I have two boars, Sparky and Scampy-Joe. Sparky is 4 and Scampy-Joe is 8 and half weeks they are closely bonded but I keep hear one of them rumbling at the other (I am not sure which), I always associate rumbling with aggression yet there doesn't appear to be any. I have witnessed them when one of them is rumbling however their is no aggression. Any ideas?
