So my dog was whining for attention, so I decide to buy some peace by giving him a rawhide. So I get a handful out, so I can bring some upstairs for future buyout opportunities. I hand him one, which he excitedly takes. Then he sees that there are, in fact, other rawhides that he does not have. Now he refuses to chew the brand new one that I moments ago gave to him and he demands to have one of the other rawhides. I tried a trick of taking his, hiding them all, and then giving him back the same one he had. Of course he can somehow tell. So I just take his, put it back in the pile, and give him one from the larger set, and he happily goes off to chew. I suppose the rule is "that which I do not have, I want, until I have it, in which case I want the other thing now". I just found this to be a Funny Moment in Dog Psychology History.
