This invisable fence thing is killing me!!!! Chloe is occasionally runnig through. She would wear the batteries down and off she would go so we bought a new collar for stubborn dogs. Well my house keeper saw her run right across the road,(55mph) she brought her back then we check the collar yup it works. I looked out later and she is in the neighbors yard. I grabbed my coat and shoes went to the neighbor no Chloe. They said they saw her go across the road. I went over and there she was in the back yard..... chasing chickens!!! She was not barking but the bird was clucking like mad and she just chased. She was right on it but did not bite at it just ran. The chickens owners where not worried about Chloe hurting the chicken they would attack her if she irrated them enough her Jack Russel learned by the chicken not taking it any longer. She was worried about Chloe crossing the road. But when she was chasing she shut me right out!! She didn't listen to my commands.Any ideas?
