Toto says "Greenies Rule"! It's her very favorite treat ... Patrick and I have to spell it in front of her ... she recognizes the word!!
She devours one of the little toothbrushes in just over an hour! She also poops green the next day!
Patrick picked up the wrong size one time and she had a difficult time with it and the next day she had loose stools ... no more of those! The problem I have with the rawhide ... it gets stringy and our grandpup, Missy the Border Collie almost choked to death on a rawhide bone! My daughter-in-law [a nurse] happened to be home and it took her a while to dislodge it from her throat ... she believes if she had not been there, she would have died. If they get rawhide I would supervise very closely while they are chewing it.
