I cancelled the 2nd day with a puppy because he was not house trained, do I modify the payment?

I would call support @ [Edit: Rover’s contact options have changed. Visit the Rover Help Center at https://support.rover.com/ to find the phone number, help articles, or chat with the team] to cancel the day and refund the client

PUPPIES WILL ALWAYS HAVE ACCIDENTS. You should know that if you want to work with dogs. That's like babysitting babies and being angry they pee in their diapers..

You do not modify nothing, you call Rover and explain what happened, and they will fix it for you.

Puppies, and even full-grown dogs, will often have accidents in a new environment, especially when they're under stress and trying to get set up on a new potty routine. I would steer clear of puppies especially if you don't have a carpet-free area in your rental that they could hang out in if they're having trouble. Or, you need to be extremely attentive to their potty needs and give a potty break 10 minutes after every time they drink water, immediately whenever they wake up from a nap, after each play session, etc.

If the stay is still active, you can click "Modify" and send Rover a message detailing what you'd like to do. They are very quick and super helpful. If that option isn't there anymore, you have to call them or go through their "Contact Us" link at the bottom of the homepage, then click "Contact Support" at the bottom, which brings you to this link: https://support.rover.com/hc/en-us/re... They are extremely fast at getting back to these support requests. I almost always get same-day responses. I think they try to keep the phone line for more urgent issues.
