I visited my in-laws over the holiday break. They have 2 border collies (and really shouldn't but that's a whole nother other...). Both border collies absolutely lose it barking and aggressively posturing when anyone but MIL/FIL enter a room they are in, UNLESS MIL/FIL are not home. Then they can't be bothered to even sit up from where they are napping.

I find this behavior really confusing. It appears the dogs are ?protecting? my in-laws, and that in-laws have somehow unwittingly trained them to do so?

After they're done barking they're affectionate and playful. I'd love to find a way to encourage the dogs to skip straight to the petting/play time.

Thoughts? Advice?

thanks in advance Tildes!
