Ugh my dogs have gone from over protective to please break into my house and kill my mom. I have two old bichons that when they were younger were the best watch dogs in the world. My border collie cross just follows what the other dogs do and my lab use to scare me with his protectiveness. He would almost go through the windows. Now people can pull up in the drive and walk to the house and they don't even bark!! I hate it. I am alone a lot and i live in the boonies. How can i get them to alert again. Ive never had this problem before. This has all changed in just the last few months.
