LABRADORS FIGHTING

Question
I HAVE A 2 YR. OLD AND A 8 YR. OLD LAB ,FOR SOME REASON THEY JUST STARTED FIGHTING AND WE CANNOT SEPERATE THEM. I THINK THE YOUNGER ONE IS GOING INTO HEAT  ,SO WE'RE NOT SURE WHAT TO DO WE DON'T WANT TO GET RID OF EITHER OF THEM.

Answer
Are they both female?  Sometimes keeping 2 females in the same house is difficult.  At 2, the younger one may no longer be satisfied with her position in the pack and be challenging the older one.  This is more likely as the younger goes into heat.  If the older one isn't spayed, doing so will help.  You should spay the younger one too, but most vets will insist on waiting until after it is all done.  

If she does come into heat, watch her carefully.  The second and third weeks are when the most risk of accidental breeding is. Don't take this lightly. She will do anything to get loose and get to a male. Once loose, an accidental breeding and an unwanted litter is far from the worst that can happen. Such breedings can also result in fatal infections. She can get killed when she dashes heedlessly across the road in front of a car. Other dogs or coyotes may kill her.

You can expect the same thing about every 6 months for the rest of her life if you don't go ahead and get her spayed. There is no other answer, and no good reason not to. Besides saving the hassles, it reduces the chances of cancer later in life. Please make life easier for yourself, her, and society in general by getting her spayed as soon as a vet will do it.
