If you are expecting your dog to compete or hunt you should take them out around these environments just like anything else. I usually start with myself and my car since these are my puppies first interactions with me.
I start in a quiet room when I pick them up and have treats on hand,I patiently let the puppy check me out or just roam around a little while I wait. After they are comfortable with my presence I will make sure the puppy follows me well and head outside. I let them go potty and take them to the car. If she is not interested in it I open the door and shut it a few times so the sound isn't so startling. I put him inside and let him roam around before placing him in the crate.If I have a long way to go I stop frequently to check on the puppy and let them out a little.
The first car ride is a good example for you to see how an everyday occurrence needs to be broken down. This will be the same for your yard, house, other dogs, and,cats. If the puppy seems frightened and you don't see a reason for it (ie pulling on a leash and crying loudly when they first see an automatic door) just wait for a minute and take off the slack. Don't pick them up or try to reassure them it will only hurt their growth.
When introducing a puppy to a new dog you must have control of the situation and trust in the other dog. If the other dog shows aggression just pull your puppy away quietly, no fuss. Generally puppies can handle their own with puppies their size but be sure to break up any spat without coddling. I'm going to leave off here because I could write a chapter on this but if you have any questions don't hesitate to write me an e-mail or call.
