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.
