How to attract more puppy customers?

I am a dog hostess (is that what we're calling ourselves, non-travelling sitters?) and have a puppy and am looking for more opportunities to give her puppy playtime when there aren't social groups available. Does anybody have ideas for attracting more puppy customers? I've had zero puppy requests so far. I wonder how common puppy requests are anyways - I imagine most people like to stay with their puppy as much as possible and may feel bad leaving others to care for him/her since they need so much attention. Would it sound weird to say specifically in my profile that we are looking for puppy customers?
