not sure about the rage thing,that term is used far to much in my experience
i was told by our vet,and groomer what was i thinking getting a cocker with kids for, especially a solid black
as she was almost definatly gonna get temprement problems.cant tell you how upset i was, i think it ruined my first few months with her worring about it
what im trying to say is please dont take the term "rage" lightly from what iv learned it is a very rare thing now,i hope you get to the bottom of mollys problems,ruby sends cocker kisses to you both
