I know nothing about Airdales.

We have a Plott Hound and an American Pit Bull Terrier.
Here in Downtown Oakland, there hasn't been a two-legged *anything* yet to cross our fence line.
Pretty much everything four-legged that's hit the turf out there has been shredded (although we have and have had other *family animals* that they've left alone).

The dogs are both wonderful animals, but we don't leave them indoors much with the kids (2 and 4 years old this week) unless we're there to supervise.

They're an excellent BS indicator. As well as cats, opossum, other dogs, coon... they completely blow up whenever anyone of seemingly questionable character makes it into the neighborhood.
They've made a good difference around what will/will not tread near our place.

Both dogs keep clean and don't stink at all even when wet. We feed them good quality food and don't let them get into people food or trash.
The Plott is an amazing bear hunting dog. He helped me get my Black Bear last season I hunted.

Cheers
Tinker
