<human>: Could you distill the essence of the text into 1-3 sentences?

My girlfriend has two papillons, one around the age of 5 which she purchased when the dog was less than a year old. The other is a show papillon around 2 years old that her parents bought just a month or two ago. She currently lives with her parents, so these two Devils live in the same house. 

Neither her or her parents have put more than a days effort into trying to train either of them. 

Ever since I've known her, the eldest dog has completely lost his mind every time someone opens a door, or closes a door on the opposite side of the dog. Very recently, he's been nipping at your ankles as you're trying to leave the house. Usually, he will just rush at you barking and growling fiercely until the door is shut. But the new development of actual biting is what kind of threw me over the edge. (It's been an everlasting battle regardless...). He will also bark endlessly every time the A/C clicks on until you tell him to hush. Besides the constant barking, he's a very sweet dog and will get along with everyone as long as you let him sniff your hand or throw a toy for him at least once. 

The new papillon, the show dog, has over the course of time adopted these same symptoms but turned out worse. Where the older dog will generally only bark when anyone touches the front door or bedroom doors, the younger dog will now rush at you and bark and growl regardless of what door you're opening/closing. Opening the bathroom door and stepping out is a serious offense to this little guy... 

Everyone in her house has mixed feelings about how you train a dog, and completely lacks the motivation to even begin training. We're all very tired of dealing with these issues, and nobody (including myself) has a clear idea of where to begin. 

Can somebody please help us? This madness needs to stop. Its making everyone extremely stressed, and we desperately need to know how to fix this.

Sorry if this seemed passive aggressive... It's been depressing knowing that these dogs have so much potential to be so amazing, but they're in the wrong hands.
<bot>: two papillons bark and growl at anyone who opens or closes a door no matter the time frame, and one recently started nipping at ankles during those fits.
