This is a friend of mine's dog...He is a rat with papers, but she sent me this picture asking if he is type B or Type A.  I thought Type A, but he is much shorter than her other rat.

 Looks like he's inbetween....maybe part A and part B?  Breeders aren't supposed to mix them but they could....

Here's a pic of Mayfly, type B, with 2 type B parents.

He looks to me like he has B front legs and A back legs...maybe he is a mix of both.  He's a cutie no matter what, but they are breeding their dogs and I know that the female is a type A.

Yeah, his back legs look too long for a B.  He could have 2 type A parents and one of them has a "B" in their family somewhere.

To me, the photo looks like he is a little pudgy and hiding his true diminsions.

oh B for sure! even if the angle of the couch make 'um look un-even. its something about the proportions of his legs that makes him a B his Coffin(forarm) bones would be much longer,Look at Caesar and Shamus (Shamus is a short A )Caesar is a true B see the difference? I lke B's just as well as A's since I got BOTH! Lucky you what a sweety!!!! cute little athletic body!

The more I look a the pic the more I think pudgy A or half and half.  Check this link out: http://www.nrta.com/newratstandards5.html  To me he looks like the "tuxedo" rattie below only he's chubbier.  The Class B rat on the right looks more like my Mayfly who I know is a B.

"The Rat Terrier not only comes in 3 sizes but also two body types. Rats that have a square, long leg look are shown as Class A.  Rat Terriers that have a shorter leg length  in proportion to body are shown as Class B. The following standards will apply to both classes with the exception of the difference in body to leg length (shown below) also see (Body Standards). These are two separate and unique body styles for the Rat Terrier and to keep them this way, it is recommended that they never be bred together. They have been with the Rat since their American existence, and there are no differences other than body style. Both Class A and B dogs share all of the same wonderful rat terrier traits. To deny either style would be to taint the existence of the breed. "
 

CLASS A 10:10:9 RATIO

CLASS B 10:8:7 RATIO

thanks Im glad you posted that I keep that too! it the best example Ive seen ou there! I guess after you see as many as us it pretty easy to tell the difference...and as for the breeding a's to b's unfortanatly a LOT of people don't go by that,in the quest for really small A's!  cash's dad (see insert)is and Very Hefty B MINI! his mom a true toy A (2nd pix)and luckly Cash is a tiny TYPEY A that looks just like his dad in color but his mom in size...this breeder uses him on ALL of his DAMS and get typey toys! Now Shamus..his dad(3pix) looks JUST like Cash(no relation)His mom is a STOUT A and he IS! STOUT! looks like a short A(or TALL a) but he is still young at 10mons he is slimming down a little and looks more like a dog instead of a pudgy pup,he might even grow a little more...but he defiantly!! isn't a B! I never thought Polo would be taller than Cash but he is now !so sometimes they surprise you!

well had to go out and nap some pix! didn't realize that they had grown!!!look at these HAPPY smiling faces!!! we (sept caesar)will be 1 yr soon...Cash is the oldest his is 6-24!!! wow!!! then Shamus,7-7,then Polo! oh they grow soooo quick and my gradn -rat-pup Domino too!oh if they could stay pups....

Brielle is a type A, and so is Winchester, but she is shorter than him.

YEA GIRLS DO TEND TO BE A LITTLE SHORTER...depends who they took after mom OR DAD...SHAMUS(LEFT)( CASH ON THE RT) 7 MONS IS FINALLY GETTING A LITTLE LONGER LEG...BUT HE IS STILL STUBBY!hIS LEGS ARE THE RIGHT LENGTH HIS bARREL IS JUST SO BIG HE LOOKS SHORTER...

He looks like a B to me

I think that little cutie doesn't have a long enough body to be a type B. His front legs look on the shorter/ stockier side, but his back legs seem to raise up to an A standard. It may be the angle, but his body appears shorter. CoCo is a B, and a pretty long/tanklike one at that, and Mayfly has the same build of what the NRTA describes as correct conformation for a B. I think this boy is built more similar to my Gus, who has shorter front legs, and longer back legs. When you stand him side by side with CoCo, not only is he taller, but shorter in body as well. Plus, he isn't the sturdy build that she is. My guess (since he was a rescue and I have no way of knowing) is that Gus is a cross between an A/B and that's why he like this other little guy, doesn't quite fit either dimensions perfectly.

This is CoCo ( the best side view I have) versus the stature of Gus.

Also, Donna in your pic, you can see just by Remi's (the one on her lap) front paws and body type how much shorter the B's are in proportion to the A's. I knw Brielle and Winchester are larger then he is too, but he looks long even in that picture. And I know that he is a true B as does Donna because he and CoCo are out of the same litter.  Your pic is a good comparison, even though Remi isn't standing up.

Amy (an old member) her dog as between an A and a B.

Well, I went to see him in person and I think he is a Type A.  He is very muscular(looks fat in the pic, but looks quite solid in real life)  He is a little shorter than Tinkerbelle, but I think he is a small standard Type A.  He was very sweet and Tinkerbelle was a little smitten with his studliness!  Their female is much bigger than Tinkerbelle, so I think that is why he looks so short in the pics.  She is more the size of 15-18lbs and taller than Tink....kind of like Katie Scarlett with those super long legs!

Tinkerbelle is 13lbs and a petite standard type A.

a really good example is to measure from their elbow to the wrist,on true (B's)TEDDYS IT's very SHORT! SEE CAESAR LITTLE STUBBY ARMS THEN LOOK AT CASH,he is a true A but tiny! And there little forarms are VERY muscled too.A's tend to be very fine boned..The long back doesn't matter ALL my boys have long backs!

oh..she is just the cutist little A girl! look at those long shapely GAMS!even if she is tiny she is STILL a A
