Wondering if i can pick the brains of other reactive dog owners or anyone experienced in training really?!
So, reactive GSD. Never bitten but typical lunging barking mess when out. Frightened of life and 'diagnosed' by a behaviourist as fear aggressive. He runs up to dogs or people and barks/snaps at them if he does not know them. He is friendly once he knows the person or dog is no threat.
Anyway we have been doing lots of positive training, treats when we see other dogs etc following a training programme set by behaviourist a few months back.
We also have been attending a group walk once a week with many different dogs. Every week there are different or new dogs and it is not ran by my trainer but by a rescue organisation. It's basically a free for all, turn up let dogs run wild and go home.
In all honesty he has been brilliant and is very submissive and non reactive when off lead, except nipping other dogs when they run (or trying too-he is always muzzled!)
He has never been in any real trouble there and seems to just do his own thing really. Other dogs have fought but thankfully not mine!
However Day to day his training has stalled and I am still struggling with the reactivity every single time I leave the house with him.
I am wondering if this sort of group walk type thing is actually bad for him? He has been 'told off' a few times by other dogs as he has no manners and I'm not sure if this is setting him back? Last week there was also a bad fight between two dogs and it's scared me as if it was him he would have curled up into a ball and been torn apart, he wouldn't defend himself and is muzzled so couldn't anyway 
Is it safer to just avoid interaction altogether rather than risking him getting a fright and being back to square one?
I suppose the fight has made me question whether letting him interact with 15 strange dogs a week is actually making him more frightened? He seems okay at the time but I've read they can shut down and actually appear to be okay when they really aren't?
