So today we went to the vet again, and the vet noticed my sheltie's stomach was swelled, and inflamed, with some liquid coming out. She said she might have to be re-operated on. It might be that the intestine wasn't stitched together well, or that the intestine is sticking to the wall, or another intestine. We called another vet, the one who did her spaying, and she said that it's typical for these symptoms to occur after a surgery like this, and is just part of the recovery progress, but she'd have to see her in person to know for sure. So we have an appointment with that vet today at 3:30 pm. Currently she's on an IV at our regular vet.
We don't really trust the vet who did her emergency surgery. It was just the only vet that was available. I pray if she needs another surgery, she can get it with the vet who did her spaying. Of course, not needing another surgery would be best. So I hope it really is just part of the recovery progress.
Prayers still needed. Thank you everyone for all your support, and kind words. It means so much to me. I wish the best for all of you, and your shelties.
