This is a bit similar to a thread from a few days ago but slightly different situation.
I’ve had a rescue lab x staffie for about a year, he is quite fear aggressive around other dogs. We’ve taken him to obedience classes which he was fine with as the other dogs were on leads/a few metres away from him, and he is much better at walking past dogs in the street since we’ve been counter conditioning.
The problem is when off lead dogs approach him (he is always on a lead). We try to walk in quiet areas and avoid dogs when we see them, and call to the other owners asking them to call their dogs back. It’s fine most of the time, but sometimes dogs approach anyway (grrrr). When dogs get in his space he lies down, growls, whines, lunges, snaps and we pull him away by the lead. Once he was approached by 3 smaller dogs and lunged towards them and I dropped the lead and tripped (was standing on uneven surface). I didn’t really see what happened but he was off lead with them and was either snapping or trying to pin one down or just sniffing-he didn’t bite and I think he would have had time if I didn’t grab him. Another time a dog approached and they had a scuffle-but again no dog cried out in pain and there was no actual biting (my dog had saliva on his neck)-I’m not sure if he could have managed a bite if he hadn’t been pulled away. He’s 9 and had 1 owner before us and no history of biting, and was at the rescue centre for 2 months where he was walked in battersea park and apparently met dogs sometimes and snapped at off lead dogs but never bit. When we’d had him a couple of weeks he bit my husband (redirected and broke the skin) when he pulled him away from a dog in the dark. This was understandable and just down to fear.
Whenever a dog approaches I’m scared he will bite And he is quite a powerful dog, so I always shorten the lead and walk as far in the opposite direction as I can. Sometimes he is lying down so I end up dragging him. When dogs are this close he ignores treats. Sometimes he doesn’t lie down or growl just stares at them so I wonder if he’s just curious and I’m making him think it’s something to be scared of when I tighten the lead and dive into a bush. Should I loosen the lead or drop it (it’s normally a long line and we are in a field). People often say that their dog is much less aggressive off lead/is only leash reactive but I don’t know if this is the case with mine. He has met friends/dog trainers dogs by carefully introducing them after parallel walking for a few mins until he’s calmed down, so I don’t know if he’d just greet dogs calmly off lead/on a loose long line but I don’t want to test this theory in case he does end up attacking a dog. We’ve muzzled him a few times but the rescue centre never recommended it and even after introducing it slowly and positively he doesn’t like wearing it and it seems to make him more anxious-and I’m concerned he could still hurt a tiny dog.
This is long-but basically my question is does anyone have any suggestions of the best way to handle a friendly off lead dog approaching my fear aggressive on lead dog?
