Multi-dog households create welfare opportunities through social enrichment but require careful management to prevent conflict and ensure each dog's individual needs are met.
Multi-dog household welfare depends on compatible pairings, adequate resources to prevent competition, and owner attention to each dog's individual needs. Chronic low-level conflict between incompatible dogs reduces welfare for both without being obviously visible to owners. Ensuring each dog has individual feeding, resting, and attention time prevents the gradual welfare erosion that occurs when resources are shared by incompatible animals.
