to whine and cry ALOT? He starts to jump and try to go at them, not in an aggressive way at all. He just gets very freaked out. And he starts to whine VERY loud. Is there a way to have him stop doing this? We cant take him anywhere beacuse he always gets hard to control and freaked out when he sees another dog. He has also been darting out the front door, and taking off. We have to chase him for hours! He even jumped out the 2nd story window (through the screen, not the glass) He was perfectly fine, but why is he doing this? We used to be able to let him off his leash and he would not run away, and now I would not dare to let him off, cause he wont come back....Im getting worried. He is not fixed, could this have something to do with it?
