If your dog has preexisting conditions DO NOT use Rover. All of their Rovers (the name of a petsitter) are protected by their Rover Guarantee, meaning if your pet has meds and needs all they have to say is it wasn't the Rovers fault. However, as responsible pet owners you know your pet and when they come back to you unable to walk and within 2 hours after being returned to you are admitted to the ICU, skipping a 16 hour wait list, you know neglect happened. Make sure you take videos of your pet's condition before releasing them into the care of a Rover. Call Rover and ask them how to become a Rover, it requires a background check, 3 letters of pet care recommendations and that's it. No site visits, no interviews, nothing. Rover is an Uber for pet care, avoid using if you love your pet.
