There is a dog in my flyball class who is aggressive towards men and kids (after being around this dog my thoughts that Frodo was HA flew out the window quite swiftly) and doesn't give any warning signs. She was a rescue so they don't know her past and her current owner uses a clicker and positive reinforcement, but she doesn't give ANY visible warning signals and seems at ease around them (no barking, growling, lunging) until they get close enough and then she just strikes.
It got me to thinking, if you suppress a dog's natural warning signs (growling, barking, etc) is there any way to reverse that? To get those signs back? Will they just come back naturally after a while, or are they gone for good? Ideally I guess you would just never put the dog in a situation where they would need to use the warning signs again, but I think that's often easier said then done.
TIA
