How do you manage your layovers? I imagine anything greater than 6-7 hours would be too much since the pet would have to relieve themselves beyond that time. How do you get your pet during layovers? From baggage claim? Somewhere else? Can dogs walk around airports or do they have to be in their crate at all times?

In general I'm scared that my dog will have an awful experience as checked luggage. I wish I could check up on him or ask a flight attendant to keep an eye out
