Mini Border Collies? Is there such a thing?

Nope, not a "real" breed, but I do know they are breeding BC's smaller and smaller so they can run in lower jump heights.  When I was at the Invitational in 06, someone told me there was a BC in her area jumping in the 12 jump height.  I'd guess there are also advantages for smaller BC's in flyball.  BC-Jack X's are also common, again for flyball and nonAKC agility. 

 28 pounds is not undersized.  I have a friend who has a young female (looking for a home by the way, anyone?) that weighs about 25 pounds.  She's not super short though. 

I have a very petite female right here - I think she may weigh 22 pounds soaking wet.  And she is short, probably no more than 17 1/2 inches tall.  She is purebred fore sure, and bred for work, not sport - she is an import from Wales and is ISDS registered. 

And then there was the famous Jen.  She is also bred from working lines, and was 15 1/2 inches tall.  She wasn't dwarf, or stunted, she was perfectly proportioned, just incredibly petite.

Here's a pic I have of my normal sized BC Ben going over a homemade jump (these are the sorts of things you do when you have BCs - I practiced flyball in my living room!), and Jen going over the same jump - the two pics spliced together.

ETA:  Your pup looks like a Mini Aussie, actually - but it could be a mix.  Or, a Pom/BC mix.  It's not the size, it the shape of the head and the big eyes that screams "toy dog."

might he be a sheltie mix? 

 This topic makes me wonder, when does different sizing of a breed become legit?  When did miniature poodles, schnauzers, etc. stop being a breed aberration and become okay and accepted?

hmm... I guess I just thought he was much smaller than the normal because the bc pup we have now is about 24 lbs, and only 5 months old.

I had thought mini-aussie, but I didn't think aussie's came in black/white, but I haven't read too much into it. I thought maybe bc/sheltie mix, but that doesn't seem right to me.

He was a stray, so we have no idea what went on with him or where he came from. BC's are not too prevelent around here, so maybe he is an aussie. A friend of mine has a mini-aussie, and I suppose I can see the similarities between the two boys.

He's a great boy... I really want to keep him, but I can't take on another dog right now. Fingers crossed he gets a home this weekend!

I don't know about mini-Aussies, but standard Aussies come in what they call black bi.  Or is it bi-black?  My friend has one that is about 25 pounds - but she is not a mini.  Here she is with two of her long-time housemates:  http://www.angelfire.com/nc2/Mestena/index.html
 

hmm.... I looked up Mini Aussies, and Aussies - From what I could find, only the standard aussies can be black/white, not the minis. But I'm sure it could happen. Interesting.

Looks like a Sheltie mix to me.

 Given those p rick ears and the size, I'm thinking a spitz mix.

ETA: oh for goodness' sake, you can't say P R I C K?  LOL!

 Considering that mini Aussies are just small Aussies, it certainly is a possibility. I don't think he looks like a BC so much, even though have a wide range of looks just something about his head and expression don't say BC to me.

All those are shelties.  This is a sheltie mix that looks kind of like a border collie:

Not a Spitz mix (there are just not that many Spitz in the US- but there are millions of Big Poms of poor breed type which have reverted to the larger size and less toy-ish face of their ancestor, the Spitz)- but I'd not be at ALL surprised if that dog was a Pom mix!
