Hmmm. I wonder if its is just a dominance thing. The two pups I have are very different. One is very dominant and the other will just go with the flow. The one doing the humping is the of course the dominant one. All I've found on this is to distract them when their doing it but how do you watch them 24x7
I guess I "expected" this out of a little boy but not out of any of my girls...so of course we couldn;'t help but chuckling at first.
Oh boy
