Animals learn from each other, even from one species to the next.
I've seen sparrows & doves go after sunflowers when they never bothered them before, they must have learned from the goldfinches and cardinals. Squirrels too, didn't seem to know the red ones were edible until year 2 of planting them.

Dogs "talk" to each other. They can learn both good and bad behaviors from one another.
Thankful my boy dog hasn't figured out how to open the back screen door like our old girl does. She taught him to be afraid of rain tho- he was fine with going out in it before she passed on her fear >:[]

Try talking to it..

They communicate, yes, just like humans do, although not in such a complex fashion.

Crows pass down that kind behavior through generations.

Interesting!

I find that interesting, we all give off odors, signals, non-verbal vibes and I suspect just like with people we meet sometimes there someone I meet and right from jumb I don't really like them bu teveryone else has no problem with the person. I guess that dog just doesn't like your scent would be my guess. Being barked at is annoying tho.

That is just typical dog behavior and I doubt is any indication of "communication". (IMHO)

Last night females were discussing how male dogs seems to want to give love and appreciate their masters while female dogs want to receive love from their masters and act jealous all the time. I looked at them and bite my tongue hard as I walked away because that is exactly how us men felt about them and I was the only one in the place without a mate or a master/mistress by the way to stop me from being an ass.
