Canine Penis Size Comparison

always look at the dogs sheath and add an inch or two plus the knot
That is definitely not an accurate way to assess a dog's erect length. Most dogs have a long enough sheath to accommodate a full erection, with no more than a quarter inch of their head protroduing. Some have enough prepuce to completely house a full erection. The only way to know for sure is to fully unsheath them and measure.
 
The average large breed dog (70+lbs) is more endowed in length and girth of the shaft than the average human man.
I would rather say that if the dog is large in length, the longer its dick, having seen large dogs, even heavy ones with an average dick
 
Slowly filling in those measurements *if they are real actual measurements i cant guarantee!* But i try fill in measurements as soon as there comes new measurements!

Keep your measurements coming.. 'and keep them real and true!'
Never measure as we guys do.. By adding a little to make i bigger! 😉
This chart is for scientific use for all members here! *i hope!*
Are the length measurements including the knot?
