I'm trying to optimize my site for mobile, but there is a very large background image that is loading on the mobile site and it doesn't even need to be there. I'd like to hide the image, but can't figure out how to do it and thinking it might not be possible without hiding the entire strip.
This is the page - https://www.dogandcathospital.ca/
The background image shows behind the two boxes that are titled "Stay Well Plans" and "See Your Pet on Petly".
Is there anything I can do about this?
