Hes a labrador. Everything is going well and all but i am a bit shocked at what happened today. Its only the first day we had him. Hes around a year and a half old. He gets on with us well and is friendly. When he was left alone with me, he was wimpering a bit because the rest of the family was out. I was stroking him. He kept trying to jump up on my and lick my neck but it wasnt like a normal lick, he was trying to sort of pinch my skin between his front teeth like he was nibbling. He was wrapping his front paws around me, my leg my arm whatever he could get hold of and rocking his hips. His little penis kept coming out and he got a bit wet. I kept pushing him down to stop him. Ive never seen this behaviour in a dog before. He is pretty forward thats for sure. Im worried he will do this to others.
