Teach basic obedience to start with. This can be done in the house and your garden until she has had her jabs. Sit, down, come (when called) etc. Get her used to having a collar and lead on and begin to work on the heel command in your garden. Teach some tricks such as shake a paw, give kisses, cuddles, high fives etc. Play sniff and find games with her by hiding a treat under a plastic cup and add another couple of cups with no treat. When she sniffs out the treat she gets it. Use lots and lots of praise, make the treats really yummy ones - sausage/liver/cheese etc (only use tiny pieces though) and don't be stingy with them. Train for 5 mins or so every hour unless she is sleeping, and increase the training tiome as she gets older. Always finish the training session before she gets tired/bored and on a positive note giving her a 'jackpot' of treats ( 6 or so treats at once) at the time. Do not over walk her at this point, on average puppies require about 5 mins lead exercise for every month of age then they need to rest. I would give her 10 mins am, then rest her and give mental stimulation throughout the day (which will really tire her out in itself at this stage), then 10 mins in the evening.)
Hope this helps and remember to have lots of fun with your new furry friend.
