I can’t say I have experienced this…I usually catch Tucker in the act, and it takes at least two people to drop everything, corner Tucker, and get him to drop whatever it is in his mouth that he shouldn’t have, being a tissue, paper towel, anything small and plastic, or a pair of underwear. If I am alone, I usually have to use baby gates, chairs, whatever is in my way to catch him. He thinks it is a game. Sometimes I get very frustrated. (I must win, no matter what!) Tucker, as well as many, have brought out some pretty embarrassing items in the midst of company.
I can’t remember this with my other dogs, the sheer unwillingness to give up that prize. When I used “the voice” and said “drop it” they would drop it. From the other blogs I have followed, and articles I have read, golden retrievers like to hoard things, and bury them.
Is this the case with your Golden?
