I have a theory: each of my dogs has a certain number of hours during any given 24 hour period when they are perfect angels. It’s a different number for each. But if you trust them beyond those hours, bad things happen.
For example, we decided to let Murphy have the run of the house last night. No problem at all – as far as I can tell, he slept outside our bedroom door all night. This morning, however, having used up his angel-puppy hours overnight, he decided that the welcome mat would make a tasty snack while I was in the shower.
Good thing both our dogs are cute!
