I'm going to adopt a maltese puppy that I dream about for so long. I found a breeder in my region that has a puppy . I watched him grow when he was just 1 week old! The parents of the puppy are both about 4 pounds. But I find that the puppy is growing too fast. Breeder said that it will be 4.5 pounds adult. But now he's 2 pounds already at age of 7 weeks! What do you think it will be full grown? I'm affraid the puppy will grow too big and may reach 6-7 pounds! For me its small size is very important so I can easily travel with my dog and take it in my bag everywhere I go. I live in a small appartement and want to paper train my puppy so he will not need to go outside when it's -40C! Otherwise the puppy seems to be sweet and healthy and I'm happy about it! Please give me some comments about how much the puppy could weight when it reaches adulthood? Thank you!
