There is no guaranteed way to determine the actual adult weight of any Chihuahua. Genetics are a tricky thing. Even if your puppy’s parents are tiny, a great-great-great grandparent may have been three pounds heavier. Genes can be passed down from as far back as seven generations.
We use this chart as a guide to determine the estimated adult weight of our chihuahua puppies. We also track dog’s pedigrees to help us reach a much better estimate for our puppies’ adult weights but there are additional factors beyond genetics that come into play when making calculations: The activity level of the dog and if the dog receives proper nutrition.
The Chihuahua Weight Chart is a tool that can be used to help with the estimating of weight that a Chi puppy will reach once full grown. Again, this chart is no guarantee but it helps hone in on a more accurate estimate – Usually within 1/2 pound.
