Size of the dog in the fight 

The size of the dog in the fight isn't everything, but because knowing which limits are imagined and which ones are a reality is a factor, so is the size of a dog in a fight, to some degree. The size of the dog in a fight doesn't determine what the dog really is, that depends on the dog, not on its size. Weakness isn't a size based trait, and neither is how much fight is in something, those traits depend on the individual and not on the size of the individual. Not all smaller dogs have more fight than larger dogs, and not all of them have more fight than mouth even, it depends on the dog. The same is true for larger dogs. Not all larger dogs are underestimaters because they are larger. Recklessness and overconfidence aren't exclusive to only larger dogs, or only smaller dogs. It depends on the dog.
Size of the dog in the fight isn't everything, but it's a factor. Smaller dogs are not without faults any more than larger dogs are. Hopefully no dog loses it's humility and thinks it's changed into a different dog than the one it was as a pup, no matter it's size or experience (recent or past).

size run 

In clothing retail, a size run refers to a full set of clothing sizes. This can mean a range from XS-XL, or whatever that line of clothing’s size range may be.
We got 12 size runs of these hoodies in the middle of fucking summer, why does HQ hate us?!
