I use the Merrick 6 inch bully stick and they last about a week. Dogs have a desire to chew on something, and this really satisfies that desire, and helps scrape teeth of tartar in the process. Joey pretty much has access to his stick at all times, and when it gets too short he makes us hold it for him. I wouldn't worry about them chewing so much that the gums are bleeding, if this has happened to a dog, the dog may have had gingivitis, and the sticks actually help prevent that. |
