Fostering Recommendations

I’m looking into fostering and am wondering if anyone has any recommendations of rescues they’ve worked with in the past. I have always had dogs growing up and love them, ideally I’d adopt one but financially that’s just not in the cards right now, especially as I’m at a point in my life where I’ll likely be moving around quite a bit to explore.

I don’t have any pets and live alone, but do have to be in office every day, and I would feel bad getting high energy breeds / puppies so I’d probably be looking for low energy breeds or senior dogs.

I’m still not sure if I’m going to do it or not because like I said I am in office every day and would feel guilty fostering a dog just to leave it at home but I wanted to explore the possibility.
