When is a Chihuahua fully grown?

Most Chihuahuas reach adult weight by 9–10 months, with some continuing to fill out slightly through 12 months. Toy breeds mature faster than medium and large breeds.

How much should a Chihuahua puppy weigh at 8 weeks?

A puppy expected to reach an adult weight of around 2–2.5 kg typically weighs approximately 400–700 grams at 8 weeks. Exact weight depends heavily on parent size and individual genetics.

How often should I feed a Chihuahua puppy?

Four meals daily from 8–12 weeks, three meals daily from 12 weeks to 6 months, then two to three meals daily from 6–12 months. Frequent small meals help prevent hypoglycemia in this tiny breed.

What should I do if my Chihuahua puppy stops eating?

Contact your veterinarian promptly. A Chihuahua puppy that is not eating is at real risk of hypoglycemia — this is a veterinary concern, not a behavioral one to wait out at home.
