I am not trying to be funny or anything, but Chilli had just started to want to hump my leg. He started it yesterday and he did it again today. I was playing with him and his toy, and all of a sudden he starts it. He did it to me again today with my arm. I hate it when he does it and I say NO and shake him off. Is it hormones? He is just around 18 weeks and we are getting him fixed later on this week. Is it good that I am saying NO and shaking him off, or should I do something different?
