Hey all! I have a Chihuahua puppy named Bella-rose and she is 17 weeks old and about 2 1/2 pounds. I've never owned a Chi before and don't know how they grow. Her breeder said she is supposed to be 5.5 lbs fully grown, but she guessed that according to her 9 week old weight. Since 9 weeks she hasn't grown much at all and our vet said she will most likely get to be 4 pounds and stop if she's fortunate. Also, she's VERY sqaure and compact so she looks even smaller then she is. For fellow YTers with Chi's how much do you think she will weigh fully grown? Thanks in advance
