It really depends on how much time you would have. Would you have the time to give them enough excercise during the day? Enough room in the house and so on. You would also need patience lol. If you have the money to care for two, like if they had to go to the vet or got hurt or something. If you have that, you should be ok. Another thing about having two is they would play with each other. I'm sure some other people with two dogs will give more advice, but heres an online guide about finding a good breeder, its really helpful. Have you considered rescueing? Its hard to find puppies at most rescues, but you could check into it. They might have some reccomendations as far as a breeder would go.
