Reply #37: My two dogs ( Both neutered males) will go at it with growls and squeals,

[hedgehog]

then both stop abruptly to make sure that no on eis running a can opener. Other times it's as if they've heard a bell; they stop in place, look around, catch their breath and go right back at it.They will roll around and thump the side of the house so hard the wall shakes. Neither has ever drawn one drop of blood from the other. It's just what dogs do. Cats do the same thing, but they are more quiet about it. A playful kitten is actually practicing the moves that will turn it in to a rodent killing machine.
