5 weeks is very young to be away from it's mother and siblings - important skills in dog language and socializing occur from 4 - 8 weeks of age. Some breeders are now keeping the pups with their mom and litter until 12 weeks to ensure proper behaviours are learned.

For 5 weeks of age, don't worry too much about training/socialization until the pup has its second set of shots. Work on house-training, crate-training, teaching pup its name but I wouldn't worry about too much else at this point. The attention span is pretty much non-existent and you don't want to bring your pup or expose him/her to other dogs until shots are up to date in case of disease.

Make sure toys are appropriate for size of dog/puppy teething. I'd recommend you get a puppy kong (check the sizing guideline on the back of the product). This is a great toy for keeping dogs out of trouble and is especially good stuffed with banana/peanut butter and frozen for a few days - it will really help when puppy is teething later.

Make sure pup is on a good dog food - Acana, Orijen, Fromms, Blue Buffalo, Eagle Pack, etc are good dog foods and aren't available at the walmart or grocery store. Ol'Roy, Alpo, Iams, etc is the equivalent of a human eating mcdonalds every meal every day. Pup should be on 3 smaller meals a day - when pup is 6 - 8 months you can make the jump from puppy food to adult food and cut meals down to twice a day.

Don't worry about exercise too much at this point, either. Yes, puppy will need to be entertained and played with but forced exercise should be at a minimum for the sake of the joints/muscles. Especially with how young the dog is - I wouldn't do much more than a walk around the block (probably with a well-fitting harness rather than a collar) in a dog-free area. Unlimited play time for sure to tire out the puppy but too much forced exercise won't be good for him/her.

Also, try not to pick up the dog too much - most small dogs have issues because the owner treats them less like a dog and more like a child. So many times you see a person with a small dog on the ground, then a big dog comes over and owner freaks and swoops up little dog. Little dog then thinks he's better than big dog (being held over the head and higher up than big dog) and never learns to properly socialize with other dogs.

That's all the advice I have for a little puppy. Different advice for when they get older. Look into puppy classes - ask your vet for recommendations or if you see a well-behaved dog walking down the street, ask the owner where they took their dog. Cesar Milan is great, but most people benefit from hands-on training instead of what they see on tv.
