Q. My pitbull has been having trouble breathing through her nose. It's been getting wrose. No discharge but it's seems like she is totally blocked up.
A. I would take her in for a check up with a vet. It could be a number of things, likely with her respiratory system or lungs, more worrying if it is a sudden onset. It is possible she has something stuck in her nose, something irritating her nasal passage or respiratory system or even an infection. A check in with the vet wouldn't hurt. If she has any difficultly breathing she needs to go immediately.
