Anesthesia can be scary and aspirating is a danger, especially if there isn't a breathing tube inserted during the procedure. The lighter anesthesia used for dentals is supposedly so safe and light, but there's always a danger that this can happen. The best safeguard is to make sure they receive nothing by mouth appx. 12 hrs. before the surgery. Did she accidentally get some water that morning? Thankfully she's ok!!!

Since Kaia was a rescue, perhaps she is a bit older than 5? Still, at age 5 she may have some early arthritic changes on that one side (hip perhaps) or she may have some pre-existing hip dysplasia with arthritis resulting from that. The only way to know for certain would be through an exam and xray. I would suggest calling the vet and maybe getting her checked out, even if you decide against the xray. Perhaps she/he could recommend a glucosamine/chondrotin supplement which has helped many dogs with this problem, including my Cody. There are other anti inflammatories that can be prescirbed such as Etogesic, but are usually prescribed for more severe cases. And light exercise is important to keep her joints limber, but I wouldn't overdo it until your vet gives the ok. I hope it's nothing more serious than a little arthritis. Please check back and let us know how she's doing. And bless you for giving her such a loving and caring forever home!
