Advice please. My 13 yrs. Old dog is feeling sick. I've never seen him this way . Our regular vet is closed tomorrow and need someone ASAP in the morning that will see him without appointment and will not overcharge me. He seems hot like he running a fever , he tries to eat but can't keep it down . He will drink as long as I bring it to him in small cup. He's a spunky dog at his age and healthy, I just wonder if he's had a stroke through the night or if something else happened. Very sudden change . Thank you for any guidance . I'm in Westmoreland so any vet in the surrounding area Would be great .
