The piggy bank trick is going very well, Mazzel can now put a coin in a hole that is just a little bit bigger than the coin.
I only have trouble getting him to put the coin in the hole, the way you have to do with a piggy bank (so vertical).
Anyone ideas?
Maybe try with something bigger than the normal piggy bank vertical slot. You may have to 'make' something which resembles a piggy bank slot only larger.
Maybe put the piggy bank on it's side so the slot is horizontal at first, then gradually raise it up to the vertical. I would imagine it's hard for a dog to get the vertical slot.
