This corrections officer told police he was robbed at gunpoint after he went to see a man about a dog. Turns out he went to see a man about some pot.
The phrase "I'm going to see a man about a dog" means "I'm going to conduct some illicit business which I will not admit to". The response is "Don't let that dog bite you". In this case the dog did bite.
