8 police dogs headed for training die after AC failure in transport vehicle

Nineteen police dogs being transported from Chicago to a training facility died or were injured when the AC failed.
The dogs were in a truck for over 2 hours when the AC broke down, causing the temperature to fatally rise.
The driver pulled over when hearing distressed barking but 8 dogs had already died from heat exhaustion.
The incident was caused by an AC malfunction rather than neglect or cruelty.
Some surviving dogs were taken to an animal clinic while the deaths are being investigated.
