Have two GSP, male and female, fixed the male at 8 months old and spayed female at about 6 or 7 months old. They are now 9 years old for the male, weighs 74 lbs, washboard stomach and all muscle, the female weighs 68 lbs also thin and long and all muscle, she did develop incontinence her 4th year. I give her cranberry supplements and it seems to work most of the time unless she is extremely tired and hot after she has been running a lot, when she cools down she's dry. I also feed them turkey low sodium hot dogs for dinner every day unless we have table scraps or game liver, heart, kidneys and scrap meat which they love.
