You can't apply for jobs, dog owners who are looking for a sitter or walker will contact you through Rover. However, you can share your profile link on Facebook, Kijiji etc to advertise.

Rover definitely penalizes the sitters by doing this. I recently was sent a warning email from Rover saying that my dog sitting in dog's home service was turned off, had to email them to get it turned back on and they threatened that if I was not booking this service regularly it would be turned off permanently. This despite that fact that in the past few months I have only turned down this service because it was quite far outside of the area I am willing to travel to. If they encourage owners to send messages to multiple sitters even though only one will be booked, the sitters that don't get booked are penalized though they have done nothing wrong.

Yes, I'm getting an error too.
