THE DOG TREATS SO GOOD EVEN PHOEBE KNOWS THEY ARE FROM A WINNER
Size: 1 Count (Pack of 6)
These Wonder Bound pig ears are absolutely INCREDIBLE. Truly one of the greatest dog treats ever created. People come up to me and they say, Sir, my dog has NEVER reacted to anything like this. And I tell them, of course not. These are REAL pig ears. Not the fake tiny pieces you get from weak companies. These are STRONG ears. Beautiful ears. Now I do not personally eat pig ears. Everybody knows this. I have a tremendous diet. Very refined. But DOGS, they understand things on a deeper level. Dogs know QUALITY. Dogs know WINNERS. Some people don’t, but dogs do. And Phoebe. Very smart dog. People tell me she is one of the smartest. Incredible instincts. She saw this bag and immediately knew it was the BEST. Not good. Not great. The BEST. She did the excited thing dogs do. Very respectful. Very appreciative. Some say she even endorsed it. I’m not saying that. But many are. She took the ear and ran like she had just made the greatest deal of her life. Tremendous speed. Very athletic dog. Very loyal. And she chewed it with POWER. You could see it in her eyes. She was thinking, This is from a winner. Dogs sense that. They really do. The size is perfect. Not small. Not flimsy. A whole ear. The kind of treat a DOG OF DISTINCTION deserves. It keeps them busy, focused, and happy. Very important qualities. And let me tell you, Phoebe looked extremely satisfied. People saw it. They said, Sir, that is a dog who knows success. Five stars. Would buy again. If I were a dog, which I am not, I would ONLY eat these. They are THAT good. Just ask Phoebe. She knows.

Jake the Chocolate Lab Can't Tell You- But He Liked Them.
Size: 1 Count (Pack of 6)
I suppose that I should give you the details of my experience with the product. They came in a quality, resealing bag. I actually ordered this item from the Amazon page. I got them for my parents' dog Jake- a three year old chocolate lab. I hid one in my hoodie pocket and he began zeroing in on that area after a few seconds, wondering what was in my pocket. It may just be me, but if you aren't familiar with pig ears- they don't stink or anything like that. Yes, they are actual pig ears. But they contain pork and are a decent snack for dogs every now and then. In retail we would always sell out of pig ears. I took the pig ear out of my pocket. Jake took it in his mouth and proceeded over to his bed area where he licked the pig ear for about a minute, probably because it is salty. I don't wish to find out. He then carefully munched down on it and took a short drink of water. He then proceeded to run over and tackle me (as he is wont to do). Oddly, his breath did not stink. I bought these as an alternative to rawhide. Two decades ago I got my parents to stop buying rawhide (about as gross as beef 'pizzle' and instead buy pig ears and deer antler chews. He seems to like them, and if they aren't causing an issue I don't see why Jake can't have one every now and then, especially when he behaves.
