This would make more sense with a parallelism. Since the dog is doing something ("skimping"), the telephone should also be doing something (i.e. floating).
Speaking of what the dog's doing: "Skimp by" is the wrong way to use 'skimp.' To skimp is to get by with the least effort possible. Perhaps you mean something like "treads water," but changed with 'white' to remove the overt reference to water:
I watch a dog with no face skimp by tread white. A telephone able to contact other worlds floats by.
This sentence uses past tense when the sentences before and after use present. Change it accordingly:
I tried try to run, hide, but there was is no hope.
"Crouching down on knees" lacks a cohesive mental image. In fact, "crouching down on knees" sounds like 'kneeling.' Switch that, and then find another verb for what you meant next. You can use something else, but I use 'bow' here:
I crouch down on my knees kneel, and kneel bow to my fate
'It's' the contraction, not 'its' the possessive:
But maybe it's for the better.
Same here:
After I think it's all over, I see it.
Quotation marks after punctuation:
Clearance Level 4."
Comma after 'scream.' Also, the word choice and phrasing is weird – "fade off" by itself is an unused expression ("fade away" is much better), and "suffer my very fate" is a weird twist on the idiom "suffer the same fate." Here's how I'd change it:
As I scream, I watch Calzaroli fade off away as he suffers my very the same fate.
'Frail' is not a verb (at least, not with the right denotation). You want to use 'wither' instead:
I begin to chip and frail wither.
