None of mine were supporters of BLM. Or meter readers.Mine has this animosity toward Mexican Gardeners.... I'm pretty sure she can smell illegal... True fact. I only say that because a several times now there was a clearly a white dude Gardener walking or working within a couple feet of us as we walked... and she never gave them a second thought. Yet in every case she sees a Mexican Gardener from about 10 feet and she hunches down ready to lunge.
My black lab mix was human smart. Workman could bring their tools onto the property but he didn't allow anything to be removed.
I'd have to put him up before they left with their own equipment otherwise he wouldn't allow it. He would have bit.
He did stop one actual burglary.
