Hunting Dog Training

My fiancee and I just got a Shiba Inu Puppy and we were looking for the best ways to train our puppy to his new environment. Shibas are very agressive and stubborn animals so we want to know what’s the best way to approach his training. I heard alot about doing the dog whisperer method but I’ve read at some places that that method may not be good.

I have two dogs at home and they’re not puppies and they’re not trained. Is it too late for them to get trained from a training place? If I were to get new puppies, should i let them go to dog training school? How can I train them myself? i tried but for some reason it didn’t work, maybe i didn’t do it the right way. I need feedbacks. Thanks

What are some books you would recommend for dog training that you or someone you know found helpful.

I have a dog and I’m not really sure of the breed, but I think she’s a bird dog. She’s a great dog with me, my wife and our 3 kids.
I enjoy playing rough with her. We wrestle on the ground and she will growl very loudly and wrestle back. She will mock bite me, never biting down or anything, but she’ll get my arm or hand in her mouth. She never gets near my face.
I think this rough play freaks my wife out because the dog gets really aggressive, even though it’s still obviously play. She’ll growl and bark, but all I have to do is hold my palms out and say “Brook, Calm” and she’ll calm down. Her tail is wagging the whole time during this rough play and she has never hurt me.
Lately, her growling is getting louder, but I just attribute it to the fact that she’s comfortable with the play, not because she’s getting more aggressive or anything.
Anyway, would a dog trainer say that this is dangerous or foolhardy? I’d hate to be training her by doing this and putting my family at risk.

I want to take my golden retriever max to basic dog training classes to learn obidience and how to walk “nice” on the lead but can’t seem to find any classes in Hull, so if anyone knows of any good ones please let me know x
