Rat Terrier sizes?

[fuzzy_ferret_luver]

My senior dog, Sugar, was from the Humane Society, and was called a rat terrier. However, my best friend has a rat terrier, and she's about as big as a toy fox terrier. Are there different sizes of rat terriers? Sugar weighs about 22 pounds, and my best friend's is much smaller. He says it's because of their different life styles, his is very active and our dog is a bit more lazy, she can be playful but she's not one to go outside and chase a frisbee or a ball, but she is older. So, I guess what my question boils down to, is, is my RT a standard and my best friend's a mini RT? Or do you think Sugar is a RT mix? I don't know what her mix would be though, she doesn't really look like any other dog...

Rat Terrier sizes:

Miniature: 7-13 inches and 5-13 lbs; Standard: 13-18 inches and 13-36 lbs

There are two different Rat Terrier body types. Different organizations refer to them in different ways.

The first and most common is the type "A", which has a square shaped body when viewed from the side. The distance from the top of the shoulders to the ground, and from the tail to the shoulders should be about the same. This body type is considered by UKCI a classic "type A" Rat Terrier, and a "Rat Terrier" by UKC.

~~~~~~~~~~~~~~
The second type is the type "B", and is not as common as the type "A". This type appears longer in body than tall when viewed from the side, with the perfect height to legth ratio being 7to10.
This body type is considered a type "B" Rat Terrier by UKCI, and a "Teddy Roosevelt Rat Terrier" by UKC.

Rat Terrier Sizes

Rat Terriers come in three basic sizes with few exceptions.
"Standard" between 18 and 25lbs.
"Miniture" between 10 and 18lbs.
"Toy" 10lbs. and under.
Some Rat Terrier associations have
"Giant" which is 25lbs and up, and "Tiny Toys" or "Tiny Tots" which are 4lbs. and under.

I like the Teddy Roosevelt type. The last quote is from a breeder's website, but upon further investigation, it is a BYB...so, I'm hoping it is accurate, but I could be wrong. The dogs pictured are some of the breeder's dogs.
