Instructions
Set an appointment with your veterinarian to have both male dogs neutered. Neutered dogs tend to show less signs of aggression toward other male dogs.
Modify the aggressive behavior between both male dogs by enrolling them in a training class designed for aggressive dogs in one household. An example of a class is a "Growl Class." This will aid in positive steps to take in avoiding aggressive behavior or injuries.
Feed the male dogs in separate areas at the same time. This will prevent any fights over possession.
Reward the male dogs with treats only when they both have exhibited good behavior or have listened to a command. Do not throw the treats to them but hand the treat directly to each individual dog after he has obeyed a command. This will prevent them from fighting over the treat.
Prohibit tug of war and wrestling between the two male dogs as this can often lead to a fight. Play with the dogs individually and in separate locations.
How to Get Two Male Dogs to Get Along
Male dogs are typically territorial and live by the rule of rank. The top dog or alpha dog is ruler of the house in a dog's world. When a new dog is introduced, especially another male, this role is immediately challenged. Safety of your pets and your family depends on the compatibility of your two male dogs.
