I just read through this thread and it brought back (painful!) memories. Fortunately I do not currently have any dogs or cats to pill. They all seem to figure out the food disguise thing sooner or later, and then it's back to opening the mouth and shoving it down…...and hoping it doesn't come right back after the swallow. I had one girl that I swear could fake it every time, then back would come the pill. Cats are worse! That shallow mouth makes it harder to avoid getting nailed with the canines. My biggest laugh was my Border Collie. He spit out the pill one time, and I expressed my disapproval, at which he said "sorry Mom" and picked it up off the floor and swallowed it! Would never happen with a Basenji!
BTW, be it dog, cat or horse, I have always found it easier to work alone. Too many people ganging up makes the animal suspicious and much more likely to fight. If you have the right relationship with your pet you should be able to finesse it alone just fine. Lots of love and treats (if appropriate) afterwards takes the sting out of it. I am convinced animals read your intention and allow even painful treatments if they trust you.
