Sounds like you might be describing Pinstripe motley (if all or most of the dots are connected into a stripe) or Q-tip motley if groups of two dots are connected (making a Q-tip shape). If you have a picture as an example, that would help.
Classic/standard motley - this is the connected saddles down the back forming circles/dots. Level of expression does have a selective breeding quality to it
Hurricane motley - this is a classic motley with frosting in the saddles causing the color to ‘concentrate’ around the dots, forming a ring
Q-tip motley - this is where some of the circles in the classic motley start stretching and connecting with one another, 2 to 4 spots at a time
Pinstripe motley - most or all of the circles are connected, leaving a narrow line down the spine instead of the typical circles
Banded motley - instead of forming circles at all, the saddles stretch downwards to connect to the belly
Leopard motley - rarest pattern, looks like what would happen if you tried to have a pinstripe and a banded motley on the same animal. The pattern is relegated to large blotches on the side with no pattern over the spine
I’ve often seen the dotted motley pattern down the neck, but they seem to stop connecting around the back area.
For some reason, I haven’t seen too many “dots” continuing down to the tail (although I have seen some.)
Since I know hurricane is bred for, is this neck to tail classic “dot” motley pattern bred for as well- or is it usually just “whatever pops out- pops out”?
I think that this used to be more available. I seemed to see more of them, say ten years ago. It seems like it’s something which could be selectively bred, just as the hurricane pattern can be selectively bred. I have seen the term “polka dot motley” used for individuals with this pattern.
