What caused the fight if I can ask?
food, attention, or they just looked at each other and said, "why are you here"?
There is often a "squabble" or 2 with new dogs..just learning their place.
Its helpful to know if you can see what triggers it..
@drummamamma:
My other dog ate my sons retainer twice. There must be something delicious about the inside of his humans mouth to a dog! Yuck! ha ha
They like it because it's expensive.
