So, I have always known that corgi's have big attitudes and they get jealous easily. We have a routine around here, Copper and I. He even has his routine with Scott (my bf). He is not happy about this overnight guest. In the mind of Copper, Jasper is taking his attention and love and trying to steal all of his toys and worst of all, Copper had to be locked in his cage last night. He wasn't bad and I cannot even tell you the last time I locked him up because he doesn't need to be. The thing was though is that I thought Jasper would fit in his cage and he didn't. He was WAY too big and he had also grown since the last time I had seen him. Mind you, we live in a little apartment/efficiency and it wasn't like I could lock one or the other out of our room. So, at about 10:30, neither one of them would quit instigating the other and Copper was ready for bed but had to keep making sure Jasper wasn't playing with his toys. Jasper was fighting the sleepiness and Scott and I were ready for bed. So, as bad as I felt, Cop had to be locked up so they would calm down. He wasn't happy about it and I was really proud that Jasper slept pretty much through the night. He didn't chew anything up, didn't whine, didn't have any accidents and I even got up at 3:30 and let him out. He got a little restless after that but then he was fine. To get to where Copper is a bully, he won't share his toys for the most part. If Jasper even goes near his food, forget it. Jasper would share his food willingly without a peep but not Copper and when Jasper went to go see Cop in his cage, Cop let out a mean growl. Jasper is easily two times bigger than Copper and Copper bullies him and Jasper takes it. I think Copper is having a hard time getting used to there being another dog in HIS house with HIS mom and dad. He has been really snappy at Jasper, no one else, and he has no problem telling Jasper "back off". He doesn't really ever act like this except at my ma's house when he has his own bone and my mom's black lab tries to bully him and take it. I honestly think he's just been bullied and he's fed up so he thinks it's ok for him to do. Has anyone else ever had this problem? It makes me feel like I failed at raising a well behaved boy.
