owner’s strict expectations

So I am dog-sitting for this owner and we went over all the rules she has and everything before I started watching her dog. I asked her how long he can be by himself without me. She told me 4 hours. So I have been making trips. I hang out with the dog for a little bit, let him outside to go potty, throw his toys, etc. Then I’ll leave for NO MORE than 4 hours. Usually three. Come back, repeat. I also stay the night at her house as well. (My sister is also visiting this weekend, so I try not to spend 24/7 at the house with the dog obviously.) I haven’t broken her rules of being gone for more than 4 hours, and yet she texts me saying “I want to make sure you’re staying at the house. I’m watching the cameras and seeing you coming and going for a couple hours. The idea was you were staying at our house with him because he likes to be with people.” I have been hanging out with him but does she just expect me to be on house arrest with her dog for 10 days? I don’t really understand. I just feel like she is just checking the cameras every second of every day she’s gone to see when I’m there and when I leave and I just feel super under control and monitored. I also live 5 mins away so it shouldn’t be this huge deal. She didn’t tell me I have to be with him all the time so i’m just wondering if this is on me? It’s just a lot on top of all of her ridiculous rules about this dog . She told me he sleeps in a different room at night and yet he won’t stop barking for HOURS when I try to put him to bed unless I bring him in my room to sleep with me. [I should add I am literally getting paid $50 a day lmfao]
