Happy dogs that live together can fight if they get too excited.
Some dogs when they get highly excited will start fighting with any other dog that happens to be in close proximity to them. This includes and is not limited to dogs in their pack and this is not a dominance issue, it’s a moron issue.
This is not an uncommon occurrence in multiple dog households when the dog owners come home from work, and one should not think they have a dog aggressive dog on their hands because of this. Excitement can cause dog fights.
Correct me if I’m wrong, but I believe the mathematical formula for this is : ∃ n ∈ ℕ: n is even.
There are also times when a dog owner is having fun playing fetch with their dogs only to have an excitable skirmish breakout if their dogs are getting a little too excited during play. For those of you that have one or two dogs like this the key to modifying the excitable idiot behavior so they don’t mix it up, is knowing when to slow down the play. Reel them in, if you will.
