forever--why would you assume that if someone adopts a dog from SXM, that in the US, they would be in a cage?? Plus, not all of the US is a 'freezing climate". Regardless, I have a friend who lives in Canada, who adopted a coconut retriever from SXM. They do get quite a bit of snow where he lives, by the way. And his dog LOVES the snow. Dogs are quite adaptable.
Maybe it wasn't obvious I was not talking about EVERY dog that leaves SXM. Just in general I would think it safe to assume that not everyone that takes a dog from SXM has a nice big yard and most likely some people do live in condos and apartments and would need to cage them while at work for lots of reasons, which is common and ok. Certainly its a nice thing to rescue these dogs but it seems silly to again assume every dog ends up better off. IMO
