I have a 12 week old male chihuahua who weighs 4 pounds. At 9 weeks, he weighed 3 pounds and 1 ounce. He’ll probably be bigger than the AKC standard, but how big do you think he’ll be as an adult?
it depends on the type of chihuahua you have. most usually don’t weigh anymore than 5 pounds but if yours is already 4 pounds at 12 weeks it’s going to get bigger than that. i have a 5 pound chihuahua that weighed 1 pound at 9 weeks so yours might be around 7-10 pounds fully grown.
