Milo sniffed the pig ear, paused, and then took it to his spot to eat it. A few minutes later he started rubbing his head on the floor. I also bought the cow ears and he ate them with no problem. I’ve snuck him the occasional piece of bacon so I don’t think he’s allergic to pork. I love and trust Nature Gnaws.

Great quality!

Flavor Name: Pig Ear, Size: 8 Count (Pack of 1)

I do not review items very often, but after considering that I have ordered these no less than 30 times, I decided it was time. I have four dogs who absolutely love them, so I go through them pretty quickly. They are generally very large, with occasionally one smaller one in the bag. These are the best price/quantity pigs ears I have been able to find. Each bag has eight ears. My dogs range in size from a (very food-motivated) mini dachshund to a pit bull, so the treats are good for any size. I order them for my sister’s and my boyfriend’s dogs, and my boyfriend breaks them in half to give to his dog if you don’t want them to have the whole one all at once. Would highly recommend!

Perfect toy for an active dog!

Color: Large size (7.9")

My dog absolutely loves this ball with handles! It’s quickly become one of his favorite toys, and he gets excited every time we bring it out to play. The vibrant colors are a huge plus—they make it super easy to spot in the grass, which saves a lot of time during outdoor play sessions. The handles are great for interactive play too, especially for tugging and tossing. I’m really impressed with how well it’s holding up. Even with constant pulling, tugging, and rough use, it’s remained durable and hasn’t shown any signs of wearing out. Overall, I’m very happy with this purchase—and if my dog could write reviews, it would definitely get his paw stamp of approval! 🐾

Not for strong chewers!

Color: Large size (7.9")

I have an English Springer Spaniel who is 1.5 yrs. She had this torn apart within the first 5 minutes. This is not for strong chewers!
