We got a golden pup about 4 weeks ago. His name is Tucker and is a gem! He's my son's best friend. Buy the "old mother hubbard" Bitz treats. They are a great way to get her attention and train her to listen to your commands. Most trainers do not want a puppy less than 4 months old. Little ones do not have the attention span. Crating is also very useful. Buy lots of toys for her to chew. If she starts to chew on a shoe, pillow, etc. tell her thank you and offer her a treat instead. When she takes the item out of her mouth, take is away and say thank you. This will train her to bring things to you.
Also, read the labels on dog food. Avoid store bought products. Agway has great stuff. Petco offers a brand, Natures Best. It is made by actor Dick Van Patten who is an avid dog lover. All the products are the best and will keep your dog healthy. Don't buy dog food for "large breeds." They have a so-called grower in them and makes the dog grow faster causing a possibility of hip displascia.
Most of all, give her love and plenty of attention!
