I agree that you need to be all over this until you have your dog in your possession. Focusing on getting your dog home safely seems to be more important than whatever compensation in a case like this.

As KLM is the handling agent for NW in AMS, you should place a phone call to +31 (0)20-6495168, the KLM Schiphol Animal Hotel
to make sure they are aware of your dog and that they have taken care of him.
If not, they may be able to take action locally to get your dog walked, fed and watered and to get you assurances and clarity.

You could also try to contact KLM cargo who are responsible for the animal hotel by general phone

Next time you fly with your dog, consider introducing yourself to the captain if possible when boarding or ask the purser to hand him a note explaining that you are travelling with your dog and appreciating him taking accountability for ensuring that the dog is on board and in a safe on-board environement before departure.
