My sister,nearly 4 years ago, bought a black and tan Shiba Inu puppy from a pet store. The dog, named Puck, is a strictly one person dog, liking me over my sister and her husband. Well my sister got tired of the dog and gave him to me and heck I don't mind one bit. Problem, the dog barks at everything and runs off at the first scent he catches. In order to correct that I talk him for roughly 3 1/3 mile walks every day weather allowing. Puck also pulls harder on the leash that any dog I know of, even with a choke chain! At the end of the walk he is still full of energy.The dog knows his basic sit and lay down commands but anything other than that he grows bored and ignores me. Can anyone help me? Is there another way to curb his hunting instinct and pulling? Or is he a lost cause as my sister has always said. I refuse to give up on him but I also don't have a ton of money to have the dog trained by a professional. Please, someone help me!
