First we had to explain the idea to him. The photo above shows Bingo with his back to the camera watching as Jan demonstrates how to put on the Reindeer antlers. Bingo is wearing his holiday necklace of snowmen.
In this next photo Jan is holding Bingo's snout down while he looks up in dismay at the Reindeer antlers being held up over his head. Bingo is getting the idea that Reindeer antlers need to be worn actually on the head, preferably, his, and that must involve getting the elastic band around neck, hence, the dismay.
Our first attempt at a quick shove and hope for the best results in a mangled Bingo with the band NOT going around his head, but instead going ON TOP of his head where it isn't supposed to go. Bingo looks slightly crazed. We're chalking that up to the elastic band and not to us making him wear the Reindeer antlers.
