Me, personally I would have not been listening to the dogs barking for 6 hours … and certainly two days in a row. I would probably gone in the unit after 20min and put an anti bark collar on the puppy … or taken him in with me.
Read through this post. Perhaps calling Animal control is a bit krass, but a message mentioning it would get the point across nicely.
My beef with your suddenly appearing fine print lays more with the crating …I would certainly resent that and probably seek a cancellation as a guest.
