Hi there, so my dog loves these things but when they get to 4 inches he swallows them, the result is him waking up in the middle of the night gagging and he evenutally throws this 4 " piece up, YUCK! now I know the answer, take it away when it gets small. Curious if anyone else has this problem? How can the dog physically throw this long thing up. He he doesn't get it up, it could rip him inside right? anyway to teach them not to swallow that much!
