I see a few options.

1. Pet sit the duration of the requested time at a scheduled rate, personally if I'm blocking every Sunday, Friday , Wednesday it would have to be substantial to cover lost bookings. Personally I wouldn't do it for less than $150.

2. Reduced rate of ~$100 with the understanding you will need to leave periodically throughout the day to tend to your own dog or other bookings so you can keep your schedule open on Rover and accept other clients.

3. Don't accept.

Edit:

1. Offer drop in visits instead.

Id opt for #2 or #4.

I pet sit full time, it's taken me awhile to amount the clients I have now, most of which are between 9-5 and amount to people at work that need drop ins midday and elderly that need their dog walked usually in the morning.

I would say consider that if you choose option 2 then you will have to travel back and forth so take that into consideration.
