<human>: Hi, I rescued my Alaskan Malamute (Odin) last year, and he's a very calm easy going dog for the most part.  We've recently adopted a new Siberian Husky (Blueberry) who's more on the dominant and playful side.  It's been just over a week, and last night we heard them get in a quick scuffle outside, went out to check on them, and the new sibe had a decent gash right under her eye.  It's not bad enough to warrant stitches, and doesn't seem to be bothering her or causing discomfort, but we would like to hear if anyone else has had similar situations.  They've been playing well for the most part, but I can tell sometimes Odin might be wanting alone time or space when she keeps persisting.  Odin has never ever been violent to any other dog, and they play with their mouths a lot as northern breeds tend to do, so this could be just a case of playtime getting a bit out of hand.  Any advice would be appreciated.  My biggest fear is that Odin is lashing out because his world has been invaded by a new young crazy puppy, but I'm hoping it's just that they're being dogs and stuff like this happens.

Can you summarize the given text in a few sentences?
<bot>: Incident with new siberian and older malamute, where older malamute who's normally calm and passive gave the new dog a gash under her eye.  no stitches needed, but need advice.
