Well I decided to decline and not sit for the two dogs.
Although I could use the extra money I just think it'll be way too much. Two extra ones are alot and the owner doesn't gate them or anything. I think I would have issues there. Plus they are older dogs and I would just be so worried about them! I guess he also home cooks for them. (there is no way I can do this!!!)
So I decided to pass this time. Thanks everyone for your input and price suggestions. At least I now have an idea on what to charge!
Thanks!!!
