heavy to move around and the dogs wouldn't lay on it. I removed the clothes and filled it with pillows, the dogs love it.GreatI have little dogs that each like to sack out in the middle of a large bed.Regular dog bed covers, in general, do not come off easily or at all for washing, and washing a large bed filled with stuffing material is a hassle. If I don't wash the dog beds regularly, they get stinky. As an alternative, I got these stuffing sacks and fill them with soft dog blankets.I do like these stuff sacks, but they are huge and take a lot of stuffing. Be warned! Also, make sure you cover the netting with a sheet or blanket so your dog's nails don't get caught in the netting.Works well and is cheaper than buying a whole bed, even when you buy the duvet. I tried stuffing it with old t-shirts but it wasn't fluffy enough and heavy to pick up! I used the stuffing from my old bed pillows and it works great!My furbaby loves it! I stuffed it with our old pillows and she absolutely loves it.I purchased this to try and find a cost efficient way to provide a bed for my dogs while still being able to clean the dog bed via washing machine. The idea was great but unfortunately after actually trying it out I realized that just simply stuffing old clothes in here is not as comfy as you’d think and all it does is create a lumpy and stuff bed for your dogs. Unfortunately, I passed the return window so now it’s just sitting here with money down the drain. Don’t make my mistake. Just buy a proper flat bed insteadExcellent product and serviceI have older dogs and one with incontinence that is treatable but doesn’t get rid of all the accidents. This allows me to wash and disinfect easily by removing the cover, lysolling the waterproof interior and slipping a new cover on. Even my son has noticed that house smells so much better and it’s so much easier to maintain the level of clean I prefer. My allergies also love the covers and waterproof liners that cut down on dander going into the stuffing and the covers that are easily washed. Sanitary, durable, easy to clean...brilliant. Well worth the investment.A penas lo empezamos a usar, y hasta ahora todo bien. En la descripción no vienen las medidas entonces hay que buscarlas por otro lado para no errar en el tamaño, y así elegí el indicado. En unos meses más pondré otra opinión actualizando el estado del saco.Las camas que he comprado para mi perruna, todas han sido lavables, el problema es que el saco donde viene el relleno es muy delgado, y a la primera que sacas el saco de la funda se empiezan a romper y en un par de meses ya son pedazos de tela que es muy dificil sacar para lavar y luego meterlo en la funda es un desastre! Compré este con la intensión de poner ese relleno en este saco Molly y ver si así restiste más y me es más facil lavar la cama. Por ahora muy bien, fácil de usar, se ve que esta hecho con material resistente, pero aún quiero ver en unos meses si sigue en buenas condiciones. Recomiendo checar bien las medidas en la pág. de la marca. Como actualización, ya pasaron 4 meses y sigue perfecto!I love this so much! I had one dog bed in my dog's Molly Mutt duvet cover, but it was thin and I was worried it wasn't comfortable enough for her. I have an old crate pad of hers that I also wanted to use in it, but I didn't want the duvet to lose its shape. Now I have the thin dog bed, an old crate pad, 2 old sheets and 2 pairs of pants that I otherwise would've thrown away in it. It's much more comfortable for her now and I've noticed she's been going in it a lot more.Love the concept is stuffing old t-shirts/clothes into sack. I put inside the medium-size sack two old King-sized pillows. They fit perfectly. Our dog goes crazy for dirty socks, underwear and pj's, but I found our old king pillows work best. You can literally stuff anything into it. I suppose I could still ad some dirty socks to it for some familiar scent...lol. Definitely recommend their products. Very well made. Good price for the quality.
