QUESTION: sir, thanks for the answer. did you mean sloshing noise coming from horse body? if yes, may i know why only sloshing noise? why not other kind of noise

Answer
hi --- when the horse is in motion i would expect the testicles to be drawn up  so that they DO not hang down and bother the horse when galloping or racing. just talk your rider to listen to see if they hear any odd noises when galloping the colts.  thanks ED HESS
