J78--- I think it all depends on what you are looking
If you just want to take him out with yourself not take it too seriously then its never too late
especially if they are OK with gun fire--- if they are skiddish with that you might be in trouble
But really all you need its a dog that will sit----- and take the hand signal to where you want it to go--- if its a small pond and they see the duck down-- your good to go
Not going to win any field trials--- but fun to spend some time with your dog doing what they love
Its tough though when you don't have a lot of ducks flying and you expect the dog to sit for 2 to 3 hours
Take my experience with a grain of salt. Ditto on the above.
I guess a few questions for me would help:
1.Does the dog have any gas or a strong prey drive? (will it chase ANY rapidly retreating object) and no I dont mean does it have a flatulence problem, they all do *grinnin*
2. Is the dog oral? Does it like to bring you things? My intact male will not greet me at the door without something in his mouth even if its something of my little girls which he knows he's not suppose to have. *shruggin*
3. Do you feel like the dog is tractable (still easy to train new things)
4. Meat retrieving takes an athlete to do it all morning. Are there any hip or elbow issues since the dog is middle age?
5. For me, early on especially hunting, I could either TRAIN MY DOG during a hunt, OR HUNT, not both. If the dog is loose and your early on in your training its not fair to the dog or other hunters with you if your constantly harassing the dog to behave and follow commands it is not fluent in. On a leash or a long line for sure. If your new to training and aren't confident in your skills I would not use an E collar in a hunting situation as one can, (no reflection on you here at all) on occasion, punish with the collar rather than enforce known commands. Your emotions are high at the duck blind, and if the dog has any gas at all, it is JAZZED to the max with shot flyers in its face. Both can make for a tough morning with a loose dog, mature dog OR a pup.
So, the first season for me, I had a good group of guys I hunted with and I have shot my share of ducks so, I kept my gun in the case and worked my dog. One thing I wanted to do was train a gun dog with a clicker using Operant Conditioning. Being new at it and with a totally different mind set, there was no way I could hunt and train at the same time. But thats just me.
