Actually not totally true. This doesn’t state what kind of spaniel, wish it did, but I’ve had spaniels since 1979 and we had one we adopted who had been badly abused, had two broken ribs when we got him, and that particular dog was badly affected from both his past and — as it turned out — from the rabies vaccine required by law. It took years, but finally even our vet agreed there was a link as we noticed with each vaccination his disposition got worse and worse and worse.. there was more that eventually even brought our vet to the same conclusion we had drawn, but that is all off topic this article.. this particular dog my husband could handle, but if I even looked at him sometimes he would lunge at me like he wanted to attack, I could not put a leash on him, etc... we probably should have put him down, most would have, but we kept him till the day he died and he is one reason I am VERY careful where I get my dogs and how I care for them. We knew someone who had a Springer who had what they call rage syndrome.. that dog was put down, I used to see a lot of stories like these on the cocker forums... it really makes you count your blessings when your dogs have the sweet disposition a cocker is supposed to have, but I blame a lot of their problems on back yard breeding and think their issues are 180 from pit bulls.
I agree. See my post 7.
Overbreeding has created some real problems in cockers. Sad as they are my favorite dog.
