Here's why your question is a bit tricky:
* In Utero: This refers to the time a puppy is developing inside its mother's womb.
* 1 Month Old: This refers to a puppy's age after it has been born.
If you're asking about the size of a Rottweiler puppy at 1 month after birth, the answer is quite variable. It depends on factors like genetics, litter size, and nutrition.
However, a general guideline is that a 1-month-old Rottweiler puppy will typically weigh between 5 and 10 pounds.
It's important to remember that Rottweilers are large breed dogs, and their puppies grow quickly. If you are considering getting a Rottweiler, it's essential to research the breed and understand their needs for proper socialization and training.
