Large & Well Made
Pattern Name: Octopus
Although quite large for a small dog it does provide lots of entertainment. It's soft has crinkle in the legs which does entertain my little guy.

Great quality, great price, and pup approved!
Size: Pack of 100
This is such a good deal for the price!! Our order arrived faster than expected and was packaged securely. These ears are big too, much bigger and more natural looking than the ones I've been buying at the local store. Most importantly, the pups approve! Will definitely order again!
