I called before when the dogs they had previously were mean and would chase my kids. I started keeping the kids inside and we went elsewhere to play outside. Ridiculous I know but hubby INSISTED I not start trouble since they were here before us. I called animal control, the guy said I had to prove they were dangerous before he could do anything. The dogs attacked my in-law's dog (not the first dog to be attacked, they killed the other neighbor's dog) and my FIL told them they had 2 days to get rid of them or he would. Animal control came the next day. I just assume that the same thing would be said.....prove they are dangerous or eating eggs/chicks.... hard to prove on the spot.
