I'm probably gonna catch hell from yall on here but I had a dog that did the same thing but it was only with one other dog and they're around the same age (2ish). My dog was new to the pack and I guess he felt like he needed to establish dominance. Anyway, they start at it and we'd brake it up and then repeat cycle. Finally we let them go at it (supervised) on the way back to the truck. They went at it for MAYBE 10 seconds and broke themselves up. Now, they hunt together and get along great, you could put them in the same Kennel if you wanted.
