Hi , I had my female Blossom spayed and I had her cherry eye fixed at the same time. I'm not familiar with nose surgery, but can give you advice for surgery in general. I also picked Blossom up the same night, as the surgery, the vet advised to feed half of the regular food that night, and then the next morning she had her regular feeding. I kept her in the crate, most of the time the first couple of days, as I have her brother too , and didn't want them playing rough with each other, but since you have only one, you may be able to leave the crate door open and be okay. The only thing is the vet told us not to let her run too much, or to jump, but she was on pain meds for 5 days, and she was full of beans. It was hard to keep her quiet. She jumped off the couch the very first night. Our vet sent us home with 5 days of pain medications, but she only needed 4. She's not supposed to run or jump for a week after surgery, or long walks. I just took Blossom out in the backyard to do her duties, and kept her on the leash, so she wouldn't run around, and jump. After a week you can go back to regular walks, and this is when the vet saw her ack for a follow up checkup, and removed the 2 stitches she had. The rest were dissolving stitches. She will act completely normal gift away, Blossom wanted to play, and run around the same night, but I had to keep her quiet. Just give her the pain meds, give her extra TLC, I let Blosssom lay beside me on the couch, keep her as quiet as best you can, and limit her walks to just going out for her duties. As for tips on how not to panic, I'm sorry I can't help you there , we're going to worry about our babies, all we an do is have trust in our vets, and know they're in good hands. Hope this helps you, and eases your mind a little. Hope all goes well, keep us posted after the surgery, and let us know how she's doing after. Don't worry too much, she'll be fine.
