A term used mostly by gay men to depict something unpleasant, foul, or undesirable. Often replaces words such as stupid, dumb, gay, etc. Ugh, this is so vaginal, I have to work a 9 hour shift today! Those pants are straight up vaginal.
Warning signs such as fear and/or nervousness around other dogs, displays of aggression only under certain circumstances (while on leash, in the presence of food, in the presence of the owner, etc.), or most commonly, over-the-top play behavior can be seen at any stage of the dog's development.
Aggression Toward Strangers. It is natural for a dog to be verbally aggressive (to some degree) toward true strangers, those who may come to your home to sell you something for example... and having your Pomeranian alert you to these types of strangers is not necessarily a bad thing.
