Assault dobermans have even less use for people without doggie biscuits.
Not that I’d know from experience or anything....
Mine won’t take treats from strangers.
Even if I “okay” the treats, they just stand there and stare at them.
At PetCo last Sunday, I had to give Odin the treat the cashier gave him as a birthday gift and even then, I had to break it up into tiny pieces and “nibble it” before he’d eat it.
