AITA for not feeding and watering enough?

I (25M) live in a rental house with my roommate (38F) and my dog, Loco. Loco naturally stays with me in my room and is a very loved and loving dog I would assume. I brought him up from Texas to Colorado at the end of 2024 and had been feeding him about a mason jar of food everyday, with double that on the weekends. About mid February, I had kept getting comments about how big he is for his weight and sure enough, his first visit to the vet here, the tech said he was about 5lbs over his breeds max weight (staffordshire terrier -35lbs). So the vet suggested to feed him half a jar a day instead and take him out for about 1-2 hours a day. I did this for a few months and he lost about 10lbs and was a lot more fit and seemed a bit more active.

Fast forward to September, my current roommate moves in and she loves my dog. She has no issues with how I play, feed, or take care of him. All is good and there is no bad blood between us. 2 weeks before thanksgiving, I asked her if she could watch him for about 4-5 days because I was flying out to see my family back in Texas. She agrees and I tell her everything he needs and what my routine is with him. I leave, come back, and everything is still fine between us.

When I did come back, I noticed his food was low and got some more for him but forgot to take it out of the car. It was already late so I decided to feed the last of his food that day and get the one in the car out the next day when I feed him again. I did just that and went to bed. I then wake up to a text from my roommate saying:

“why are you not feeding and watering your dog. give him to a shelter if you don’t want to provide basic survival needs for an animal. it is excruciating to watch him starve”

To which I explained the situation since I thought maybe she tried to feed him while I was at work. She replied she wasn’t angry or trying to hurt me, but just to express what she saw and that it wouldn’t happen again. This ended up confusing me since I thought of other ways she could’ve expressed this in a more professional manner. AITA?
