Hi all, I'm currently fostering a Chihuahua for a local small dog rescue. She's your "typical" yappy, barky Chihuahua and I want to train her out of this behavior (I put quotes around typical b/c I know not all of them are like that, but it's a misconception). She is seven years old - is she still trainable? I've been told by the rescue that she has been allowed to bark at visitors, dogs outside, and other strange noises from her previous owner. It gets pretty annoying, esp. when we're out walking and she yaps at other dogs. I have a Maltese and never had this problem, so not sure how to fix it. (Did also another Chi of my own who since passed away but I finally found something that worked and was able to nip the problem at the bud) At least one interested adopter has turned down adopting her because of her barking when she visited. She will bark and bark and bark until the visitor stoops down and pet her. Once they stop, she will bark again. As soon as they move, she will do it again. If I keep her in the bedroom, she will bark each time she hears the new voice and can do it for hours (no kidding). Can anyone please help? She is otherwise a nice dog and I want to help fix this so she can find her forever home. So far, I've tried: spray bottle getting her to stay quiet and then treating, but as soon as she gets the treat, she'll go right back to barking have everyone ignore her isolate her in a room when she barks and only letting her out when she is quiet, but she'll run straight out to the visitor again and bark once she is released I'm at my wit's end. Thanks for any comments!
