Can I put my little dogs treat in the mouse trap?
That's strange. Why would you hide your dog's treats in a trap?
I love to hear him squeal when his little nose gets pinched in it.
Sticking your dog's treats in a mouse trap is not funny and it is dangerous for your dog. Find another way to have fun that doesn't involve harming your pet.
He is never going to die. It's just a bit of fun.
But that bit of fun is painful for your pet to experience. You shouldn't do things to your pets for a laugh. You are supposed to care for them since they need your protection.
