But this is what makes training fun, figuring out what it takes to get the most talent out of each dog.
I'll be honest, I like doing the SAME THINGS each time, each dog, etc... and having the same results. It's predictable, easy, and you get to be smug when everything is well.
Not field training any dogs - I want to try with my middle dog, but he is very very high prey drive in a "I want to eat it instead of bringing it back" way - and yes, this happened while field training with a live bird. I'm putting obedience first and seeing how he is in another year before trying field again. I don't want to be stuck chasing my dog around trying to get a bird from him before he eats it alive! Obedience training will fix that.
He's different from his dad who was the absolute opposite (very obedient and willing to do anything for me, but hated the taste of birds and you could see his disgusted look each time he had to pick one up).
And I suspect my baby who is a full sibling of the middle dog will also be different. I'm not sure at this time. He's not food driven the same way the middle dog is, but seems very willing to put anything in his mouth. I am hoping he is somewhere in the middle (wants to get all the birds, but thinks of them as "toys" vs "food").
Dad dog - has a workhorse mentality + agile and delicate. Needs a soft hand and positive energy from me or he folds.
Why did I want pups from him? He's got athleticism and smarts that most show goldens seem to lack, I think. He's catlike. He can jump anything without making a noise.
Pup # 1 (middle dog) - I don't honestly know if he's as smart as his dad. He's more flamboyant, hyper, flashy, and very much an overachiever. Some things, he needs to be taught them a little different than I taught his dad. He's not a "do it right one time, learn forever" type of dog like his dad is. That's where I had to change up how I teach some things. For example, he's learned the "go out" for obedience (which is go a straight line out until I stop him). But he has me pulling my hair out teaching him a legit "mark" for the go-out and also gloves. It's just not computing the way I taught his dad. So changing that game. He's also a bottomless pit of energy. He wants to play nonstop. I could train him for 2 hours and he'll be kicking and screaming about being put on the side while I train another dog.
Pup # 2 (baby) - I'm finding he has a lot of desire to please, eagerness to work, but part of the complication in training him is the jealousy from the other dogs... other part is he's also very distracted by everything. I think part of that is he's more independent than most dogs I've had. That doesn't bother me right now, because a lot of golden boys start off being independent and goofy, but by the time they are 5 months old they start becoming very attached to their people and listening better.
^^^^ All this is my scattered thoughts on bringing home my equivalent of littermates (full brothers born 1 year apart). I'm remembering why I'd always said I wouldn't buy a puppy before the other dogs were at least 3. o_O! So much easier focusing on training only 1 dog.
When people talk about getting littermates, I do think that they are possibly stretching themselves thin - or stretching the time they can commit to each pup pretty thin.
