She is a mix, but she is a chihuahua/dachshund. She is 6.12 oz and 4 and a half months. What do y'all think?

No bigger than either of her parents.

dogs can keep growing over the course of a year and a half, so your dog may double in size!! i know that sounds weird, but it's true! hope this helps.

tiny dogs are usually done growing by as early as seven months. she won't get all that much bigger.

i dont think it would grow that much bigger but maybe like an inch or so

idk......

Dogs grow till about 2yrs. Then they continue to fill out.

Guess you'll have to wait until she's full grown to know for sure!
