Is It an Emergency? Veterinary Symptoms You Should Never Ignore

When a dog or cat suddenly becomes unwell, it is not always easy to know whether the problem can wait for a regular veterinary appointment. Pets cannot tell us how severe their pain is, and some life-threatening conditions initially cause symptoms that may appear mild. North Vancouver Vet
As a general rule, sudden changes involving your pet’s breathing, consciousness, circulation, ability to urinate or level of pain should be treated seriously. The veterinary team at Lonsdale Place Veterinary Clinic wants pet owners to recognize the warning signs that require immediate attention.
The following symptoms should never be ignored. North Vancouver Vet
1. Difficulty Breathing
Breathing difficulty is always an emergency. A pet that is not receiving enough oxygen can deteriorate rapidly, even when the underlying problem began only recently.
Warning signs may include:
Open-mouth breathing, especially in cats
Gasping or struggling to inhale
Rapid breathing while resting
Noticeable movement of the abdomen with each breath
Stretching the neck forward to breathe
Loud, raspy or unusual breathing sounds
Blue, grey, very pale or purple gums
Collapse, weakness or extreme distress
North Vancouver Vet
Breathing problems can have many causes, including heart disease, asthma, pneumonia, allergic reactions, airway obstruction, chest trauma or fluid around the lungs.
Keep your pet calm and minimize handling. Do not place anything inside the mouth unless you can clearly see a loose object that can be removed safely. Proceed to the closest veterinary emergency hospital immediately. Difficulty breathing is among the conditions requiring immediate veterinary treatment.

2. Repeated or Severe Vomiting
A single episode of vomiting in an otherwise bright, comfortable adult pet may not always be an emergency. However, repeated vomiting can quickly cause dehydration and may be a symptom of a more serious condition.
Seek prompt veterinary attention when vomiting:
Occurs repeatedly within a short period
Contains blood or dark material resembling coffee grounds
Is accompanied by severe diarrhea
Occurs in a puppy, kitten, elderly pet or medically vulnerable animal
Prevents your pet from keeping water down
Is associated with pain, weakness, trembling or collapse
Occurs after possible ingestion of a foreign object or toxin
Is accompanied by a swollen abdomen or repeated unsuccessful retching
North Vancouver Vet
Foreign objects, intestinal obstruction, pancreatitis, kidney disease, poisoning and severe gastrointestinal disease can all cause vomiting. Diagnostic imaging may be needed to identify potentially life-threatening causes such as an ingested object.
Do not give human anti-nausea medication unless specifically instructed by a veterinarian.

3. Collapse or Sudden Extreme Weakness
Collapse means that a pet suddenly falls, cannot remain standing or becomes unresponsive. Even when a pet appears to recover within a few moments, the episode may indicate a significant problem.
Possible causes include:
Internal bleeding
Heart disease or an abnormal heart rhythm
Low blood sugar
Heatstroke
Severe allergic reaction
Respiratory disease
Neurological disease
Shock
Toxin exposure
North Vancouver Vet
Check whether your pet is conscious and breathing, but avoid unnecessary movement. If trauma may have occurred, support the body carefully while transporting your pet. Collapse, loss of consciousness and signs of shock require urgent assessment.

4. Suspected Toxin Exposure
Do not wait for symptoms to develop after a possible poisoning. Some substances cause delayed organ damage, and treatment may be most effective before visible illness begins.
Common household hazards include:
Chocolate
Xylitol-containing gum, candy or baked goods
Human medications
Cannabis products
Rodenticides
Antifreeze
Grapes and raisins
Lilies and other toxic plants
Cleaning chemicals
Certain mushrooms
Insecticides and garden products
North Vancouver Vet
Remove your pet from the substance and collect the packaging, ingredient list or a photograph of the suspected toxin. Contact a veterinarian or animal poison-control service promptly. Do not induce vomiting unless a veterinary professional specifically instructs you to do so, as vomiting can make some exposures more dangerous.
The ASPCA Animal Poison Control Center is available 24 hours a day at 888-426-4435, although a consultation fee may apply.

5. Inability to Urinate
A pet that repeatedly attempts to urinate but produces little or no urine may have a urinary obstruction. This is especially dangerous in male cats, although urinary emergencies can affect other animals as well.
Signs may include:
Frequent trips outside or to the litter box
Straining without producing urine
Producing only a few drops
Crying or vocalizing while attempting to urinate
Blood in the urine
Licking the urinary opening
Vomiting, hiding, weakness or loss of appetite
North Vancouver Vet
A complete urinary blockage prevents waste products from leaving the body and can cause dangerous electrolyte abnormalities. Blocked urine flow requires immediate veterinary treatment.
Do not assume that your pet is constipated. Urinary straining can look similar, particularly in cats.

6. A Swollen or Painful Abdomen
A suddenly enlarged abdomen can be caused by gas, internal bleeding, fluid accumulation, organ enlargement or gastric dilatation-volvulus, commonly called GDV or bloat.
Warning signs include:
A firm, enlarged or rapidly swelling abdomen
Repeated attempts to vomit without producing anything
Excessive drooling
Pacing or inability to settle
Looking repeatedly at the abdomen
Rapid breathing
Pale gums
Weakness or collapse
North Vancouver Vet
GDV occurs when the stomach becomes enlarged with gas and may twist, interfering with blood supply. It is most common in large, deep-chested dogs, but any dog with a rapidly swollen, painful abdomen needs emergency evaluation. Typical signs include abdominal swelling, restlessness, repeated dry retching and excessive drooling.
Do not offer food, water or medication while travelling to the emergency hospital.
7. Seizures
A seizure may involve falling over, stiffening, paddling of the legs, jaw movements, drooling, urination or loss of awareness. Some seizures are less obvious and may look like staring, facial twitching or sudden abnormal behaviour.
During a seizure:
Move objects away to prevent injury.
Keep your pet away from stairs and water.
Dim the lights and reduce surrounding noise.
Time the seizure.
Record a video when it is safe to do so.
Do not place your hands near your pet’s mouth.
Pets do not swallow their tongues during seizures, and attempting to hold the tongue can result in a serious bite.
Proceed to an emergency hospital when a seizure lasts several minutes, multiple seizures occur close together, your pet does not recover normally, toxin exposure is possible, or this is your pet’s first seizure. Ongoing seizures require immediate treatment.

8. Significant Trauma
Pets should be assessed after major trauma even when they initially appear normal. Adrenaline can temporarily mask pain, and internal bleeding or lung injuries may not be immediately visible.
Examples include:
Being struck by a vehicle
Falling from a significant height
Being attacked by another animal
A deep bite or puncture wound
Severe bleeding
An eye injury
A suspected fracture
A large or deep wound
Trauma followed by pale gums, breathing changes or weakness
North Vancouver Vet
Use a towel, blanket or flat board to support your pet during transportation when a spinal injury or fracture is possible. Apply gentle, direct pressure to active bleeding using a clean cloth, but do not repeatedly remove the cloth to check the wound.

Trust Your Instincts
You know your pet’s normal behaviour better than anyone. A sudden, dramatic or unexplained change deserves attention, even when it does not fit neatly into one of the categories above.
Contact Lonsdale Place Veterinary Clinic during our regular hours when you are concerned about your pet’s health. If your pet is experiencing breathing difficulty, collapse, ongoing seizures, inability to urinate, suspected poisoning, major trauma or another rapidly worsening condition, proceed directly to the nearest veterinary emergency hospital.
