I got a dog in to train a long time back. GSP. Was about 6 yrs old and had never been out of the kennel. That was a chore till I figured it out. First thing I needed to do was wake up the instinct's! Just didn't seem to understand that in the beginning. Dog had no desire at all for birds! In frustration I took the dog into my quail pen and turned it loose. It just sat there and gave next to notice at all to the birds running around. Took over a half hour and the dog finally stuck it's nose out to sniff at a bird walking by. Did that several time's then tried to mouth one. Bet it was close to an hour and the dog tried hard to catch one. At that point I took it back out in the field on planted birds and coming across one, it actually noticed the bird! All down hill from there. Dog turned into a really good hunting dog for it's owner. Point is if the dog is bred to hunt, you can likely wake it up. But don't expect to take an older dog with no experience out and have it turn on right away, you need sometime's to wake up those instinct's.
