I have recently adopted pete an almost now 9 month old am staff/bull terrier mix or so we think. He has very high energy and hell be standing one minute and the next jumping back at his back side like something is attacking him. he will even lunge at his tail and chew on it alittle then he looks at both side like somethings going to get him. i have heard just to leave him that if i comfort him i am just egging on the behavior but i dont want him to be crazy! just not sure how to handle. plus im in Minnesota and looking for a trainer only had one class. it wasnt quite what i had wanted, i want more than the basic sit stay which we still dont do. if any one knows i would be so happy.
