Mom

a melodrama
where the voice is cut
from its body:

           first my dog, now my grandma? ...clever....but is it necessary?

red drunk she cursed
her wounds and the houses
that held them and the houses
that held them and ....this hints at the subject of the poem having something to do with domestic abuse, but the wounds could also be mental, psychological damage. The problem is that everybody is a victim these days, and so I instantly smirk at this sort of melodrama....but hang on! you said it was a melodrama. Smart.
But from a purely aesthetic standpoint, I don't find the above lines do anything

today it's spring
we survived
good years
and new griefs
and know new dogs that are old
and growing older and ... dogs age in the blink of an eye, and anything that you love can also grow old quickly. I love this line. 

how does one write about your brother? ...this bit remains an enigma, but allows for each reader to interpret differently

the pictures in the hallway are quieted
by fleeting hours
and the valley out the window
grows so dark it's
as though it were never there
as though it weren't 
someone's eternity and  .....these are some wonderful, moody lines

what i really mean is
how do i write about your brother
without writing about mine?

i imagine myself stepping out 
that valley-window
not believing in anything
but moonlight. ...a beautiful end to the poem. I didn't understand the poem, but I enjoyed reading it.

It's an amazing mood poem. Not to my taste. I am fine with understanding something at a literal level, and then not getting the second or third layer of meaning, but this one is hard to understand literally. 
I don't think there's a lot that you can fix without ruining the poem though, so there's that.
