Pet's info: Dog | Australian Shepherd | Female | spayed | 44 lbs
My dog is terrified of the fireworks and won't urinate. She can't even focus on urination. It has been about 12 hours and since it's the evening, the fireworks began again so she is refusing to go outside. If she doesn't pee tonight, can she get sick? How long can she go without peeing? Will she go when she really needs to or will she keep holding it? Thanks for the info.

I'm so sorry that Chester had a rough day yesterday. Most dogs can withhold urine for up to 18 hours if they are determined enough. This is not ideal and can increase the risk of urinary tract infections and even potential damage to the ability of the bladder to contract and fully empty. However, both of those issues are problems we would only worry about if this was an ongoing issue for many days; as apposed to just holding it that long once or twice.
I hope that helps you! Thank you for using Petco Pet Education Center, formerly Petcoach!

It sounds like your pup was very scared of the fireworks, which is causing her to urinate on the floor. Since the 4th has passed, she may start to calm down on her own over time, however if it's been several days and she is refusing to eat at all or move at all, a visit to your vet ASAP is best to rule out any health issues.
When fireworks are happening, making sure to take her out before/after the fireworks, and providing a place she can hide during them such as in a dark bathroom with soothing music playing to drown out the noise can help. Your vet can also provide you with anxiety meds that can help during high stress times such as this.
