Our house is pretty crazy we have 3 britts and a golden retriever.
Pee-J, our 10 yr old male is gunshy and I've never hunted over him. Not sure how it happened but it did. Oh well, he's still a great family dog.
Then we got Piper, she's two and a half now and has a very unique personality - she's definitely my wife's dog.
Then this past Easter we rescued a 5 yr old female, Maddie. Her owners split up and the husband didn't take his hunting dog and the wife couldn't handle her high energy. So, we took her and she's become my dog. She'd never been hunted over but showed a lot of birdiness.
Anyway, I don't have a lot of time to train them and I don't have the cash to send them off to pro. We were worried about Piper because she didn't seem very birdy. So, we joined the local pointer club, got some good tips and did a bit of bird work with pigeons. Not a lot really. Mostly we take them out looking for birds. After we got the first grouse they really seemed to clue in and now they have a good idea of why we're out in the woods.
Here is Maddie pointing a grouse in the trees. She held point for a solid minute before we caught up to her, and by then she was so excited she was vibrating!!

After she flushed the bird it flew straight at us. My buddy never got a shot off but I got a great pic of her watching it get away.
If you want to win field trials with them you'll need to do a lot more training than we did, but if you want to hunt with them then go hunt with them. Each time you go out you'll see something you can work on or improve.
