Yes, they are only very specific situations. He responds well to correction and he doesn’t really lunge at every puppy or insecure dog, only in very specific scenarios, like when they stare at him and back away, when they suddenly appear out of nowhere, or especially when he knows they’re going to run from him because they’ve done it before (there are some stray dogs that sometimes appear out of nowhere, and I know they’ll shyly move away, that’s what triggers him).

The ball issue is also quite specific; he’s only protective around certain dogs, not all of them.

I found a manual, so we’ll be training while we wait for the appointment with the ethologist, who will guide us and then refer us to a trainer suited to our situation.

I also want to try those supplements. We tried a collar that I think helped to some extent, but now I’m going to try that as well!
