Dog Inter-Dog Aggression in Multi-Dog Homes

Inter-dog aggression in multi-dog households is a significant welfare problem for both dogs and owners - management and behaviour modification are effective.

Key Facts

Resource competition (food, space, owner attention) is the most common trigger
Conflicts often escalate at predictable times such as feeding and owner greetings
Separation during high-risk periods prevents injury while behaviour modification proceeds
Force-based interventions worsen inter-dog aggression reliably
Professional assessment distinguishes manageable household conflict from dangerous incompatibility

Welfare Considerations

Chronic inter-dog conflict causes ongoing fear and stress for all dogs involved. Early professional intervention prevents escalation to injury-causing aggression and reduces the welfare cost to all household members, canine and human.

What You Can Do

Seek professional assessment from a certified behaviourist early in inter-dog conflict
Manage feeding, greetings, and high-risk moments to prevent conflict opportunities
Never use physical punishment in inter-dog aggression situations
