Mine get an occasional pear off the tree when they are ripe, tossed to them in the pasture. Aside from that I only have one that gets treats, she's 20 and came to me having been given treats her whole life so I let lesson kids give her a sugar free peppermint after lessons are over. The rest have never been given treats so they won't take anything even if offered.
Life is like a camera. Focus on what's important, Capture the good times, Develop from the negatives and if things don't work out, Take another shot.
