I would be asking your vet about the possible side effects of those antibiotics, first.
Secondly, in what situations have you used the e-collar to train the dog? When he's barking at something? Perhaps jumping up on your friends or being too excited?
The reason I ask is that sometimes, if you use the e-collar incorrectly, you can unintentionally teach the dog something that you really don't want to. For example, if your dog was happily going over to your neighbor's dog and the neighbor and got zapped by the electric fence....whoops, now he thinks the neighbor and her dog were the ones who caused the shock. He didn't understand that the shock was a result of him reaching the boundary line.
This kind of thing can happen in so many situations, and you really can't predict what the dog is actually learning. Because he's only 1 year old and still pretty much a puppy, I highly doubt that he fully understands exactly what is expected of him in all situations, so when you use that e-collar, it may be that he's accidentally learning that neighbors and friends cause pain when they appear.
That's probably not what you wanted to hear, but it is something you should consider. You also will not want to hear that I would suggest quitting the shock collar and the electric fence and turning to positive reinforcement methods until you know for sure what is causing the change in behavior. Best case scenario, it has nothing to do with the shock and nothing changes. Worst case, it has everything to do with the shock and you slowly make this situation worse, and you have a dog that's afraid of your neighbor and neighbor's dog and anything else it accidentally becomes afraid of for the next 12+ years.
Whatever you decide to do, you should most definitely consider a physical fence at the very, very least. If he's blown through it once...he's going to do it again no matter how high you set the shock. He's going to see a bunny, another dog, and he'll ignore that momentary pain. It's a sure way for him to run into the wrong not-dog-friendly dog, a car, or run off completely. That would a true tragedy.
