I have a male lab/chow mix that is about 3 yrs old. Have had him since he was about 6 mo old. He's been through odedience classes formal and Leerburg training informally. He is neutered.

Recently, my nephew moved in with us with his 15 mo rott, who has been informally train, and has had a good dispositon with my dau (8 yo) and I. He has never been around dogs before and has not been neutered.

The dogs seem happy to be together, but their play seems to be consumed with trying to hump each other. The rot has previously been an outside dog by necessity and we want him to be an inside dog. Right now we allowed my lab free reign of the house because he has always been an inside dog and the rot stays in the crate when we cannot watch him.

What are some of the steps we can take to tamp down this dominant pack behavior or should we keep them apart? Should we be concerned that these two dogs will one day turn on each other or even worse turn on us? My dau has played with each of them with no problems. However today the rot snapped at me while in his crate.

If you go to the information on Ed's website, you can get all the help you need with Dogs and Kids and Multiple Dog Households. The 15 month old Rot snapping at you does not sound good. Go here:

What were the circumstances? How long has the rott been living with you?

Thanks, Janice, for the direct link. I spent last night looking for it, but must have been too tired. I used this site alot when I got Sydney almost three years ago, but I hadn't been here in a while. At this point I have separated both dogs and we are starting from square one.
