Is it normal for dogs to suddenly get aggressive with each other after getting along for years?

My dogs have always gotten along really well, but lately, I've noticed some sudden aggression between them. They've never had issues before, but last night they started growling and snapping at each other out of nowhere. Is it normal for dogs that have lived together for years to suddenly start fighting, or could there be something else causing this change in behavior?

Answer

It's concerning when dogs who've always gotten along begin to show aggression towards each other. This change in behavior could be due to several underlying issues.

  • Sudden aggression may indicate health problems or pain.
  • Environmental changes or stress can contribute to tension between dogs.
  • Age-related or behavioral changes may alter social dynamics.

Dogs usually have a well-established hierarchy within their group, but changes can trigger unexpected behavior. This could be due to a medical issue such as pain or illness, which often leads to increased irritability. Alternatively, environmental factors like a recent move, a new pet, or even changes in household routines can be stressful for them. Lastly, as dogs age, their behavior can change, affecting how they interact with each other. It's important to monitor their interactions closely and consult a vet if their aggression persists.
