Some people say you should teach your dog to signal in a certain way when it has located the hide. Others say you should learn your dog's signalling body language, whatever that happens to be.
I don't think I've commented in this thread until now...
I can speak a bit on this. My dogs point, though the current dog is a lazy pointer. He'll stand there pointing at it with his nose, tail doing nothing - or wagging. if the scent is on the ground and the object is not there, he'll indicate this by following the scent, actively sniffing in a pattern of his own design. I can encourage him to be a bit more efficient but I don't.
I'm a golden retriever man. I've pretty much always owned a golden, as much as I could. I've had dogs from the same lineage for a while now. They're a robust specimen with a nice reddish hue to their adult fur.
My dog is meant to hunt and retrieve. It is also meant to track. The hunting and retrieving are quickly learned but a young golden is hard to keep concentrating for long. The play method and lots of practice helps. They settle down to become acceptable trackers. They're not ideal but they're better than many other dogs and they're certainly better than a human nose.
Also, regarding the hunting, the current one is a very lazy pointer. At least he stares at it, though he's easily fooled by the sneaky partridge (as am I). He'll happily bring back what I shoot as he knows that I appreciate that and they want to make you appreciate them. That's half the battle, right there - at least with goldens. They're eager to please. You just need to let them know what pleases you.
It also can help to have a 'special toy'. They only get to play with that toy when they're working. So, when they see you head out with that toy, they know they're going to get to please you and play with their special toy. You do need to limit how much they play with that special toy to make sure that it stays special. You can even just use a new tennis ball. It's a special day when they get to play with a tennis ball that they've not chewed on before.
This one is short-named Zack. I call him Stupid. He's a loveable dog, but he is sure stupid - at least as far as godens go.
See, he'll keep bringing a ball/toy back to you over and over again. You can throw two in completely different directions and he'll be smart enough to bring them both back.
This is because he can fit two tennis balls in his mouth.
So, when you're done playing with him or done giving him a workout, you just throw three balls.
He can't fit three balls in his mouth. He will be all sorts of frustrated but he will keep trying to fit all three balls in his mouth until you call his name and tell him to come (or whistle properly).
If you really want to play with him, and give him some neck strength, you can use a long/heavy stick. He'll happily bring that back. He'll try to bring back basically anything you tell him to bring back.
When you're done throwing the stick, throw it up high so that it goes deeper into the woods. He'll pick he stick up in the middle and be unable to fit it between the trees. Eventually, he figures out that he can drag it by one end but he'll try to carry it in the middle for quite a while.
He also appears to get a bit mad at you if you do that to him. That's okay. If he's not happy then you can always throw the stick again. He will eventually decide to not go get it but you've really got to work at it to make him do that. As far as the balls go, he'll retrieve those for longer than I can throw them. It's just the sticks in the woods that frustrate him.
I've been watching the thread and enjoying the progress. I'm not into showing my dog. He's got enough of an ego already and I prefer a dog that works for me. So, seeing this progress has been a bit novel. I'm not even really familiar with this breed you have.
