I actually do pet sitting for a few clients. I charge $20 to $25 per day to go at least 1 time a day Usually 2 times a day. To feed, play and clean up after the pets.
For their dog, we have discovered their dog likes going to the boarder. He gets so much attention there, and he gets very lonely at their home if no one is there.
The 2 huge cats, like to stay in the house. So generally, I go there at least i hour a day usually 2 times. to play, feed, and clean up after the cats.
The family tells us, we are welcome to stay longer and watch TV.. etc..
Our other client pays our daughter to actually stay at their home with their pets. They have 2 dogs, fish, cats and usually a lizard or turtle. One time she had to feed frozen blood worms to one reptile.. It was pretty gross.
I would make sure any people you will be staying with, need to be 100% ok with your dog staying at their home. Our house for instance is not set up for a dog. Our fence is not secure enough, and there is not much room in the house, for tail wagging if it were a medium to large dog.
