Reni Is A Toy. Trixie is a Miniature. Pumpkin is a Decker Giant, or Standard. It kinda works the same as Poodles. There are some rumors of Tea cup Rat Terriers,but I would think they might be Chi/rattie mixes.

domino is a standard type B if i remmber right

Dink is a Type A (Toy) Rat Terrier...I was told by the breeder that both his parents are full Ratties (we didn't get papers) but I had also heard that they bred Rat's with Chi's to make the Toy  'back in the day'  I dunno???  When we got Dink I didn't know he'd be a Toy...I just assumed he would grow to be 12-15 lbs.  I heard that was the size range that all Ratties are supposed to be.  I didn't know till I joined here that they come in different sizes.  I'm assuming Dink is going to stay a Toy b/c he's a year old now and under 10 lbs.  This is Dink at 3 mos he was only as high as 2 bricks as you can see (not counting his head)

here's a "family tree" i found on the internet for the rat terrier

Thank you!!  He's a keeper!!

I just had to go back to my calendar and look, he was born in June, we got him in Sept, his first vet appt was Oct 1st and they said he weighed 6 lbs, he was 15 wks old.  He was and is very long legged.  He's 1 now and only weighs 8 or 9 lbs (he's due for shots so I'll have the vet weigh him again)  He's very sleek and muscular.  

This is one of the most recent pictures of him.........  

Dink looks about the same size as Morgandy, just a hair smaller.  She weighs 9 pounds now but needs another 1 or 2 pounds so that makes her a very small mni-rat!
