Put them in separate rooms possibly, this way they can't eat eachothers food and try to dominate each other or fight.
they feel they need to be king they want to rule the house and give orders not be ordered around they think the other dog feel be boss not him
Dogs pee in their house to mark their territory.
female dogs are 'bitches', male dogs are just 'dogs'
No matter the sex, pitbulls are realiable house dogs.
Dogs don't spray like tom cats, but they will mark their territory with urine. They are less inclined to mark territory in a house once they are properly housebroken. Tom cats just can't help themselves--dogs can.
It really depends entirely on the individual animals. Typically, male dogs who haven't been fixed are more territorial than females, so based on that knowledge I would suggest a female. However, I have 2 male dogs and 1 female who all get along just fine in a house with a male cat. So, again, it just depends on the specific cat and dog.
you feed male cows (bulls) the same thing that you feed female cows so mostly grass.
Backwards, the same as the female. It's unusual in the mammal world. Usually the male urinates forwards.
Mostly good dog food that is made for small dogs. I also feed mine grilled meats (not fried). He maintains his weight between 4.1 and 4.5 lbs.
Male dogs can not go into heat.
Providing both dogs are used to other dogs being around them, yes. However, NEVER introduce the two dogs insde a house - introduce them somewhere that is neither of them's territory (a park etc.) before putting them in the same house together. Remember that an entire male and female will almost certainly breed so you might want to consider spaying/neutering if you don't want to breed.
Because they ARE male dogs. Have him neutered to control unwanted behaviors.
