How can my friend get her her rescue dog Jack Russel rescue dog to stop being extremely agressive?

Sounds like your friend has a problem. I had a foster dog that was aggressive with other dogs but great with people. I had to bring in a professional trainer (well the humane society sent the trainer for free), but the dog never got over the aggressiveness.

Her little dog is going to need loads and loads of socialization. She is certainly going to need a trainer FOR SURE, and that would be my 1st step.

Also, make sure the dog is put up so he cant escape anymore. If he happens to bite a person, your friend is going to have serious problems and her little dog is going to probably be put down.

Russel is not my favorite dog the fact that he is adopted leads me to believe that someone else gave up on him. They look cute and people think they can change them or make them a nice dog but thats what he is so she better love the little guy because she will never be able to let him off a leash. My favorite dog as a kid was a Manchester Terrier named Tiny that little dog knew no fear and would fight any other dog it either liked you or attacked just the nature of the beast.I wish your friend well maybe call a few pro dog trainers but I fear he's set in his ways.

the 1st ingredient you will desire to do is get a vet verify as much as rule out scientific issues, an 8 year previous dogs, is seen a geriatric, previous age, dogs. as quickly as this has ruled out any available scientific reason for the habit you will discover between the various domicile preparation methods and initiate from day one, i advise employing a restrictive technique like crate preparation, or confinement to a piece which will make sparkling up of injuries effortless. then set a ordinary for potty breaks. because of the age of the dogs she will possibly no longer make it to a level maximum persons would be soft with. yet she would be in a position to strengthen. make going potty a close-by constrained habit, or placed it on comand with the help of employing a key be conscious or word like circulate potty. because of the fact the dogs starts off to pee or poop. in time with staying power and consistancy your dogs will study that it has a particular place to circulate potty and/ or a key be conscious which will sign it to circulate potty. yet differently to get help is to speak on your vet for a referance to a close-by dogs coach to artwork with to sparkling up your issue habit.

TRAINING is the key.

Your friend needs to find a good trainer and work with him/her to train the dog and specifically work with his particular issues.
