There is a distinct possiblity that it's a female husky thing--they tend to not like other female dogs. It could also be that Baby isnt' a baby anymore so Tikeya feels the need to assert her position more.

I know Great Danes aren't normally fighters, but I don't like the idea of letting them fight it out at all! Females fight to kill or at least seriously injure. The worst fights I'v ever seen and the most difficult to break up have been female-female fights. I'd say keep a close eye on them and separate them at the first sign of trouble. Maybe get a water bottle and give them a squirt if they start growling......

Good luck!
