Curious, its been so long since I have had a dog. How old before they reach full size. Zoe is 5 months now I think she is around 14 lbs maybe a little more. At least I haven't had anyone ask me if she is a chihuahua lately.
Typically between 6 and 9 months… height is usually when their growth plates close (in the ankle of the front legs)... and that is usually someplace between 6 and 8 months they have their full height... they do mature body for up to 2 yrs.... but usually their height is done early on.
Sounds to me like she will be to the small size...
I just had Liyah at the vet for her rabies shot. She is 5 months old on Tuesday and she weighed 14lbs.
For reference, visually, Liyah looks to be only a couple inches shorter than my girl Ruby who is 16.5 inches - I haven't measured Liyah's height. Ruby who is 4yo weighed 18.2 lbs today…lighter than usual. Ruby is really lean and usually weighs around 19 - 19.5 lbs. Liyah, has her running so I'm sure that is why her weight is lower!
My Noel is 5.5 months and she weighs 20.5. She is tall and very thin. To the point where her ribs show when she walks, although she eats plenty. does this sound normal?
Some are just built that way… tall and narrow framed.. and sometimes it can take up to years for them to fill in... or she just might stay pretty much tall and narrow ..... if she is eating well, I would not worry about it...
