K&N Oil Filter (HF139)In the early 1960s, two motorcycle racers, Ken Johnson and Norm McDonald (K&N) developed a ground breaking new idea for an air filter. After experimenting with numerous types of filter media, they discovered that an oiled cotton design allowed the filter to not only capture contaminants very efficiently, but also allowed it to be washed and reused, and the original K&N High Flow Air Filter was born. Five decades later, K&N is still innovating industry

Adorable but not holding up well
Color: Green, Pattern Name: Puppy
They’re super cute, have a great variety, but my puppy whose 2 months old and only 9/10 lbs has chewed through the plastic parts already and it’s only been a week or so, they arnt holding up very well for larger breed puppies.

Fun for Pups and You Can Hide a Treat Inside!
These chew toys are fun for my pup! He especially loves that I can hide a treat inside, which keeps him interested and entertained. They’re a nice size for small dogs and puppies, and I also like the light colors because they’re easy to spot when they end up under the sofa because somehow they always do!

Cute toys but not for tough chewers. Might be too thick for my 6 lb girl
These are fun for the right dog, but not a good choice for all. They're a good size for medium dogs and some small dogs, but "small" is relative I guess and the size of this toy won't work for all small dogs. I definitely expected these to be smaller, though I measured and they are the size shown in the listing (for those in the US it's about 2 1/4" by 4 3/4"). I think one thing that surprised me is how tall (?) they are, or maybe thick? They show two measurements in the listing but not the other. That's the one that makes a big difference with small dogs, especially really small dogs like mine. I have a 6 lb Maltese with a teeny tiny mouth so I have to find toys that she can fit her teeny mouth around. She loves toys with nubbies and has other "spiky" toys like this, but so far hasn't been too interested and I wonder if it's because it's too thick. If she doesn't give them a try we have doggy friends who are big enough for them, more the 12-16 lb size.
There was a bit of smell on them when I first opened the package, but after giving them a quick wash (which I do with all chew toys like this) the smell was completely gone. Whatever it was must have just been on the outside because it hasn't come back.
I can't really say how durable these are, but I doubt they'd be good for tough chewers. They're not super soft but in the world of dog chewing they're medium at best. They're very cute and if you have a medium to soft chewer they could be a great addition to the toy basket. They also have a hole down the middle which could be filled with something to lick out, another way to keep them busy. Can't say any of this makes them worth the rather high price asked though.
