Riley the dog is a bit of an adrenaline junkie.
How do we know this?
Because he followed his owner into an airplane... and then followed his owner out of that airplane before it landed!!
Doggy Dental Hygiene: Cleanings
"When having your pet's teeth professionally cleaned, expect more than merely a simple process akin to a tooth version of a car wash and detail. While under anesthesia for the cleaning, request dental radiographs (X-rays).
Without the addition of this important oral diagnostic test, the veterinary professional will be unable to assess the bone level around the teeth; an important criteria in determining a tooth's periodontal disease status and what treatment beyond cleaning is necessary (e.g., periodontal surgery or extractions)."
