His age would not be an unfixable problem if you had not let him catch a live bird. Now the dog knows he can catch the bird.
Thats why I use the trick with the hose on the bird. The dog figures out he can't get the live bird.
If you are willing to dedicate 15-30 minutes a day everyday you maybe can train this one. But I would find another dog myself.
A pinch collar is similar to a choke chain. It is made of leather and slips like a choke chain. It has nails on the inside facing the dogs neck. The first thing you do is file the nails smooth before pup ever wears it. The spikes will grab pups skin as it tightens and pinch rather than choke the dog and possibly hurt his airway like a choke chain.
