Too bad they don't make something like this only a bit bigger. This would be soooo easy to set up!

Those dog kennels I linked to look pretty easy! They say you only need pliers and there are no holes to dig or concrete to pour. With such small dogs, you really don't have to worry about them chewing through and knocking it over either!

They sell a rain/sun proof roof to fit over the top too!

There's a guy near us who breeds dachsunds (at least I think he does when I see about a dozen there...). He has two crate/kennels in the front yard. Seems like something like that would work for your dogs. I'd be concerned that, if you leave them outside they could get out of the rain and sun. But that would be less expensive than a larger fence.

We're still going back and forth between the invisible dog fencing and a regular fence. I don't trust the invisible fence while we're not at home.
