Took my dog for a walk and his breath sounded weird...like a cough that wouldn't come up. Then after a few, I noticed that he had drool...long like strings coming from the sides of his mouth. Carried him back, tried to get him to drink, but he wouldn't; He's now laying down (looking ok) but didn't know if I should be concerned on the drooling. It was thick like, and white in color, and I've never seen it before.
