Poem writer

I am writing a book on pet bereavement for the general public. I am looking for a writer who understands the loss of a pet and can portray this in poetry. The book I am writing will be dominated by poetry that will help bereaved pet owners. I would like one or more of the poems to include feelings of guilt, loss, anger and hope. I would also like some poems to be about happy memories of their pet. I would like 10 poems.
