How much should a healthy Chihuahua weigh?

Healthy adult Chihuahuas typically weigh 1.5–3 kg (3.3–6.6 lb). Because this is such a narrow range, even small amounts of excess weight matter — use body condition score alongside scale weight for a complete picture.

How can I tell if my Chihuahua is overweight?

Feel the ribcage with light pressure — ribs should be easily felt without pressing. View the dog from above — a healthy Chihuahua has a clear waist. If the dog is barrel-shaped from above or ribs require firm pressure to find, it is likely overweight.

Can being slightly overweight really harm a Chihuahua?

Yes. Even 200–300 grams of excess weight represents a meaningful percentage of a Chihuahua's body mass and adds real stress to the knees (worsening patellar luxation risk) and heart. Do not dismiss mild overweight as insignificant in a breed this small.

What body condition score should a Chihuahua have?

4–5 out of 9 on the WSAVA BCS scale represents ideal condition. At this score ribs are easily felt with light pressure, a waist is visible from above, and there is a mild abdominal tuck from the side.
