Do you always recognize when your dog needs veterinary care? This guide will help you spot warning signs that require more than sympathy and may mean you should call your veterinarian right away.
#1: Red Flag Signs
Some symptoms demand immediate attention. While a few are obvious—like visible bleeding—others can be subtle. If you notice any of the following, call your vet or emergency clinic without delay. It’s better to be cautious than to miss a serious problem.
- Active Bleeding: Blood dripping or spurting from a wound.
- Non-productive Retching: Repeated attempts to vomit without bringing anything up can indicate bloat or a twisted stomach (gastric dilation and volvulus), a life-threatening emergency.
- Straining: Any strong straining, especially when trying to urinate, may signal a urinary blockage and requires urgent care.
- Collapse or Sudden Weakness: Inability to stand, severe weakness, or labored breathing needs immediate assessment.
- Trauma: After a road accident, fall, or dogfight, always get a veterinary check—even if your dog seems to recover—because internal injuries may be delayed.
#2: Increased Thirst or Loss of Appetite
Noticeable increases in drinking or peeing, or a sudden drop in appetite, are important signals. In multi-dog households, watch for the pet that frequently heads outside or has accidents indoors. Increased thirst and urination can stem from urinary infections, diabetes, or kidney disease. These signs are rarely immediate emergencies but should be checked promptly. If possible, bring a urine sample to the appointment—simple tests often provide valuable information. Likewise, if a normally voracious dog suddenly refuses food, that change is meaningful and warrants attention.
#3: Vomiting
Vomiting can result from simple stomach upset but can also indicate infections, pancreatitis, liver or kidney disease, or uterine infection in intact females. Occasional vomiting in an otherwise bright dog can be monitored, but certain patterns require prompt veterinary advice:
- Sickness and Diarrhea Together: Combined fluid loss raises the risk of dehydration.
- Blood in Vomit: May suggest severe inflammation or gastric ulcers.
- Lethargy: If your dog seems unusually weak or listless.
- Fever: Elevated body temperature alongside vomiting is concerning.
- Repeated Vomiting: Ongoing vomiting over several hours or repeated episodes in a day.
- Unable to Keep Water Down: Puts the dog at risk of dehydration and kidney strain.
#4: Diarrhea
Diarrhea follows similar rules to vomiting. A single loose stool may not be urgent, but prolonged or severe diarrhea is. Call your vet if you see:
- Large volumes of watery stool
- Bloody diarrhea (red, dark, or coffee-ground appearance)
- Repeated episodes or ongoing diarrhea
- A dog that seems unwell, weak, or dehydrated
#5: Blood Loss or Pale Gums
Blood in the urine or feces should be taken seriously. Even small, chronic blood loss can lead to anemia. Anemic dogs may appear tired and show pale gums. Check your dog’s gums by lifting the lip: healthy gums are a blush pink, while pale pink, gray, or white gums suggest anemia and require urgent veterinary evaluation to determine the cause and begin treatment.
#6: Altered Breathing
Normal panting after exercise or in hot weather is expected, but unusual breathing at rest is a warning sign. Pay attention to:
- Rapid, Shallow Breathing: More than about 30 breaths per minute at rest is significant and should be evaluated.
- Exaggerated Abdominal Effort: Using the belly to draw in air—especially at rest—can indicate respiratory distress.
- Coughing or Wheezing: These may result from infections, bronchitis, heart disease, airway obstruction, or tumors.
If breathing changes are hard to describe, a short video of your dog breathing at rest can be very helpful for your veterinarian.
#7: Racing Heart
An unusually fast or irregular heartbeat is an important early sign of potential heart disease. Early detection and treatment can improve quality of life and extend survival. While monitoring heart rate exactly at home can be difficult, devices that track heart rate and activity can assist owners and veterinarians in spotting concerning changes.
#8: Discharges and Foul Odors
Unusual discharges or bad smells often point to localized infections or dental problems. Common sources include:
- Ears: Discharge, odor, or excessive scratching may indicate an ear infection.
- Vulva: Vaginal discharge in an intact female can suggest a uterine infection.
- Mouth: Persistent bad breath can signal dental disease or oral infection.
- Skin: Sticky, smelly, or inflamed skin warrants veterinary attention.
#9: Unexplained Weight Loss or Gain
Unexpected changes in weight or body shape—without diet changes, pregnancy, or deliberate weight management—can indicate underlying disease. Whether your dog is losing weight despite a normal appetite or gaining weight rapidly, have them assessed to determine the cause.
#10: Pain
Pain in dogs can be subtle. Look for behavioral and physical clues that may mean your pet is uncomfortable:
- Whining, unusual vocalization, or changes in temperament
- Restlessness at night or difficulty settling
- Grumpiness, snapping, or uncharacteristic aggression
- Limping, stiffness, or reluctance to move
- Loss of appetite or reluctance to reach the food or water bowl
- Anxious facial expression, drawn-back ears, lip licking, or increased panting
- Reduced interest in play, walks, or other normal activities
If you suspect pain, don’t delay—timely assessment and pain relief can prevent worsening and improve recovery.
If in Doubt…
Trust your instincts. Changes from your dog’s normal behavior—refusing to greet you, not eating, hiding, or altered elimination—are how your dog communicates that something is wrong. Observe closely: check stool, watch urination, and, if you know how, take a temperature. Use these observations to describe the issue clearly to your veterinarian.
