Hello all!

I was walking this adorable lab puppy twice a week for close to a month, then his owner told me she was going away for a week and would let me know when she needed me again. After the second week with no response, I reached out to her to see if all was okay. Still no response. I let it go and figured she would contact me eventually. When I sent her that message, it was on an old message, so I thought she may never have received it. So a week ago I sent her a new request because I still have her apartment key, but she still hasn't responded.

What am I supposed to do?
