I have a dachshund who is 10. We've had an active trainer for the pasdt 8 years. However, Jake has become ho hum about his training recently, so I've been trying for a new take on training. We've started doing tricks. He adores this. I came upon this site because I was looking for a way to teach him to roll over in a blanket. He rolls already, but I'm not sure how to go about getting him to grab the blanket and keep it in his mouth while rolling. Any ideas?
