My Dog Has Brown Mucus Running Constantly From His Nose. He Sneezes, Coughs, And Vomits Brown Mucus Every Couple Of Minutes. He Won't Eat Or Drink, And Is Very Weak. What's Wrong With Him?

Evidently your dog is very sick - and, if the symptoms are as bad as those you have described in your question, then my advice to you would be to take your dog to the vet immediately.

A vet will be able to carry out a detailed and thorough examination of your dog, and can hopefully establish what is wrong with your pet very quickly.

After the initial diagnosis, the vet should then be able to start a course of treatment right away, hopefully ensuring that your dog will be back to good health in no time at all.

My dog has brown mucus - what is this a sign of?
Brown mucus could a sign of a number of issues, such as:

• Brown mucus can be a sign of heart worm. You should be concerned about this if your dog doesn't take a heart worm pill every month.
• Your dog could be experiencing other heart problems or upper respiratory problems, such as lung worm, or a fungal or bacterial infection.
• Dog flu and kennel cough could also be causing these symptoms.

Your dog is obviously in a great deal of discomfort and needs to be taken to a vet immediately.
