A 50/50 mix of glycol-based antifreeze and distilled water is what you want. Not sure what you mean by 'dog-friendly', unless you want to feed the excess to Fido???? I would not put DexCool in your engine, as it was intended for use in aluminum engine blocks/systems.

If your intake gaskets have been replaced with something more current then pretty much any antifreeze on the market will work fine.
Just make sure the over flow tank/line are working and not leaking.

I use Dex-Cool in all my cars because I get it free at work. I never have any problems with it. Not all cars that came with it stock used aluminum blocks, in fact I would say a good majority of them don't.
