Awww - you'll need to post a photo (I go all broody with puppies

)
Retreviers are incredibly smart (though some do have the loopy gene

)
The main thing to remember with any puppy is make it do what you want when it's little, because if you don't it'll turn into an unruly adult. A vet told me this when I took my first GSD for it's vaccines and I've never forgotten it !
Some basic sit training and getting them used to walking on a lead without pulling etc maybe only 5-10 minutes at a time to start with, puppy socialisation and training classes are a good thing, but you can do the same yourself. We had retrievers when I was younger, they're very smart and quick to learn. We had a 'loopy' one, rehomed to us by it's owner after it chewed though (amongst other things) a live freezer cable ! He was always nuts - but responded really well to gundog training. They're a bit like kids - the more you put into them, the more you get out

Annie will be along soon with proper training advice - she's more of an expert than me

But good luck with them (and nice to see you back)
