 PetSmart tells 7 News in an email that the death of the dogs may be due to underlying health conditions unrelated to the dogs' stay at PetSmart. Animal Control says that the Aussie Doodle's body is currently undergoing an autopsy. The two other dogs that died were cremated. Animal Services is interviewing employees and says that PetSmart is cooperating with the investigation. Alexandria Animal Services has been visiting the hotel every two days since the first report.
