IMO this situation is mostly found in breeding situations or intact groups...I have never had a male and female fight, rarely had spayed bitches not get along...I have had them growl, snap or be short with each other, but never actually fighting. If you S/N your pets at 6 months or so, you should not have a problem. If you bring in a puppy when you have an adult, there is rarely any fighting...bringing in another adult can be dicy..but with all the dozens of Yorkies I have had of all agea, I have had few who fought.
It is common for bitches to fight when they are confused as to who is the alpha bitch...
The fighters I have had was due to a bitches "alpha confusion"...I learned to become the alpha bitch and that really brings fighting to a halt..but it did not stop a few bitches from deciding they did not like another for any number of silly reasons...I would tolerate a bitch singling out one she hated, (I had room to separate them, indoors and out )but never a bitch who was aggressive to all or even several...I have never had a Yorkie who showed any aggression towards humans..if they did, they would be S/N asap as I do not think they would be suitable for breeding...
If the owner asserts themself as the pack leader, the dogs rarely fight I have found. |
