Dog Trainer For 3 Month Old Puppy.

I'm looking for puppy obedience training for my 3-month-old dog. Since he's still too young to go outside, the training will need to be done indoors til he gets his last set of shots. We do have a backyard where some training could take place, but I'd prefer the sessions to be primarily indoors as that's where he primarily is. I'm looking for a trainer that focuses on basic commands, socialization with my cats, and positive reinforcement techniques to help set a strong foundation for good behavior. My dog Bentley, is a 3-month-old golden retriever who will be turning four months on February 27. Very energetic and friendly. No special care needs.
