What are signs of complications from anesthesia that I should watch for as my dog recovers?

I think that the breathing rate is a big one. You want to make sure the dog isn’t having any difficulty or labored breathing. Monitor their activity level. Does the dog respond to you? Are they aware of what's going on? Those would be two big ones that would be a little more obvious than others.

Look for poor appetite, vomiting, and breathing difficulties. However, most of the time, post-anesthesia concerns are related to complications from the procedure performed while the dog was under anesthesia.

Yes, they may not be able to get out of the car or navigate stairs easily. It's ideal to keep them on the floor and under direct supervision. Other pets and children should be calm around them.
