New behavior on his Birthday
So my little guy just turned a year old today. His new behavior is not wanting to get into the car. He is fine and then when he sees me near the car he starts to buck and pull back on the leash. Later today I was at the petstore and he did not want to leave the store doing the same thing like the car bucking and pulling back hard. He did that 3-5 times before I could finally leave the store. It was annoying and embarrassing since he has never done it before. Any idea why he would do this. Again it just started happening and this is right out of nowhere. He never showed signs of this.
He is not a rescue dog, he well mannered, and very well behaved with good social skills.
Thanks for the help.
