Question

What is the tone and mood in the poem vern

Answer 1

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. 

Answer 2

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.
