I’ve been a dog owner for 25 years and I’ve worked in an animal shelter. I can tell you that dog was not aggressive. That dog was going up to him to be petted.
Had this a K-9 officer he would have known this.
That cop was just being an asshole, in my opinion.
Agreed that dog was not showing signs of aggression, however for someone not familiar with dogs they could easily react to any animal coming at them as a threat.
