Thanks everyone. Just came back from the vet. He has worms/parasites.
We just moved with my grandmother temporarily and I believe he got it from the backyard...eating stool or getting to stool from another dog who was probably out there and infected. In addition to that he got it from eating stuff off of her floor. She tends to eat in the livingroom
and that is where he likes to roam. Plus I didn't give him his heartworm medication this summer...didnt think I really needed it...so my fault on that one.
He had 3 shots and the vet gave him some food to eat for the next few days until his stool is back to normal. We have to go back in 3 weeks for another heart worm shot. I will be moving next week to Washington D.C., now I have to find a vet there and set up an appointment for an evaluation. Another thing added to my laundry list of things to do!!
But it's cool, I'm glad we caught it. He ate his food and is sound asleep.
