I know this is going to sound funny but any one who has a male yorkie can answer this. My male just started trying to "hump" my arm last night while we were in bed.

I was just wondering if it was normal for him to start doing that at 4 1/2 months old?? And if it is how can I get him to stop besides getting him fixed? I don't even know how old they need to be to be able to get "fixed. "

Any help would be greatly appreciated!!!
