Eftersom ni är så trångsynta och inte förstår att juckandet inte alls behöver betyda stress kan jag citera Sara reuche som håller igång Paws Abilities Dog Training. Så här är några orsaker varför hundarna juckar.
"Arousal
Once a dog hits a certain level of excitement, that energy has to go somewhere. Some dogs express their joy by doing ?zoomies,? where they tuck their butt and sprint as fast as they can in circles. Some bark. Some hump.
Play
Play is interesting. When dogs (or other mammals!) play, they mix up a bunch of behaviors in new sequences. These behaviors have very useful roots: chasing, stalking, and pouncing are useful hunting behaviors; mouthing and wrestling are useful fighting behaviors; and humping is a useful sexual behavior. Some biologists believe that play is practice for the real world. By mixing all of these useful behaviors up with some other signals that mean ?just kidding,? dogs get a chance to practice moving their bodies in ways that could increase their chances of surviving a situation where the behaviors were needed for real.
Status
While this is a common attribution for humping, dogs ALMOST never use humping as a form of status seeking or as a display of status. In fact, in more than ten years of training, I?ve only met one dog who appeared to use humping as a means of status seeking.
It just feels good
Frankly, dogs just like to hump sometimes. All mammals masturbate, and some dogs will hump a favorite toy or pillow. From a behavioral standpoint, there?s no reason not to let Fido or Fifi have a little ?me time? on occasion as long as it?s not causing problems. Two of my dogs, Dobby and Mischief, often hump each other when they are playing, and as long as both dogs are okay with it, I don?t interrupt them. I draw the line at humping people, and if my dogs do this I redirect them and teach them more appropriate ways to interact with humans.
So there you have it. Humping is a normal doggy behavior, albeit a somewhat embarrassing one for those of us on the other end of the leash
