Sibling Rivalry

Sibling Rivalry can occur when two dogs compete for dominance, where the two are so equally match neither one can dominate the other without a fight occurring, if neither one will passively submit the fight for dominance will escalate.
Sibling rivalry occurs around the time of the dogs sexual maturity (the equivalent to our teenage years). As the urge to dominate grows stronger the fights become worse and more frequent the damage may worsen every time as the want to be alpha (pack leader or however you like to label it) intensifies. A wild pair of dogs would fight for dominance over the pack until one submits or is severely injured.
Joanna and myself always discourage people from getting two dogs from the same litter to avoid the possibility of sibling rivalry. If you are experiencing the problems associated with sibling rivalry the issues can be resolved with professional help.
I am not saying do not have more than one dog. I am however saying before you acquire your second dog make sure the dog you already have is trained and behaves exactly how you want it to. If it does not you will only be doubling your problems by introducing a second dog to the household.
When buying a dog or another dog ask yourself are they the right breed for me? What dogs will be compatible? Will these dogs work with my life style? When choosing a dog or any number of dogs, think, best of all seek professional advice. If done correctly a pack of dogs is a joy if done incorrectly a pack of dogs can be a nightmare that can turn into a blood bath.
