Don’t hesitate: If you see these symptoms, get your dog to a veterinarian immediately!

Swelling of the abdomen
This is the primary symptom of Bloat, which can kill very quickly. Bloat happens mainly in deep-chested dogs, such as the Basset Hound, Great Dane, and other large breed dogs.

Unprecedented convulsions
What Does a Seizure Look Like?

Unconciousness

Laboured breathing

Bloody diarrhea

Difficulty, or inability to urinate

Uncontrollable bleeding
If your dog is ever bleeding heavily, and the bleeding does not slow down right away, please take him to the veterinarian immediately to have his injury taken care of.

A dog can die of blood loss very quickly.

Lethargy
This is a symptom often overlooked. If your dog is conscious, but unresponsive it could be a sign of a serious or life-threatening illness, such as:
Poisoning, Brucellosis, Rabies, Blastomycosis and many more.

Thick mucous discharge from the anus (unaccompanied by a bowel movement)
This is usually a sure sign of a bowel obstruction, and it is often accompanied by a high fever, lethargy, and an almost “hunched-up” posture. If your dog is exhibiting these signs, emergency veterinary is needed as soon as possible. Bowel obstructions cause hypovolemia and shock and can cause death if left untreated for even a short amount of time.

Vomiting blood (hematemesis)
A scarey sight, and one that could indicate a variety of problems, including a foriegn object in the system, possibily causing puncture wounds, poisoning, ulcers, blood disorders, and even cancer.
