There are many different breeds available here, some of the breeders are reputable and responsible.
If you know which breed you are looking for you can get in contact with them (some do have even websites). There are good dogs here, but a problem is that for many breeds the breeding stock is small and excessive inbreeding occurs. Another thing is, that dogs here are mostly conforming to US taste/standard and tend to look a bit odd to Europeans.
Also, the mutts here are very good dogs, they often do look nice, they are very intelligent and thankful for a good home. They are very good watchdogs and unless you really can't live without a specific breed, it is a great thing to adopt a dog here (or two for that matter

).
So the bottom line: if you are set on a certain breed, you might want to think about bringing a puppy with you, if not, plenty of choice here.
