Here are some ok hints I learn - Nintendogs: Chihuahua and Friends
Here are some ok hints I learned about:
boxes further away from the house are useuly better if you walk your dog at night you tend to get better gifts, but don't walk them to many times at night or they will end up sleeping during the day.
after you give your dog a bath brush his fur for a while and they get really shiney.
diffrent dogs are better at diffrent tasks: the Chahuahua is good at obediancs but you can only teach them about 3 tricks a day or they where out, the golden retriveers happen to be good a the disk compations take them to the park 2 or 3 times a day and they'll get really good, the boxers are good at agility just take them to the gym a few times a day and they'll get pretty good.
Dont forget to sell items you don't need or your dogs don't like and you will some money for things you actully need.
If you go to a park with a dog icon on it you will get to play with other dogs they will try to get disks befor your dog does so it challeges your dog and they get to play with some one new for a change.
Thats all I got but I hope it's helpfull for you plz give me a good rating I just got my accoutn.
