RE: how old is to old to breed?
IF YOU FOLLOW THE RULES AND WHAT ALOT OF VETS SAY, THEY WILL PROBABLY SAY 7-9 IS ABOUT IT. I AM NOT SURE. I HAVE BEEN BREEDING FOR A LONG TIME, AND HAVE BRED MANY 9, 10, AND 11 YEAR OLDS. I JUST BRED A 13 YEAR OLD BITCH , A COYOTE HOUND, AND SHE HAD 8 PUPS. THEY ARE 9 WEEKS OLD AND NEVER LOST A ONE.
