Do you give out/withhold affection to modify behavior?
Yes, I do. When I got my dog she was very fearful and skittish. It was very important to give her space, not shower her with affection. We even had a few instances of her snarling and air snapping at strangers who made her feel cornered and were invading her personal space (they were trying to be affectionate, meant no harm, just didn't know better). Now that we've given her some space and some time, she will ask for affection rather than us pushing ourselves on her. She is still shy around DH, but sometimes she will come up to him and lick his face, so we give lots of praise and affection for this b/c that's the type of approach we want. I withhold affection when she is offering fearful behaviors that are dangerous. For example, last night she saw an empty box on a table and for some reason that scared her. She tried to run and hide behind me, but since she was on a linoleum floor, she slipped and crashed, bumping into the table and chairs. This made her even more upset! I turned and backed against the counter so that she could not hide behind me, and I waited a second for her to calm down. I could have let her hide and then coddled her, but what does that say? "ooooo, it's OK! That big bad box made you do this and it's my fault and the boxes fault, we are so sorry." Um, no.
Her reaction to the box is what made her crash and flip out, she did that to herself. Instead, I just said "sit!" and for some reason asking for a sit always redirects her back to reality and snaps her out of it.
Then I said "ooooo, good GIRL!!" and gave her a rub down. At this point, the box fell on the floor in front of her, she sniffed it, and we walked away. Mission accomplished! I also withhold affection (and everything, really, no treats or eye contact) when she is acting fearful of DH. As soon as she makes eye contact or steps towards him, we praise her, pet her, and treat her. If we are out on a walk and something startles her, I will say "It's OK!" just to show her that I'm not scared, I'm still cheerful, but I won't stop and coddle her or let her try to hide behind me
Use affection as a reward?
All of the time! I have a dog that is not food motivated, toy motivated for about 30 second and then bored, so affection is her greatest reward. She is a velcro dog that loves obedience more than all other activities, to praise, affection, and affirmation are what she needs. She has a bad habit of jumping up on me (only me) so instead of yelling "no!" and pushing her off, I ask her to sit and wait, and then ask her to jump on me. Now I can command something she really wants to do. It's a win-win situation. She loves to put her paws on my shoulders so she can lick my face and have me scratch her cheeks. I like doing it too, just not when she's out of control.
Do you believe that showing affection while a dog is reactive or fearful reinforces reactive and fearful behaviors?
Yes, not only do I believe it, I KNOW it is true. This is why my dog is/was fearful and skittish. Something happened to her and her previous family did not understand how to help her. They helped her as they would help a human - coddled her, babied her - and her fearfulness only got worse. Their affection conditioned her fears.
Do you think it's mean to use affection as a means of shaping behaviors?
No, but what I think is mean is only going halfway, only withholding the affection and never giving it. If you withhold something in order to shape behaviors, you have to also give it when it's appropriate. I believe that when doing any sort of training or behavior mod, you have to set up situations where the dog can and will succeed. If you are trying to use flooding and it's not working so the dog never gets affection, that's not fair b/c you did too much too soon and you are making the dog more confused b/c there is no reward to show the dog what behavior is desired. Like I said earlier, when Kenya starts acting nervous, I ignore her, but I don't just leave, I ask her to "sit" and when she does, I praise and give affection. You can't always tell the dog what you don't want, you have to indicate what you DO want. I use withholding affection lure the dog into offering what we do want and then showering her with affection. How much you give or withhold affection will depend on the dog and the circumstance, but I have a very "operant" dog who has been trained using operant conditioning since her birth so it's her nature to offer new behaviors when nothing happens, therefore it works for me to withhold and then give affection b/c I create a situation where I know she will offer the behavior that earns affection. I have worked with other dogs who were physically abused and neglected and with them I have to start a lot simpler, set the bar a lot lower, withhold affection for cowering but then give it the second they make eye contact or give a sniff in my direction. So yeah, I don't think it's mean to use affection for NILF as long as you follow through and set the dog up for success.
I also think that the human motives for showing affection can be too self-satisfying and mean nothing to the dog. As far as the dog's brain is concerned, affection is just another means of
communicating what is right. I praise and pet my dog so often, the neighbors think I'm a nut, but this has been the most effective way of communicating my affirmation.
Of course, there are times when I do give affection for my own selfish reasons. I ask Kenya to come sit on the couch or on the bed. I walk up to her and pet her while she is sleeping. These are things I do b/c I like doing them. I'm not rewarding any particular behavior, other than that if she were to suddenly act fearful, I would stop and find a way to redirect her fear and then reward the result.
What I do think is mean is giving affection based on our own reasoning and not the way that science has proven dogs learn (classical and operant conditioning). It would be mean for me to reward Kenya's fear with more affection. Humans created and conditioned this fear in her, so as a human it's now my responsibility to help her get it own. If I see she is fearful and don't intervene, that's mean. I know how to redirect her (and by redirect I mean I ask for something I
know she will give, NOT poke her neck or jerk on her collar) and snap her out of the fearful state. I know that affection is not the cure. So it would be mean for me to think that it is based on human reasoning.
