Molly is 7 yrs old springer; rage or cannine aggression syndrome usually begins at an early age as it is a genetic mental defect.It is not only found in springrs but can affect any breed of dog.I would check medical problems first and also the dogs pedigree contact your breeder and ask them if any other of their dogs has shown this problem.Most rage in springers is in the show and or half show half field lines it is very rare in 100%field lines.There is no cure for rage and no amount of trainning can eliminate it a dog that is properly diagnosed with rage can not be trusted and must be put down.In over 25 yrs of guiding,trainning,hunting,judging and trialing springers I have only encountered 2 rage springers one was a 6 mo old show prospect the 2nd was about 2yrs old show dog and the third was a half show/field dog that I refused to train all three dogs were eventually put down.The springer is esentially 2 breeds the field style(which is the best) and the show or conformation type which sometimes gets too closely bred to conform to the breed standard for show springers.But as I said earlier get the dog checked out first then if rage is the blame put your heart away and do what must be done.Fielddog(Mike) Byonderbrae fielddogs
