What is his Tempture and also what color are his gums.

I really would get him back to a vet right away MY Denver acted that same way very lathagic and not wanting food or water and kinda stayingaway from us laying in the kitchen by himself i figured it was just because he was sick and did'nt want to be bothered so i took him to bed with me and 3 hours later i woke up and he had passed away.

I REALLY REALLY WOULD GET HIM TO THE VET ASAP
It does'nt sound to good if he's acting the same way so get him there ASAP PLEASE !!!!!
