These pig ears are big
Pattern Name: Full Ears (25-pack)
These pig ears are pretty big, great for large dogs. My dogs love them! I keep them refrigerated, for freshness and my dogs love them cold.

Good but a bit overpriced
Pattern Name: Half Ears (15-pack)
I like these as they are a good size and not as greasy as others. I have 4 dogs that get one each evening. It would be nice if they were a bit cheaper.

Apparently delicious to dogs!
Pattern Name: Half Ears (15-pack)
Bought these hoping they wouldn't be too large for my 10 lb. dog, and found that she loves them so much it doesn't matter that she can't finish one all at once. I think they are her favorite treat, and can last her days, so it is a great deal both for her, and for my wallet! (she also doesn't get them more than once every week or two!)

Chew that pig ear doggie
Pattern Name: Half Ears (15-pack)
These are halves of pig ears. My little dachshund doesn't need the entire ear. Half is much better size. And still we break the halves in half. She loves them. Helps clean her teeth while she is chewing and destressing. I would recommend to other dog owners.

So nice I ordered a second bag!
Pattern Name: Full Ears (25-pack)
I can’t say that ordering this brand has always been a success. I was ordering half ears. Then one bag came without an expiration date and they didn’t look so good. The next time I bought two of the smaller bags instead. Those ears seemed too small. Mostly OK though. Expiration date on the bag. But this last purchase of full ears looks really good. Expiration date on the package is 12/26. We are nearing the middle of May. So I ordered another bag. My piano teacher (weekly lesson) has two big, tough, but sweet dogs. They watch for me to come up the walk and wait at the door for their pig’s ears 🙂. Thanks! Update: second bag has September 2027 expiration date. Beautiful ears. Delivered next day and I don’t even have Prime. 🙂. Thanks!
