So, we're having some issues with Penny. Penny has been an only dog for all her life, until about 2 years ago when we got Daisy. She's always had some jealous tendencies, but I thought that maybe they'd fade away once she got used to having another dog in the house. However, that doesn't seem to be the case. It's extremely frustrating. Penny is tall enough to jump on and off the bed and couch no problem. Daisy on the other hand is too short and has to ask to get up and down. Well, Penny FREAKS when Daisy wants on the furniture. She barks, growls, lunges, just spazzs. Daisy has and will snap at Penny, putting her in her place. Daisy is not an aggressive dog whatsoever, it takes quite a bit to aggitate her, I can't really blame her for getting annoyed with Penny, but I do tell her NO! because it's not acceptable on either end. The barking is getting to the whole family. Daisy can barely move without Penny freaking out. The minute she hears Daisy's nails on the hardwood floor, it sets her off. Penny has always been a yapper, even more so than Daisy, a Chihuahua. I think she just likes to hear herself speak. I suppose kicking her off the furniture would help out the situation, but I work all day long and I know the rest of the family lets her on the furniture. Plus, when no one is home, she has free range of the house and spends most of the time of the couch or bed, sleeping. She doesn't have accidents or chew in the house, so I never really saw it as an issue. Plus, she's been used to being on the furniture for 7 years and we don't have carpet, just hard wood floors, so I guess she's likes the furniture because it's comfy. I always try to make sure Penny feels loved. I feed her first, say hi to her first, etc etc. I just don't know what else to do to keep her from getting jealous? There has been times we have Penny and Daisy have gotten into scraps, nothing too serious, but it's not something that I'd like to continue. They're okay with sharing bowls, walking on a coupler, etc etc. Penny just hates sharing the furniture.
