It was a toy so he hid it. When Eddie was trained he got a toy as a reward to play with. So he hid the toy in the cupboard so he wasn't confused it was there to play with....
I have no reason to wish to change your opinion, however I am hoping that maybe handler may think back and possibly recall, oh yes actually, the clothes in that box were actually in the living area when Eddie was searching
every inch of it, lets see, do I remember where exactly in the living area those clothes were.
I might be wrong (BTW feel free to C+P those 4 words and use to enhance your posts, free of charge).
And just to clarify, in my very amateur opinion, Eddie was always correct and always consistent.
BTW somewhere I read an opinion that the 2 dogs in PDL now are better than Eddie. You say Eddie prioritised a play response and suppressed a bark response. So if I wish to conceal a body I will simply place a kermit the frog and a tennis ball on top and that will fool Eddie and Muzzy and Tito IYO?
