DALLAS — Note: An earlier version of this story stated the pack mates were Ola’s brothers. This information has been corrected.

An African painted dog was found dead Thursday morning at the Dallas Zoo, according to Twitter.

The Dallas Zoo shared the news in a tweet, stating 8-year-old Ola was killed overnight by her pack mates.

Zoo officials confirmed Ola died from the injuries she suffered during the aggressive attack.

The pack mates were brothers and 2 years old. They were introduced to Ola three weeks ago and everything had gone smoothly up to that point, according to the Dallas Zoo.

The zoo went on to state that the brothers did nothing wrong because the dogs were “only exhibiting natural behavior.”
