Owner left out issue with dog, cancelled booking with no payment?

So i was asked by a client to walk her dog for 3 days, i had met up with the owner and the dog was super friendly and there was no issues stated with the dog at all during the meet and greet process. Fast forward 2 days ago, i go to the owners house where she mentioned her mom was staying there to keep an eye on the dog, however her mother was old and had bad knees so she couldn't walk the dog frequently. I go in and get the dog and the dog will not move. I get a message from the owner of instructions for her dog and one thing at the bottom of it all was "If she does not walk with you, coax her into walking with treats or words of encouragement".

Keep in mind, this wasn't a warning ahead of time of the possibility that the dog will not even walk with me. As soon as i leave the house sure enough the dog refuses to move and begins shaking and whining. I do as the owner asks to coax her but nothing is working. She comes up with the idea of letting her mom walk with me, which gets the dog going. Now im a bit frustrated because 1. i was not told this would be an issue ahead of time and 2. i feel bad for the mother as she was not there to do that task, i was, but the dog refused to move and only felt safe with the owners mom.

Fast forward to today, the owner comes up with the idea to have her mom leave the house so the dog would know she is by herself and im responsible for her. I agree and go ahead with that, but the issue then came to, her mom isn't fluid in english, and said the leash was left on the washing machine, i go and look and it isn't there, but by now her mother had left and i didn't have her number to even contact her, nor can i find another leash. Now i get frustrated and contact the owner about the situation. She calls her mom and she comes back and showed me where it was (it was on a shelf nearby, but in a white bag so it wasn't findable) the dog now seeing the owners mom won't move again unless she joins us, so she joins. I yet again feel bad because her mother is having a hard time walking and this could've been avoided entirely. Cut to later today, the owner cancels the last day of walking, but canceled the whole booking all together and now i don't get paid for the days i went and walked the dog. Despite the issue with getting the dog to move, she did and we walked for the half hour requested and she did her business. What exactly do i do? i feel as if i got ... (more)
