Last year I went to my girlfriends house and watched her home and their two dogs for 6 days. She paid me $500. I was NOT expecting $500 - but she felt that I LOVED her dogs and took care of them like they were my own.
Call the kennel and find out what you would pay at the kennel and then pay her that. Maybe more if you can find it. She's taking care of a puppy - is he house trained? If not - then she'll be cleaning up after him as well.
When I had someone take care of my kids in 2006 - I paid her $400 for the week and that's my kids...
Do what you can afford...
