If not, and you're looking for information, a word of caution: Be very careful about using the aforementioned "a" word and the word "dirty" in the same Google search. You might think you're okay if you've got the word "dog" in there as well ... think again. Keep it very technical people, and you'll find the information you're looking for. When it comes to the practicalities though, a vet's instructions win hands-down over You Tube every time on this one!
