FUR BABY APPROVED!!
Pattern Name: 8PCS No Stuffing Dog Toys, Pattern Name: 8PCS No Stuffing Dog Toys
I have 2 spoiled little diva fur babies that are very picky when it comes to their toys. I have an 8lb, 10 year old Schweenie (Shih
Izu/Dachshund mix) and a 1.5 lb, 11 week old Yorkie and they both LOVE LOVE LOVE no stuffing/crinkle toys. Unfortunately, we don't have many because they're hard to find and usually overpriced. This set here is worth EVERY PENNY!!! I was genuinely so shocked when these arrived. This whole set is by far the best I’ve seen or bought. Each of the toys in this set have been created with a very high quality textured fabric. Each is a different design, color and texture. As an experienced seamstress, I can confirm that each of these toys have been carefully stitched to withstand lots of play time, chewing and games of tug of war that involves sharp little teeth. This set of toys range in size from about 5” to 10”. I highly recommend this set.

Perfect for my 2 pups!!
Pattern Name: No Stuffing Dog Toys
I have 2 black Labs, one is 2 years old and the other 4 months. They LOVE to play tug o war and wrestle with toys, but my puppy with her smaller mouth and baby teeth has a hard time holding the stronger silicone chew toys (we love the brand west paw) my older dog likes. Ropes shred and are annoying. They love plush/soft toys, but once the stuffing comes out they start eating it so it’s game over. I still would get them cheap dollar store stuffies just for 10 mins of supervised fun, then they’d go in the trash. THESE however bc they have no stuffing or filling whatsoever, my dogs can just tug and tug until the fabric literally falls apart which is perfect!! With each toy we’ve gotten well over an hour of playtime, which is amazing. And they tug HARD... so while they may rip an arm off the octopus or a claw off the crab, the body stayed intact so they could keep playing. I was very impressed with the durability of the fabric. These satisfied our need for a fun, cheap toy that we were okay with getting destroyed eventually.
Will these last forever? For a big dog/tough chewer no, but they’re cheap and provide some serious fun. Yes they’re flat - they have no filling. But they are soft and adorable!! And approved by my two girls! I highly recommend and will buy again!!

Not for large dogs or chewers
Pattern Name: 8PCS No Stuffing Dog Toys
These are not for large dogs. They are cheaply made. They get dogs attention because of squeaker and crinkle but are easily torn apart (cheap fabric and felt). They might last with small dogs or puppies. Definitely not for actual chewers. Didn’t even last 15 minutes.

Sleep like a baby
Bringing a new puppy home can be rough on both of you, but this little heartbeat soother made such a difference. The first few nights my pup was whining constantly, but once I tucked this into his bed he settled down so much faster. The heartbeat sound is realistic and soothing — not annoying or too loud. It’s compact, easy to turn on, and the design is simple and clean. Great for separation anxiety too, not just new puppies. Totally worth it for the peace of mind alone!
