Bear was doing much better the next day I did contact the vet and he said to wait till morning to see how he was doing. We are still not sure if it was the heat or he ate something bad. His stomach was not right for at least 4 days(alot of gas). But I am pleased to report, he is happy and himself again.
thanks everyone
I agree with peek about the bloat. It seems like it happened so fast. Could he have eaten something toxic?
IMHO, you should get him to a vet asap.

Definitely check his gums...grey to white means in shock. Please contact your vet asap!
You may be looking at heat stroke. Get him to a vet NOW! Heat stroke is a medical emergency, and death can come quickly. Soak him down with cool water before you get going. Check his gums - if they're white, he is in shock and you have no time to waste.
How is he now? He could be bloating. I'd get him right in to your vet if he's not improved.
