I agree, if you only bought a pup, then you owe nothing.
If Hueblot bred to the man's stud, and got pups, he owes Kimo for the breeding. End of story.
If Kimo lied about his stud's exploits, Hueblot should have done his due diligence before breeding to the stud, but that would still make Kimo a liar.
I understand Hueblot just "trusting" the guy ... same as I just "trusted" that Ch Hammer was really off of BBB ... only to find out 12 years later, he was not.
Worked out all right though
