I bought this because I was debating sending Toby, my 20.5 pound Pomeranian/Chow mix, to Iraq, thinking he might defeat the Arabs there, for us with his Crocadile-repellant breath. It would probably work, just as trhe good Dr. said it should, if I could get him to eat it! (Not the Vet, Toby!) So, my inventive, Dr. Jekyll side kicked in, and I not only mixed it into his food, but his food is already a micro-waved mixture, anyhow! Can you guess? He sorted out the C. E. T. HEXtra, and ate it first!! WOW! He thoroughly impressed me! Thanks, Dr. Ned!!!(In Eunice, La.)
