Dennis, The panels you referred to are different than the existing 584A, the current item is 584B, it is a different panel than 1774, indicated by the item number.

I would like to try to order the right ones. the 584 B does not show that what is the item number that I need?

It's likely listed as 584, suffixes are not usually listed on the site.

How can I find out what style tile we have at our Animal Hospital?

Look on the backside of the tile, the sku or style no. usually is located there.
