Alpha Elite K9Logo Design Contest

Your Dog, My Problem

Training protection dogs and dogs in general

Red - Main color, I want to convey High-End, Powerful, Protection Dogs
Black - Secondary main color
Blue or Purple - Not the main color possibly accents
White or Gray - Background, not main color

Sorry they are slightly out of numerical order.
Either the look of the dog in reference10 and reference9 where they are actively looking to bite or that of reference8, not exactly like reference8 though, the head needs to convey more of an intimidating look that gives off serious vibes.
Looking for the logo to be of the head only, neck and head would also be acceptable.
Nothing with to much details more of an outline like reference5. The head should not be of a happy dog. I am not training pet dogs. I am training dogs to protect. Probably have the head slightly upward and with an intimidating or ferocious look.
If you could create the outline, ex. reference5, with more individual sections so there can be less of one color and instead have a main color that does overshadow the secondary color.

I'd like the font for the "A" in Alpha, the "E" in Elite and the "K9" to be a "chunky masculine" font. (so that I can use it with the dog logo and AEK9 below the logo (like the red and black circular logo attached). I also like the blue circular logo with the whole name written out in the outer circle.

The red in the red and black circular logo is too much. It's too bright and gaudy. I'm looking for a deeper red. More professional -- black, silver (maybe white) and darker red accent.
