I used to work at an animal rescue shelter called ARF (Animal Rescue Foundation) located in Walnut Creek, CA as a teen volunteer during high school years. I was assigned to facility management and sanitization as well as socialization visits to a particular assigned condo of 1 dog or more by my superiors and approached them based on instructions and notes left on their condo door before entering inside. In addition, I've worked for a similar dog/pet sitting job system like Rover here under another system called WAG! Walker. I've done many dog sitting jobs under WAG! and I've received a lot of great ratings and bonuses from my clients because of thoroughly followed protocol under their instructions plus providing absolute 100% care for their dogs and providing them full in-depth reports on the shift in regards to their behavior and how the day went with them.
