Is this normal???

Preface: I am currently in tech school about to start anesthesia labs in a few months. I just recently started at a new job. I was in surgery monitoring dentals and procedures ( not by myself I had another tech there to oversee everything). When we were getting the animals down, the tech intubated the dogs when they were still blinking and looking around (not moving their head just their eyes) and they were breathing pretty heavily. This is nothing like what I’m used to as at my old clinic the animals were always completely sedate before intubation. They also didn’t preoxygenate any of the patients. The regular prosecutes went relatively normal other wise except for the dentals. Both dentals needed extractions. We got the first dental down and she started getting bradycardic and hypotensive. They have atropine and turned her down to 1 to help (which it did) expected the patient woke up during the dental. Eyes open, coughing, moving, and everything. The tech turned the gas back up and continued with the dental. I didn’t think much of it since there were issues with the HR and BP. However, when we got to the second dental with extractions, the patient woke up AGAIN! I have never seen this happen at my practice during regular procedures or dentals. On top of that while the dog was moving around and blinking the dr was actively prying at the teeth. It seemed like that would hurt to me but I’m not 100% sure what all drugs were used. I know the dentals got ketamine, meloxicam, and I think hydro and also antibiotics SQ. There were no nerve blocks used during the dental. So my question is- Is this ok???? Is it normal??? I have just been at a clinic that sedated heavier than normal???? Any input would be appreciated as I am pretty shaken up after today and questioning staying at this practice.
