At first, I was hesitant to buy another antler chew because my dogs in the past have not been very fond of them. Granted, I had never tried a split antler or this brand so I decided to give it a shot with my new dog. He is not a problem chewer but he likes to have something to gnaw on and he is in the office with me all day so I wanted something that he would enjoy, that would keep him busy, and that wouldn't be eaten up in a day.The first time I gave him the antler, it was clear he had never been given one before. He was very curious and just sniffed it a lot at first, but after a few minutes he was in love! He really likes the exposed marrow and definitely targets it when he chews. As a result, the marrow has broken up a bit and will not last as long as the antler itself but he also enjoys just chewing on the antler so I'm not that worried about him eating all the marrow out of it. He chews on it in short bursts throughout the day and he's had the antler for a few days, and there's still plenty of marrow. The outer antler looks untouched. I anticipate this antler lasting him at least two weeks if not longer. It's possible, if your dog is a powermouth, that they will clean out the marrow very quickly but the bone of the antler will last them.I highly recommend trying the split antler before the whole antler if you're unsure how your dog will like chewing on an antler or if you've tried whole antlers in the past with no luck. I plan on ordering either the Large whole or the XL split when my dog is done with this Large Split but I'm happy that I tried the split antler first. The marrow entices them to chew more than just the flavor of the outer antler.No odor, no slime, no splintering. It's a great length for my dog (Lab/GSP). If your dog is a heavy chewer, you should get at least a week out of this chew.The length is a little deceiving. When I unboxed the antler, I was sure it wasn't the described length (6-7"). It definitely looks about 4-5" but I measured it out of curiosity and it is indeed 6.5".Very pleased! Do plan to purchase from this seller again.
