My cavalier just turned 3 in January. He was fixed at 5 mos old. I also have a male Shih tzu who is 2 years old. They are buddies. HOWEVER, I have never had this cavalier breed and I am not sure I am liking it. He wants to hump my shih tzu a lot of the time. He also sticks his pee pee out REALLY FAR when I pet him...no matter if it is just on his head or ears. It is really weird. AND sometimes he even gets so excited he starts jerking his back end and can't control it. At one time I asked my vet about it a year ago and he said he would grow out of it...but he hasn't. At that time we even tried this hormone...elvil..or something....to see if it helped. It did a little...but he was very thirsty on it and almost too tired. He is a sweetie and I want to keep him but this weirdo behavior on top of us having 4 kids and one other dog....is freaking me out. Any thoughts or ideas??? Thank you so much. Jan
