…What puzzles me is dogs need 10 essential amino acids...
Wikipedia contends that taurine, although often called an amino acid, is not, see:

…And again-don't discount the need dogs have for fruits and veggies. See if you're dog will eat veggies. Not only does this provide nutrition they need, it fills them up without added calories, and I've found giving them pieces of fruit and veggies during the day helps relieve the B's throwups sessions! (something in the tummy gives the bile something other than the lining to work on)...
I personally don't believe dogs need fruits, veggies or grains. I believe they may eat them opportunistically but wouldn't eat them on a regular basis if meat was available. No disrespect intended, JMHO. I occasionally offer my dog veggies (I haven't found one yet that he'll eat) and fruit (he'll offer a perfunctory lick at a piece of apple or orange, but won't eat it) as rewards or treats, but do not use them as a staple of his diet.
