year old female Chihuahua? We tried introducing them once and it didnt go well. My Chihuahua (peanut) was the problem. The american bulldog (legend) had no issues with her, but peanut growled and nipped and him so we seperated them before Legend had any time to retaliate! Peanut has never had any problems with any other dogs before but for some reason she did not feel comfortable around Legend. My bf and I are moving in together soon and we need our dogs to get along....please help!!!!
