It's such a pity the way some people treat their animals Wolf, you have a beautiful dog who was born to run but can't be trusted. Perhaps after a while he might calm downYep. Sadly he was abandoned as a puppy and fended for himself so his already high prey drive is a realised & imprinted behaviour. Can't let him off the lead in all but the most secure areas as the chase over rules all obedience. Can't blame him though as its in his breed to start with which wouldn't bother me per se and would provide me with plenty of rabbit. But he would go after livestock, deer etc... Which is a little more awkward. And as said before he's to unpredictable to guarantee bringing the quarry back to me to dispatch unmolested and my own moral stance on these things is that even for a rabbit the death should be clean and suffering minimal... So sadly I can't work him though I would love to.
