Hondo will not take a treat from someone he doesn't know. He won't approach them for a treat. He'll ignore them totally. If they walked over and put the treat in front of his face he'll provide them a healthy dose of the Hondo Stink Eye, but still will not take it. You could toss it to him and he'll ignore it.
Lonestar, my Lacy will not only accept the treat with a huge amount of unhealthy (for the treat-er) enthusiasm, but will make every attempt to find the treat source. Including but not limited to climbing the treat-er to find said treat source.
Tug, my Golden will not take a treat but will take a toy. If the treat is thrown in his direction he'll eat it. He will not take it from a stranger's hand.
Maggie, my Mini Doxie, will take the treat and then pledge her undying love to the stranger for as long as she lives.
