More dogs
After thirty days with your dog you can get two more dogs and train them like your others.

Making friends and parties
When your aloud to take walks with your dog, look for other people and stand next to them, then they will talk to you about their dog sort of liking yours(as a friend), then do that a few times and the owner will say the two dogs are friends. Then when you get a few friends, on sundays your mom will ask if you want to have a party, say yes and the next day your friends will come over, although, your whole day will be skipped.
