My neighbor is moving they are an elderly couple and have 2 jack Russell which they recused 2 years back, The dog has not been socialized and are aggressive to other dogs and are afraid of people untill they know you then they are love monsters, so having not wanting them to go to a shelter I took them in But I am overwhelmed not only with cost but with how to move forward, some of there behaviors may be easy fixes I have no idea I will list what concerns me below ,
They Pull when walking, Like bouncy rabbits..
They are aggressive towards any dogs when out on a walk
They get jealous of each other always trying to get closer to me
There 2 1/2 years old non desexed
They Bark at people Dogs and at night ( Never Bite)
I would like to find a class to train them but am afraid how they will behave there ..
