Oh this is a truly sad one, such beauty in your title and in every line, your last two lines have brought a tear to my eyes. I love your reference to canis major, you always bring something special and you always bring such style. Your imagery goes into infinity.

Dear Michael, what a lot of feeling there is in your poem. So sorry about your mother dying so recently. Writing poetry does keep grief at bay, somewhat. I used to write about my lost loved ones to keep going on in life.
I see that some corrections have already been pointed out. I also like your Canis Major reference. Brings something special to your piece.
I find your poem is a consolation to me as well. Thanks for that, Gracy

that your mother was not just an animal lover, but in particular a dog-lover? I love the reference to the Dog-Star too! A piece that gives voice to the anguish that losing a loved one brings. A tight, well-written poem of pain. ~ Geezer.

I love this poem so much, it is quite painful but in the best way. I am obsessed with the title aswell, this poem is really something!

My heart and sympathies go out to you, and I am sorry to hear about your mother's passing. This is such a beautiful, heartfelt poem that left me reeling from memories of my own grief dredged up once more. Beautiful poem, as always. <3
