Hello everyone, I have a six months female samoyed and from the beginning she was hard work. I used positive training and done everything with nothing in life is free, sit before feeding, giving a toy etc. She is over excited, reactive and a nervous dog. I've exercised her, she runs in the fenced park and I've played fetch, played hide and seek, put a towel to find treats but still she can't calm down. Walking her is awful, now I have sciatica and really don't know what to do because her reactions toward everything is abnormal she jumps during walks from left to right and backwards, if I change direction she pulls even more, If I stand she whines and barks and she can't settle down, nothing is working. For three months I didn't allow her to jump on people when walking on a leash, and she still does that to strangers who does not even look at her and I had awful argument with a man because she just jumped on him and scratch him and I really understand that man. She is rude towards other dogs which result in other dogs growling at her but after that she still continues to lunge at them and barks. I socialized her with some dogs from my friends but it still seems that she is afraid of other dogs but still lunges and stares and tries to do everything to come to the other dog. I potty trained her with treats, we have a yard where she can pee and she peed in the house yesterday even the door was open. She sleeps in the house with me I love her but I don't know what to do. From my perspective she is not a loyal dog, I think if I would let her to go to any stranger she will follow him regardless of me of any treat. Any advice is appreciated.
