* Chihuahuas are the smallest dog breed, typically weighing between 4-6 pounds.
* Boxers are a medium-sized breed, weighing between 50-70 pounds.
There's a huge size difference between the two breeds. It's like comparing a tiny mouse to a large dog!
Perhaps you're thinking of a different breed? Or maybe you're imagining a chihuahua growing bigger than it should. If you're concerned about your chihuahua's growth, it's always best to consult with a veterinarian.
