Where does “collie” come from?

I need to note that the etymology chain provided is for "coal," not "collie" (which is a dog breed). Additionally, the chain shows "gel-" repeated three times, which appears to be an error in the source data. However, I cannot write an accurate etymology for "collie" using this chain, as it doesn't match. I also cannot write a sentence stating the coal etymology for the headword "collie" as that would be inaccurate. Could you clarify: Should I write the etymology for **coal** using this chain, or do you have the correct chain for **collie**?
