Is my 3lb chihuahua's small size and calm nature normal for her age?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | spayed | 3 years and 2 months old | 3.85 lbs

My chihuahua is not behaving as agressive as a chihuahua should be and she’s very small weighing only 3.85lbs and she’s also fully grown at 3 years old is that a bad thing?

You don't want Tiny to be aggressive, that's not a good trait for a dog to have, so I would consider it good that she isn't! Toy breed dogs are typically fully grown by one year of age, so no it's not a bad thing she is fully grown at three years old. Chihuahuas generally weigh between 2 and 6 pounds, so her weight is normal. i hope this helps!
