My advice is that they bring in a professional. They should hire a one on one trainer. Whenever the underlying issues stem from the owners not defining themselves as the alphas in the pack, much of what they can do that would normally help, will wind up only confusing the issues more.
In general, the alpha hands down a rule, and it is obeyed by the pack. But when it's just another pack member handing down a rule, it can be seen as a challenge, and cause a dog that is vying for that alpha position to fight even harder to assert himself. Really, anything they try prior to establishing the correct roles can wind up backfiring.
Bringing in a professional trainer will help train them on how to assert themselves as the alpha members of the pack. The training, though posed for the dog, is really for them. Afterward any tricks or tips relayed have a chance of working.
Your friend could try obeying the local leash laws.
I've never seen or heard of a better "dog trainer" than Cesar Millan, the dog whisperer. For any type of behavior, or advice.
He's got a TV show as well as books and videos. People may think he's a miracle worker because he's so good. But the fact is, he knows dogs .. one of the best on the planet.
They will stop chasing cars when the car stops.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
