What noise or water tactics work best for Great Danes?

How do I recognize a ‘puppy pass’ in young dogs?

Why do females have a higher risk of interdog aggression?

To safely interrupt a fight between dogs from a distance, the most effective water tactics include throwing a bucket of water, spraying them with a water hose, or using a full, unopened bottle of club soda or seltzer. In desperate situations, owners have even sprayed citronella, used a fire extinguisher, or pushed fighting dogs into a swimming pool. For noise tactics, a sudden, extremely loud sound, such as a marine foghorn, can startle the dogs into separating, though this typically only works once.

You can recognize a “puppy pass” when an older dog patiently tolerates a younger dog’s dominant or boundary-pushing behaviors without pushing back or correcting them. Signs that a younger dog is getting a pass include:

• Resting their head, neck, or front paws over the older dog’s back for an extended period.

• Humping the older dog from behind or over their head.

• Knocking the older dog down and lying on top of them, refusing to let them up until the older dog “submits” and stops trying to move.

Female dogs have a higher risk of severe interdog aggression due to natural canine evolutionary patterns that conflict with modern pet ownership. In the wild, female dogs typically live and work closely only with related females, such as their mothers, aunts, and cousins. However, pet dogs are typically forced to live with unrelated dogs, and this unnatural social structure can trigger pathological aggression in susceptible females. Conflicts between unrelated females can be exceptionally intense, as they are sometimes willing to severely injure each other or even risk their own lives to eliminate a rival.
