I love these Elk Antlers. My Bailey is a 7 year old lab/pitbull mix who has destroyed every other chew I have given her within a matter of minutes. These Elk Antlers are strong and durable, they last months and she LOVES them. They have saved me a great deal of money as I am not going through chews so fast anymore. The service is excellent and I always get a sweet thank you note on the invoice from the company. I will continue to buy these chews for my dog and have recommended them to several friends.
