Well from what I remember from the poem Vern by Gwendolyn Brooks, it was about having a puppy as such a good companion, so in my opinion the tone seems to be warm and happy and I'm assuming the mood would be the same as well. 

Tone is the feeling displayed by the author toward the subject of the poem.

Mood is the feeling created by the poet for the reader.

It is a warm poem that talks about love and warm that you can obtain from having a puppy. It seems the author had a great love for his dog and wants to communicate and share that feeling to readers by inviting them to have a dog.
