Rover marks my google calendar as busy during a dog's stay, how do I change this?

Hi,

I have dog staying with me for two weeks. That gets added to my google calendar, which is great, but the problem is in the way it marks it off. Rover add's an event to my calendar for two weeks and marks me as busy for the whole two weeks. I have my google calendar linked to a scheduling app for my work and can NOT be marked as busy for a two week stretch. How do I change it to be marked "free" instead of "busy" for the duration of the dog's stay?

Thanks!
