Talking Bird  -  Sometimes you can find a talking bird in the discount shop. If you take it out and press the button, you can speak into the microphone to say a message to your dog(s).

Trainer information  -  The name registered in your Nintendo DS will show appear on the screen as the owner's name, as well as your date of birth. You can change your picture to their choices of avatar pictures. There are eight choices all together.

Getting more dogs  -  Go to bark mode with someone that has a different Nintedogs game type. When you go to bark mode for the first time, you will find that one of you will get a new dog in their kennel. Delete each other from your friend lists, then go to bark mode again. You might get a new dog in the kennel.

Linking  -  When linking copies of Nintendogs to unlock new breeds, keep in mind two things. You can only link with another Nintendo DS system once (and unlock a new breed). The breed unlocked corresponds with your partner's current pet, and it must be a breed that you do not have in order for it to be unlocked.

Obedience training  -  Have the dog do a trick repeatedly until a message appears. Name the trick, then the dog will do the trick every so often. Keep teaching it the trick until it does it for the first time you call it. Note: The dog can only do so much training in one day. For more training, wait for the next day.

Easy competitions  -  When you are almost ready to go into a competition, save the game. Go into any desired competition. Play it, and if the outcome was not as you expected, turn off the Nintendo DS. If the result was what you wanted, keep playing. If turned off the game, you can start it again and can resume just before the competition.

Deleting tricks  - On the camera view of your dogs, tap the question mark under the dog's picture. It will bring up a screen with the dog's information on it, such as name, age, gender, etc. At the bottom is a button to go to the "Trick List". Tap on a trick, and tap "OK" for the dog to forget that trick. If you delete the trick by accident, you can re-teach the dog the same trick, and name it all the same.

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 water your dog after each walk.

Different colored Dogs  -  While at the pound, pick a breed. You will have three choices for the dog's coloring *light, medium, and dark). If you do not see the color you like, tap "Back", then tap on the breed again until the color and/or gender that you want with the dog appears. It may take some time to actually get what you want.

Get your dog to learn lots of tricks  -  Go to "Care" and read the training book. It will show you how to do different tricks. Read one and memorize it. Then, go back and do each step to your dog. Tap on the light bulb in the corner and say the trick. Repeat this until it says the dog has learned a new trick.

Easy owner points  -  Play with a disc, ball, or something. Every time your pup gets it, call it over (or tap the screen a few times.). When he comes, pet it on the head for a few seconds. He should sparkle, giving you one or two owner points. This also makes it easier to get the toy back and repeat.

Back flip  -  Teach your dog to sit and jump. While it is sitting, tell it to jump. Your dog should do a back flip.

Break dance  -  Teach your dog spin and roll over. Make it roll over. While it is on its back, tell it to spin. Your dog should spin around on his back, almost like break dancing.

Dog hang  -  Earn the pull rope. Take out the pull rope. 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

High five  -  When you brush your dog's hair, touch their front paw with your stylus and drag it up. Once you have done that, let go and its paw will shake for about five seconds.

Jump lying on its side  -  Before attempting the jump lying on its side, your dog must know the commands to lay on its side and jump. Tell it to lay on its side and then say jump.

Howl  -  Sometimes at night a neighbor dog will bark, your dog will "howl" back. When he does this, tap on your dog's picture and you will get the light bulb. Teach it howl. You only have to teach him three or four times to learn the trick.

Hop  -  Before attempting the hop, your dog must know the commands to stand and dance. Have your dog do a little jiggy dance. Once your dog is dancing, tell it to jump and it will start hopping.

Lie down  -  While your dog is sitting, stroke its head from top to bottom.

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.

Sneeze  -  When the dog is staring at you, you can touch his nose and it will sneeze. The light bulb will appear . Click on the name and say "sneeze". Do this for awhile and it will learn sneeze. Note: You can do this while sitting, standing ,and laying down.

Walk on two legs  -  First, make your dog stand on its hind legs. Put the stylus on his leg and drag up. He 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.

Refill food and water  -  When you get out some food and water and your dogs consume it, tap the icon on the touchscreen that lets you put the item away. Then, tap it again. You will now have a full bowl of food and water for you dogs.
