Great product and value for the money
Pattern Name: Half Ears, Size: 4 Pound (Pack of 1)
Dog loves these. I only feed her natural food and treats. These are very healthy. She's a strong healthy 2 year old puppy. Will be buying again soon. It is a great product for the money. They are chewed up in minutes because she loves them. They do have a bit of an odor but it's not overbearing.

A great natural treat option, my dog approves
Pattern Name: Full Ears, Size: 8 Count, Pattern Name: Full Ears, Size: 8 Count
Ingredients: Natural pig ears 👍, they smell smoky (my dog loves it, I don’t mind it), most of the time they are a decent size. My dog is half American bully and a heavy chewer so these are a great option for him. The quality is always good, and the bags I get are always fresh. These are a good treat for him when I have to sneak out for a bit or when I am leaving for work in the morning. I have purchased these several times. I also appreciate the eco friendly bag :)

Great Natural Chew Dogs Love, but Can Be a Bit Messy
Pattern Name: Half Ears, Size: 25 Count (Pack of 1)
These pig ears are a big hit with dogs and keep them busy for a good while. They’re made from a single ingredient, which is a nice plus if you’re looking for something more natural. They help with chewing and can support dental health by reducing plaque while your dog works on them. That said, they can be a little greasy and have a smell, which is pretty normal for pig ears. Also, they may not last as long for heavy chewers. Overall, a tasty and natural treat most dogs will love, just expect a little mess.
