My dog (male chocolate labrador, 6 years old) had dental cleaning under full anesthesia a few hours ago. The ventilation tube the veterinarian tried to insert at first probably didn't enter well so he removed it and tried with a different one, after which he said that "now I'm 1,000% sure it's placed correctly" to assert he's only working with certainty.
So my dog is still a bit restless and whined a bit earlier, and I thought it might sound like he's wheezing very slightly, so I looked at his gums and inside of lips and I'm not sure if this color might be indicative of hypoxia or that it might be related to the cleaning process. I don't remember how his gums usually look to compare.
Thank you in advance.
EDIT: I will just update that I also sent the pictures to the vet just to be sure, and after an hour when he'd yet to reply I called him just so he would confirm if it's OK. After I said that online resources say dark spotty gums could be indicative of hypoxia, his reply was simply "ah? What? Stop bothering your dog, bye". What an unassuring way to treat a patient/customer (who's just paid $350 for the procedure).
