2 year old MUFFET is 6 to 6 1/2 inches tall from floor to  top of her back. Bug is 3.0 lbs
elbow is 3  inches, If you go to shoulder you have 5 inches.
Elbow 3 inches,  shoulder  5 inches.
The proper way to measure height is by the dog's shoulder which we can see here is 5 inches. So this dog would be listed at  5 inches tall. I though prefer to measure from the floor to the top of back.                      She would then be 6 1 /2 inches tall from the floor to the top of her back.
I MEASURE HEIGHT TWO WAYS : FROM FLOOR  TO THE SHOULDER AND ALSO TO THE TOP OF BACK
To Elbow 3 inches
To  Shoulder 5 inches
To tallest part of back 6 1/2 inches.

FACT
It is the myth that exact adult weight can be predicted from the weight of a young puppy. Only Scammers and dishonest breeders will promise an exact  adult weight. Responsible breeders  will admit that an educated guess can be given based on sizes of paretns, relatives, puppies from past litters and puppies current age, weight and body size , along with bone structure.

PUPPY WEIGHT-

FACT: Weight doesn't predict length or height of a Chihuahua.
FACT: A SKINNY adult Chihuahua can be large. If you want a low adult weight  and think low weight means "tiny" then  would you be happy with a  THIN 2 1/2 lb 13 inch long large Chihuahua?



MOTHERS MILK-
FAT PUPPIES- Some mothers have such rich milk that their puppies end up little butter balls and large for age. These young pups chart 5 lbs for baby fat alone at 8 weeks and at 12 months chart 3 lbs

THIN PUPPIES- Some mothers have poor milk quality no matter what you feed them.  So you take a thin puppy and switch them over to a mother with fattening milk and the skinny low weight puppy gains alot of weight. So much for accurate charting of puppies in the early weeks!!


PLACENTAS-

Some fetuses have small insufficient placentas and do not grow well  while in uteri so they are born extra small and even weakly.These ones can catch up by 8 weeks

Some fetuses have large over sized placentas . Such puppies are huge at birth causing mom to need a c-section. The growth of these puppies slows rapidly after whelp.
