My dog will not eat or drink any water,for 3 days he is trying to vomit but all that is comeing up is thick mucus and he will not eat
Your dog might be drooling or salivating. This condition can be normal due to food stimulus and conditions like excitement & heat. If your dog was normal and all of sudden started excessive drooling then you should look for mouth, teeth, tongue, and gum diseases. Stomach disorders and metabolic disorders can also cause excessive drooling. If your dog is not eating and lethargic then take him to vet immediately.
