My 7 month old GSP was doing well with recall and going off the lead quite a bit. Because of him running off to greet dogs (a little to entusiastically for many of the dogs and their owners) I've had to start keeping him perminantley on his lead. I tried treats, toys, throwing a ball, squeaky toys etc to get his attention away from the distraction. Sometimes something would work once or twice but then he seemed to blank me completely. He's been kept on leash for a couple of weeks now while I try and work on him walking to heel and recall training on a long line. When he gets on his long line now he seems to resent any attempt I make to control him. He'll sit and stay and even lay down for a few minutes until I call him at home, infact appart from the odd theft of socks, food etc he is very well behaved at home. Also on his short lead he'll sit and watch me and lay down. But on his long line he'll ignore me. I play ball with him getting him to bring a ball to me then I'll throw a second once he's dropped the first. He just gets bored after three or four throws and stands looking around at anything but me. Today I had him in the lake on a long line. Just as I put him back on his short lead a man came along with an older GSP off his lead. I was talking to the man and he said why don't I let my pup have a play off lead with his dog. He was surprised I wasn't letting him off and said the longer I leave it the harder it will be. Luke was going nuts watching the other dog running in and out of the lake fetching his ball and I felt awful, so I gave in and let him go and play. Luke was running around with the other dog like an idiot, sticking right by the dogs side every second (swimming fantastically). when he got tired of swimming he stood and waited for the dog to come to the edge. Then a couple walk past behind us with two dogs on leads and Luke made a b line for them. I called him back but as usually he totally blanked me. The man said something about his dog being nasty and the man I'd been talking to managed to grab Luke away from them. Luke ran back to the lake and it took a few seconds for me to finally grab hold of him and get him on his lead. Walking away luke was a nightmare trying to pull back to the lake and the other dog and it took a good couple of minutes and a bit of distance to get him back focused on me and to stop him pulling on his lead. I wish now I'd stuck to my guns and not let him off. I've been hoping that by making him walk to heal when we are out and not allowing him to get excited around dogs would help him get calmer and more focused. His brother who was as bouncy as Luke has calmed right down and is more interested in fetching balls than running after dogs. When they get close together now Max is not that interested while Luke wants to jump all over him. I'm starting to doubt that I will ever train my dog, he's my first dog and I wanted so much to be a good dog owner but I feel like a total failure. I'm writing all this hoping someone can offer some hope that I can get my dog focused on me and not every discration in the park.
