Not really, two of them would barely be able to move in one of those and it's too small to allow them to get away from their toileting. If you don't have any panels or something that you could make a pen with, do you have a small room that you could shut them in, like a WC, porch or the bathroom? If you really don't have anywhere to put them, maybe the vets could keep them overnight to check that they are ok before bringing them back the following morning?
I'm sure they'll be fine
I actually come think ofitbhavea lab sized dog crate, i thnk thry will be ok in that
unfortunatly one of them is too small! so they are re booked for wed 19th january.
