However, there's no definitive answer to which dog breed has the "biggest knot". It depends on how you measure "biggest":
* Size of the curl: Some breeds have larger, more pronounced curls than others. For example, the Old English Sheepdog is known for its large, bushy tail.
* Length of the tail: Longer tails with curls will appear larger.
* Thickness of the hair: Some breeds have thicker, denser hair on their tails, making the curl appear bigger.
It's more about individual dogs than specific breeds! A dog's tail curl can vary greatly even within the same breed.
