Here's hoping Ava has a speedy recovery!
I always get nervous when I take a dog to the vet unless it's a well visit.
I was fortunate with Angel. He did not bother his surgery site, did not cry, and was up an about 2 days later! His surgery was like a spay, he had to have to incisions because one testicle didn't descend.
An hour away from the vet - no wonder you're nervous! My vet is only 10 minutes away! I swear, hubby was holding back tears when Angel had his neuter!!
Try to relax, so that she will too!
