You don’t know that for sure.
When the time comes, they may surprise you.
A few nights ago about 3 AM, the Portuguese Podengo Medio set up the alarm from the cabinet she stands sentinel on in my art studio at the picture window facing south and the Dobe leaped to the east window, barking, too.
I thought maybe the thieves had come back for more of the neighbor’s stuff and let him out the front door.
The thing about Dobes is that they raise hell over intruders when inside but run silent when out.
He made him himself low and ‘invisible’ in the darkness and ran the perimeter several times before reporting back.
He wasn’t agitated when he came back and I didn’t see anything moving so I have no idea what really was out there.
Hubby suggested a cat but although the Dobe will bark at the stray cats, the PPM never does.
As for your dogs, don’t underestimate them.
In 1993, my totally non-aggressive, sweet as honey Ibizan Hound growled and jumped onto the back of my ex who was trying to strangle me to death.
She’d never done such a thing before and never did again.
But when it *counted*, she was there for me.
Your dogs would probably do the same.
Out of my 4 dogs, the only one that I can count on to actually bite an intruder, weighs 15 pounds and is totally blind. But they will all bark like they are going to take you down.
