Yeah, it is tough, isn't it? Mine is the same way, on a leash he is way less reliable, he used to be nutz. Sometimes he still is, but now, less often and less nutz. Another thing that helped my Buddy, was his dog class, He took "Basic Manners" He already knew everything on their list, BUT, i wanted an opportunity to practice keeping him calm around other dogs. EDIT: i probably should throw in here, THE FIRST CLASS WAS A NIGHTMARE!!! Okay, so was the second...and the third...:msngiggle: okay, the fourth wasn't what most folks would call "really good" either...but i ws beginning to spot some improvements by then, Buddy had realized, "i come here, i see other dogs, i leave all in one piece anyway." He did get SOOoo much better, no, not great, but WAY better. Everyone said so, too. At first, everyone in class kinda looked at us with mild disdain, like what a loser pair, lunging dog + loser dumb owner who had a dog like that--can't you control your dog or what? But it was cool, over time, they grew very fond of Buddy, and realized lil ol Buddy is doing the best he can. They sorta were rooting for him to get better, and they celebrated with me at his progress. He did come a long way in there with all those other dogs around, maybe he never experienced being calm by other dogs before. Even if only for moments at a time, at first. I'd sit with Buddy, off to the side, and fed him treats, sometimes "speed-feeding" treats, if he was calm, and to keep him calm... trying to teach him: "other dogs = treats for me IF i don't lose my mind.." And oh, i brought him in there reeally hungry, too, and had his favorite super delish treats. I learned a lot, too, ways to distract him. Can't remember now if i learned this next remark i told myself often, was it here on this web or from the school, but you don't wanna let him "spend much time in that state of mind." That was one of the many advice i kept tellling myself to distract him early on, before he escalates. I learned to stay calm when my dog is lunging--HOnestly, i felt a wave of compassion for my dog when he lunged, like i do with sick people, i let that reaction grow in me more each lunge, it helped me speak calmly to him, as i would to somene who is suffering.... and i learned to get him to return his att'n to me, and to be sure when Buddy does put his att'n back on to me, it is a calm and understanding human he is looking at....and reward that att''n on me. No, i'm not perfect at this, but, i'm way way better. I got a LOT of practice, ha ha!! If 2 or 3 blocks is his limit, well, that is his current limit. With time, you can probably reduce the 2 or 3 blocks to 1 or 2 blocks, and so on...takes a lotta time, it does. But it is worth it. So worth it. Be sure you read the info i was given here, this website helped me with Buddy more than anything else did, these folks, i don't know where me and Buddy would be without their help. The fence work is good, esp since you have bad back, is good chance. you can actually sit next to your dog, and get him calm, and reward that, i did that too. It's super crucial to nip it in the bud, at first signs of Bender starting to react, distract him THEN, right then, reward, i mean REEALLY reward that turn of his head to you. I used to do this out in our front yard at dog-walk hour. I'd sit out there, right next to Buddy on leash, some distance back in yard, and when dogs went by, i'd speed-feed treats, one per second, while dogs went by. This might work for you with your bad back. We did this a lot. Ha, most of the dog walkers thought we were nutz at first, but they figured it out, and sometimes they'd go by twice for more practice for Buddy. Over time, we moved a lil closer to the street, and so on. If Buddy was being reeeally good, he got to go meet dogs going by if it was ok and all. If you can only distract him for a moment at first, well, that is a start. it gets easier, the more you practice doing it, and easier for the dog, too, the more he gets the hang of, "Oh, mom wants me to look at her instead of going completly outa my mind? Okay, just 1 peek at mom then." Practice having him "look at me" inside your house. Let Bender know when he does BIG TREATS! HUGE PRAISE! best moment of his day!! Then out in the yard. And progress to very mild stressors, reward ANY teeny lil glance at you, any sign he is calm. and then take him away. ha ha! Buddy now looks at me even before i say it sometimes. To Buddy--"Scary dog = I gotta look at my mom. I bet she wants to shake paw, too..." It snaps them outa their focus on the other dog. Hopefully, someone smarter than me will spot you and give you some pointers and stuff. HANG IN THERE, AND KEEP US POSTED!!
