Blueoctgal how has your trainer been having you use the Ecollar? How did you introduce it?
What makes the GSD go after a dog on leash is prey drive. Your dog must always be on a leash if you live in an urban or suburban area -- and nearly all have leash laws. It's very irresponsible to risk putting other people's pets in danger. Please make peace with the fact that your dog must be leashed--not just for the foreseeable future, but always.
I think that it's rare that prey drive is involved in dog to dog aggression. Mostly it's fear related, not prey related.
ANY dog can be trained to work off leash if the right methods are applied properly. In many "urban or suburban"
environments, it's appropriate to have a dog off leash. Even if you don't plan on ever letting a dog off leash, his recall should be reliable because accidents happen. Dogs bolt through doors, they pull collars over their heads and out of their owner's hands. They escape from back yards. Sometimes equipment breaks. EVERY dog should be trained to have a reliable recall and a reliable stationary command that he'll obey at a distance, no matter what distractions are present.
There is ABSOLUTELY no reason that EVERY DOG cannot have a reliable recall, except that it's owner is not willing to put in the work!
I'm not 100% sure if chasing cars is a prey drive thing. I think of prey as small, something to be eaten, I don't believe any dog out there thinks they're going to eat a car.
There is "small animal prey drive," which you refer to, and "large animal prey drive" which involves larger prey, such as a man, deer, etc., and yes, perhaps cars.
Your dog could care less that the other dog is on a leash. It actually makes that dog an easier target since that dog can't get away. It's the same reason why some dogs are leash aggressive...they are in fear because they know that flight is not an option so the only other option is fight. You really need to not rush your dog, get him back on a regular leash and work on LAT and getting obedience extremely reliable.
I’m not sure what LAT is either. I agree that you need to work until your OB is "extremely reliable."
The dog should obey every command, without it needing to be repeated, no matter how far the dog is from you, (allowing, of course for him to hear, see, or feel the command), and no matter what distractions are present.
He has been great with recall at the beach - even with lots of distraction that's why it just got me that he kept going last night and at such a good, submissive - therapy in training young dog!
Not sure what "good submissive – therapy"
means. Can you explain please?
That's how I got my Aussie. He was not trustworthy off leash - his previous owner shipped him out (no trainers in this area) for expensive training - the trainer used an e-collar with no success - he finally told her he had never met such a stubborn dog.
Any trainer who tells you that a dog is "stubborn"
is not worthy of the title "TRAINER." Dogs aren't stubborn, that implies malice, they just have an agenda that is different from ours. DWDWDWD = Dogs Wanna Do What Dogs Wanna Do, is a saying I use to get this point across to owners. Often the things we want the dog to do, work at cross purposes to the instincts that nature put into the dog. When this happens we need to show the dog why it's in his best interest to do things the way that we want. This is pretty easy if you work WITH the dog's drives, rather than against them.
Remember the saying about getting your boss to do something ... make him think that it's his idea! If you can do this with your dog training, you're gold.
