I consider my Sheltie to be an intelligent dog, but the noise of the toy makes him back away. And I can't tell you how many times I've "demonstrated" how to get the kibble out. He just waits until I do it. He could care less about the thing, and he's very food motivated.

Ex Output:
Negative

Ex Input:
If you follow their recipes precisely, with careful measurements, the freezer jams are excellent. Strawberry jam is particularly appealing. I've been warned that changing quantities of any ingredient will not have happy results.

Ex Output:
Positive

When we first bought these we tried to eat one and couldn't. Looked at the ingredients and found its mostly pig hearts. Taste is awful. Our dog however thinks they are great so we cut them up in small pieces and hide them around for him or forage out by smell. After about a week the contents of the bag start to mold. Since they are for the dog, we washed them off and then store in the fridge. Too bad we had hoped these would be good snacks for football parties etc. Not recommended for people food.

Ex Output:
Negative
