I adopted my dog about 9 month ago. He is a pitbull mix and he is 2 years old.
When I first brought him he was very afraid of everything and used to hide under tables a lot, but as time passed he became more confident around my family and in the house.
In the last 4 months or so I've noticed a strange behavior. Whenever we go on a walk he instantly wants to go home after he pees. We take 3 steps outside and he immediately turns back to the front door. Not only that, but if we don't go home he pulls so hard that it's pretty difficult to resist him. When I try to assertively resist he fights really hard and tries to get out of the leash (which he can't), and eventually has hard time breathing.
I tried a lot of different things.
I took some sausage with me and tried to give it to him as a treat for walking and not pulling back home. He didn't care much (though he really loves this treat).
I tried walking a little bit at a time, increasing the distance each time by a little, but it didn't work.
I ALWAYS try to be as calm and as assertive as possible so he can feel that I'm not tense and hope my energy can influence him, but every time we go outside he is just so afraid and so nervous.
I am really hopeless. He used to love going on walks and I used to take him on really long walks at least twice a day. We used to run together and explore new routes, but now it's like something changed in him.
I hope someone here can help me with this problem.
