Dear emlaur; First let me say that I know how troubling this dilema is for you and yourr family. I hope your daughter is OK and your concerns are real and serious. I don't know if your springer has demonstrated previous aggressive behavior, or what the nature of her aggression is. But, due to the seriousness of the attack if you are not going to euthanize the dog, you need to seek professional help for this problem. There are vets who specialize in behavioral problems in dogs and I would seek there advice. Springer "rage" has been described in veterinary literature as seemingly unprovoked aggression and in one study elevated levels of serotonin metabolites were found in these dogs. Additionally it could be due to territorial or dominance based aggression. Typically therapy includes medical and behavioral modification. I would not recommend adopting out Molly. Consulting with a veterinary behavior specialist would be my only alternative to euthanasia for you.
