I would like to know if you specify the time your service should last?

Every Rover sitter is an independent contractor and we all have different protocols so there isn't one size fits all. Many sitters use the time/hours you mentioned as their standard overnight rate; 8P to 8A. Many also charge for a mid-day walk or visit. Some sitters charge a higher rate to include 24-hour care; it really depends on how you choose to offer your services. Hours of coverage should be discussed with your client at the M&G and an agreement reached on what you will provide and for what rate.

Rover defines house sitting as staying overnight in a client's home and that each "nightly" charge is good for up to 24 hours of care, the same as they receive for boarding their pet.

However, there is a wide range of interpretation among Rover sitters about what constitutes house sitting. Some will move in but also do drop-ins and walks for other dogs using the client's home as a base of operation. Others may only be there from 7 pm to 7 am and have regular full-time jobs. Some will check in on the dog in the middle of the day; some may charge extra for a drop-in visit or walk. So it is always good to clarify with the pet owner exactly what they will receive for your "nightly" charge.

You charge a very low rate IMO for house sitting. I consider it a "premium" service because you are not only watching a pet but also the home and may be asked to do little tasks like taking in the mail, watering plants, etc. A client should be paying much more for you to uproot yourself and move into their home. When you have a higher rate, the daily walks would be included. But since you are only planning on being at the home from 8 pm to 8 am, charging for the additional drop-ins and/or walks would be appropriate if you've gone over how you charge to the client.

Boarding usually would be 24H period (give or take couple hours, depending on how strict you are on your time). Day care would usually be 8H period. I wish Rover would make it easier for sitters to specify that through the app so we don't have to go through this discussion with each client. We have many clients who request to drop off early in the morning and pick up in the evening. In that case, would charge a night boarding and a day care.
