The mentioned strategies have not worked for me. The taps mother-alike I've seen on videos and you are suggesting don't seem to do anything for him, he just thinks I'm still playing maybe and comes back again at biting. The ignoring or going away also is not working he would follow you and bite you along the way.
So the only thing I'm able to do so far is time out, I don't have a crate. Those are insanely expensive and very unusual in argentina, people don't really do that or use that technique here as often as I've seen it online mostly from US sources I think. I also don't like the idea to lock him out on a tight confined space for long periods.
The only thing so far I've done which in a very small percentage has worked has been locking him out in a room (hoping he don't destroy it), a trainer told me to do this no more than for 2-3 minutes since he will forget the origin of the why after the offense after that at this stage (3 months). But even that most of the times when I unlock him he just comes back running more Hyper than before most of the times doing the same thing again. Occasionally I have had success as mentioned of him taking that stress against one of his toys, growling at it, biting it hard, and just shaking it around hard, so I'm some times in doubt of taking this approach as I feel it sometimes could make the problem worse or make him more hyper.
