This is SO frustrating for me. I have had and trained dogs for years and never had one I couldn't do a thing with. Until this one! I have 3 dogs. One 65 pound female pit pull who is brilliant, easy to train and eager to learn. I also have an 8 pound long haired chihuahua who rarely ever gives me any trouble. And then there's the problem dog, a 3 pound long haired chihuahua named Lucy. Lucy yaps. I let the out to go pottie and she hits the ground yapping, chasing shadows, yapping at the moon and basically getting everyone else charged up. She is not a smart dog, but is so adorable she has been allowed to get away with not knowing anything for a long time. She is not leash trained so taking her out to go pottie on a leash isn't going to happen. Like I said...she is not smart. She had hypoglycemia problems (including a couple bad seizures) as a small pup and I honestly think it damaged her brain. It took 8 months to house break her and I am good at housebreaking dogs! I am getting an Anatolian Shepherd pup later this summer and don't want him to pick up her yapping so I need to break her of this ASAP! I am considering a small E-collar for her. Innotek has a very small one that will fit her but the range is quite bad. Anyone know of another E-collar that will work on a tiny dog? Or any other suggestions for me? I have to get this stopped! Thanks
