A special type of perseverance displayed by a young pet, especially a dog, marked by a steadfastness in the act of urinating numerous times on its training pad in order to obtain as many rewards as possible such as a meaty treat or bone, despite difficulty or delay in achieving success.
His dachshund's pisseverance illustrates its single-mindedness to get lots of treats. In the course of one day, it drank 10 gallons of water and always held some back each time it pissed so it could turn the next pad yellow at will. Now that's not normal doggedness. That's pisserverance!
