Here's a more specific breakdown:
* At birth: 4-6 ounces, about the size of a tea cup or a small loaf of bread
* At 8 weeks: Around 2 pounds, about the size of a small kitten or a loaf of bread
* Fully grown: Between 4-7 pounds, about the size of a small shoebox or a small kitten
It's important to remember that these are just general estimates. Individual Maltese can vary in size, depending on their genetics and diet.
