I got a whole pack of 'em that I found yesterday - they're not mine, I just found them.
Eat the lightbulb!
When your dog is learning a command, ex:lay down,roll over. A lightbulb icon appears in the top right corner of the screen. Click on the light bulb and record your command. If the dog accepts the command, a sketchy like lightbulb appears over their adorable little head. Grab the lightbulb with your stylus then drag it to the dogs mouth. And they will EAT THE LIGHTBULB like a treat! This also works with bone icons too.
Easy way to find hidden presents
When going on a walk, watch the top screen. When the dog icon stops moving, there is a hidden present coming up shortly. Be cautious, however, as this is also true when garbage is coming up, or your pup simply stops by itself.
Get unlockable breeds easier.
Do Bark Mode with a dog in a breed that you don't have.
Example: Do Bark Mode with a Shih Tzu and after you do Bark Mode with that dog, you will be able to buy the Shih Tzu breed at the kennel.
NOTE: This only works the first time with each different version of the game. So you can do this trick one time with Labrador & Friends, Dachshund & Friends, and any other version of Nintendogs.

You can walk your dog once every 25 minutes. Wait 25 minutes with the game on, in sleep mode, or off before walking your dog. Also, it will not be very active during the day if it stays awake at night.
# General Walking Tip
While walking your dog and he or she seems edgy, give the leash a little tug towards the way it is walking. The dog will start running. Also, if you want you can give it a tug while running upwards and it will do a jump.
# Walking Your Dog More Than Once a Day
You can walk your dog once every 25 minutes. Wait 25 minutes with the game on, in sleep mode, or off before walking your dog. Also, it will not be very active during the day if it stays awake at night.
# Longer Walks
Mark out the path on your map, ending it at the house. If your last few steps ends at the house, wait 25 minutes, then your dog can go slighter further on the next walk. Note: Make sure to give your dog water after each walk.
# Question Marks on the Map
While marking out where you want to go on the map, try to get as many question marks as you can along the way. There are either other dogs or gifts that your dog will find with each question mark.
# Blue Circles on the Map
While walking your dog, the blue circles that appear represent places to go to the bathroom.
# Stand Up
Once your dog has learned to beg, lift its paw up, and make it stand on its hind legs. It will stand and you will be able to teach it how so it is remembered.
# Hand Stand
Teach your dog to lay down and beg. While lying down, tell it to beg and your dog should do a handstand.
# Walk on Two Legs
First, make your dog stand on its hind legs. Put the stylus on his or her leg and drag up. He or she should now be standing. Note: Teach your dog that trick so it is remembered. Then, pull its paw to the area that the training icon is located. It should now be walking on its hind legs.
# Wave Paw
Get your dog to sit and hold an ear back. The dog will wave its paw. Do it three or four times to get the trick.
# Break Dance
Teach your dog to spin and roll over. Make it roll over, then while it is on its back, tell it to spin. Your dog should spin around on his or her back, almost like it is break dancing.
# Rag Doll Puppy
When your dog is playing with the pull rope, grab the other end and pull up with the stylus. This should make the puppy hang on the other end like a rag doll. Drag the rope around the screen and eventually the dog will fly off.
# Throw Your Dog
When you have the Pull Rope, try to get your dog suspended in the air. When it does, make it turn slowly (or it will fly off), and release the stylus. Your dog should fly away.
# Dog Hang
Get the pull rope, then take it out. Wait for your dog to bite it. If you quickly slide the rope up while it is biting, one of two things will happen. It will either let go, or the camera will go above the dog, and it is hanging on the rope. To stop, let go of the rope or swing the rope around until the dog loses its grip and goes flying.
