children's chapter book told from the pet dog's point of view

The back of the book had a glossary of terms the dog used to describe "human items" that he didn't know the actual word for. He was a yellow lab, I think.

The only plot point I remember is that he got shot in the tail despite living in the suburbs, because that was such a shock to me as a kid.

I remember the cover being blue, and I had it in paperback.
