Presenting the all-new MAD F90 M5 FATBOY Primary Downpipes – our most expansive offering to date!

Great value for money
Set name: Stuffed Animal Dog Toy Set (5 Pcs)
Toys are so cute and pretty durable for my puppy, much better and cheaper than toys from pets' stores.

Good stuffies for my Goldie.
Set name: Stuffed Animal Dog Toy Set (5 Pcs)
My dog is a heavy chewer so I don’t expect things to last long with him. But with that being said, he actually doesn’t go too hard on these stuffies and loves each and every one. Will they stand up to aggressive chewing? No they are stuffies. But for this price and for the quality, they are worth it for sure. Sometimes they don’t always squeak but I’m ok with that, because the constant squeaking can drive you crazy. I have a golden who can shove 3 of these in his big mouth but truly, one fits just fine. They are good sized for big dogs, it’s just that mine prefers to have his mouth stuffed like a chipmunk. He loves these stuffies and we will be ordering more for his endless toy box that I didn’t know I needed!

Good for puppies or dogs with little to no teeth!
Set name: Stuffed Animal Dog Toy Set (5 Pcs)
Good for the most part. Definitely not made for a heavy chewer! My dog shredded all 5 plushies within a couple days. Lol She got a hold of 2 them the first night and we woke up to a plushie crime scene. Fluff was everywhere and the squeakers were in pieces in the middle. The toys were unrecognizable, and no one could possibly have identified their intended animal shapes. Our silly girl was laying next to the massacred toys with what could only be described as a prideful grin.

Great assortment to keep the dog running
Set name: Stuffed Animal Dog Toy Set (5 Pcs)
My Jack Russell Terrier mix is madly in love with these squeaky toys. Every morning when he gets up he demands to have at least 4 throws of these as part of his morning ritual now. He loves them, and they seem well sewn and will last him quite a long time (but he has only a couple teeth), and they are washable which this dog mom likes. A good investment for my JRT mix.

Doggo Fun
Set name: Stuffed Animal Dog Toy Set (5 Pcs)
My dogs like these they were just smaller then I thought. They are made for medium dogs. Our big doggo can put the whole thing in her mouth. The squeek isn't too annoying and the overall make of the toy is nice. If you have a doggo that likes to attack and get the squeeker out this toy isn't a match for them. They will distroy it in minutes. If you have a dog that loves to just carry stuffies then these are good for them.
