I think a lot of people get a male dog that is not housebroke confused with a male who is marking. Males that mark go around constantly hiking their legs on things, often when they don't even have have any pee left in them. A male dog that is not housebroke will hike his leg on something just when he has to pee. Male dogs that are marking tend to do that behavior more when there are females in the house that are in heat. My dogs are potty pad trained but the males do like to hike there legs so to make it easier for them I take a laundry detergent jug filled with water and sit it in the middle of the potty pad and the males pee on that, kind of like a fire hydrant.
Sadly, besides neutering, there are many things we do to our dogs that can effect their health and well being. Rabies shots can cause many side effects that people are not aware of:

Flea treatments and heart worm medications also can do harm to our babies. Life is full of difficult choices and sometimes it does get confusing as to what is the best thing to do. Some dogs will do well and some will not. When you combine together all the things we are subjecting our pets too it is no wonder that many of them have serious health and behavioral issues.
