change in behavior

Question
-------------------------thanks for the quick response Patt...In regard to your answer then...you are saying "if" we allow our DVO to breed we should then keep him and our other dog  Knight  separated,  or  should they be separated now....when neither have experienced breeding.  The younger of the two  Knight ..shows some aggression towards DVO....nipping on neck..when he comes back from a run without him..we think he is scolding him for leaving...but otherwise the two are left alone all the time and become upset when separated for any length of time...

Question -
We are thinking of mating our 4yr old male shepard but are concerned if it will change his disposition, or his aggressiveness with our other 2yr. old male sheppard.  We are also afraid he might run off when loose on our farm..to look for a female once he has his first experience at mating...

HI GAIL
A MALE NOT NEUTERED WILL SMELL A FEMALE IN HEAT SOME 3 MILE AWAY AND WILL ROAM AND TRAVEL.  THIS IS HOW WE GET UNWANTED PUPS THAT ARE PUT TO SLEEP MILLIONS A YEAR IN SHELTERS OR FOUND ALONG A ROAD.
IT SURE WILL CHANGE HIM INTO A BREEDING MALE OF DOMINANCE.  HE WILL BECOME THE DOMINANT BREEDING MALE AND I WILL NOT EVEN TRY TO PREDICT WHAT HE MIGHT DO WITH ANOTHER MALE.
GINO, MY BREEDING MALE DOES NOT GET PUT OUT TOGETHER WITH OTHELLO, MY OTHER YOUNGER MALE BECAUSE OF A FIGHT THAT COULD OCCUR AND I NEVER WANT A DOG FIGHT HERE.
U SHOULD GET A KENNEL TO KEEP THE DOGS IN DURING THE DAY AND IF HOUSE DOGS, KEEP INSIDE AT NIGHT.  U MIGHT NEED TO SEPERATE THEM ALSO?
GINO STAYS INSIDE WITH ME, OTHELLO IS KENNELED BUT LEFT TO RUN A FEW HOURS A DAY WITH THE GIRL DOGS.  HE GETS PLENTY OF EXERCISE, BUT WHEN A DOG IS IN HEAT THEY ARE KENNELED IF I AM NOT BREEDING THAT CERTAIN BITCH.
U MUST KEEP A MALE NOT FIXED UNDER CONTROL FOR IN TIME IT WILL RUN AND CAN GET SHOT BY SOMEBODY NOT LIKEING THIS ALSO?
SOME DOGS CAN BE BREEDERS WITHOUT CHANGING, SOME GET REALLY BAD.  DEPENDS ON THE TEMPERMENT OF THE DOG, TRAINING, ETC.

Answer
HI
ONCE A MALE BECOMES THE DOMMINANT BREEDER HE MIGHT BECOME MORE AGRESSIVE.  I WOULD CERTAINLY NOT KEEP THE TWO TOGETHER UNSUPERVISED TILL YOU FULLY TRUST THE SITUATION.
MY MALE, GINO I WOULD NOT TRUST WITH OTHELLO AS HE IS MY DOMINANT BREEDING MALE NOW UNTIL I USE OTHELLO ON ROSETTA IN FALL HEAT.
I DO NOT KNOW THEN WHAT TO EXPECT, BUT I SHALL BE SUPER CAREFUL AND NOT PLACE THE TWO BREEDING MALES TOGETHER.  NOW OTHELLO IS A BABY AND PLAYS, BUT ONCE USED HE BECOMES A STUD DOG.
