Have you noticed your dog skip meals or pant hard after a short walk? A quick check with a thermometer can show a fever over 102.5°F, which may harm your dog’s organs if you wait too long.
This list shows eight vet-approved signs, from weight loss and blood in urine to trouble breathing. Keep reading.
Key Takeaways
- Dogs that skip meals for over 24 hours or run a fever above 102.5°F need a vet check. Pain from gum disease or an upset stomach often hides behind a wagging tail.
- Vomiting or diarrhea that lasts more than one day can cause a dog to lose 5% of its body weight in fluids. Finding blood in vomit or stool calls for an emergency vet visit.
- Healthy dogs breathe 10 to 30 times per minute at rest. If you count chest rises for 30 seconds and double it, a steady rate above 30 breaths per minute means urgent care (Dr. Katie Krebs, University of Pennsylvania).
- Rapid weight loss may point to diabetes or cancer, and sudden weight gain can signal Cushing’s syndrome or hypothyroidism. Weigh your dog weekly to catch trends early.
- Limping or stiff joints may hide pain from osteoarthritis, which affects almost 39% of dogs aged 9 months to 4 years (Dr. Courtney Pierce). New aggression or confusion can mark brain issues or thyroid problems (Dr. Krista Williams).
What causes a loss of appetite in dogs?
Dental problems such as gingivitis and gum disease cause pain when a dog chews, so many pups skip meals. A loss of appetite in food-motivated breeds like Labradors raises alarm, especially if a dog avoids dog food for over 24 hours.
Vets advise a checkup at that point. Pain from periodontal disease hides behind a wagging tail; an owner might see no limp or cough.
Sudden disinterest can point to gum disease or an upset stomach. Interest in food that returns quickly eases worries. Experts sometimes recommend a bland diet or probiotics for dogs to coax a weak eater.
A thorough exam rules out hidden issues.
When should you worry about vomiting or diarrhea in your dog?
A single bout of regurgitation might not ring alarm bells. Many dogs gag after grass or hairballs. But persistent vomiting in dogs or diarrhea in dogs that lasts over 24 hours needs a phone call to your clinic.
Dogs can lose 5% of body weight in a day from fluid loss. That risk jumps in puppies or senior dogs. Gastroenteritis or parasites can cause severe GI infection. Blood in vomit or stool demands emergency care.
You might spot red streaks or dark coffee ground material. Veterinarians use fecal tests and blood tests to check for worms or organ issues.
Intermittent bouts of diarrhea can point to food intolerance or a bad batch of kibble. Pancreatitis may hit breeds like Miniature Schnauzers or Dachshunds. A vet might suggest an ultrasound to check for an intestinal blockage or tumor.
IV fluids can restore lost electrolytes fast. Probiotics for dogs help rebuild gut flora after antibiotic use or UTI treatment. Track weight and watch for lethargy. Quick action can save dog health and prevent kidney or liver damage.
What does lethargy or extreme fatigue indicate in dogs?
Owners spot unusual tiredness that lasts for several hours. They notice lack of response to toys or walks. Poisoning or toxins may cause this. Pain from joint inflammation can wear out a dog fast.
Heart disease in dogs, including congestive heart failure, may weaken a pet. Neurological disorders can cut energy levels. Infections or metabolic disorders like diabetes in dogs can drain strength.
Brief tiredness after a run is normal, and dogs bounce back. Ongoing fatigue demands a vet check. A vet can check for heartworm disease, urinary tract infection, or Addison’s disease.
They can run tests for heart disease in dogs, blood sugar, or neurological exams. Early treatment for serious issues boosts recovery and dog health.
How to recognize difficulty breathing or wheezing in dogs?
Dogs may face difficulty breathing when they pant hard, lift chests rapidly, flare nostrils, and snort oddly. Healthy dogs rest at ten to thirty breaths per minute. Dr. Katie Krebs at the University of Pennsylvania tells us to count chest rises over thirty seconds, then double the number.
Any steady rate above thirty breaths at rest demands urgent care.
Wheezing often points to airway blockage from allergic reactions, kennel cough, pneumonia in dogs, congestive heart failure, or choking. Collapse may follow heartbeat irregularity, internal gut bleeding, or sudden brain injury, says Dr.
Carly Fox of Schwarzman Animal Medical Center. Watch gum color for pale or blue hues that reveal low oxygen. Grab a stethoscope or pulse oximeter if you own one, and race to the emergency vet.
What can cause unexplained weight changes in dogs?
Unexplained weight changes can signal trouble. Rapid weight loss may point to metabolic disorders or diabetes in dogs. Sudden weight gain can flag Cushing’s syndrome or hypothyroidism in dogs.
Some cancers in dogs hide behind weight loss. Infections and blood disorders can also cause shifts.
Scale your dog once a week to catch trends early. Jot down numbers in a log or app. Spotting changes fast gives you power to act. Watch for extra thirst or dull coat. Seek a vet’s advice if weight loss or gain shows up.
What does blood in urine, stool, or vomit mean for your dog?
Blood in urine or stool or vomit signals an urgent vet visit. Bright red blood may come from a bladder problem or anal tear. Dark, tarry stool can point to a bleeding ulcer, gastrointestinal problem, or cancer.
Infections, minor injuries, poisoning, and bladder stones all can cause bleeding.
Watch for pain during urination or more vomiting. Toxins, bladder infection, or cancer in dogs may hide behind bloody urine. A vet uses urinalysis, fecal exam, sonogram, or endoscope to trace the source.
Quick action boosts treatment success.
How to identify limping or signs of pain in dogs?
Puppies and seniors may drag a paw after a walk. Owners should watch for head bobbing or toe touching. Excessive whining or stiff joints can signal pain. Vets use X-ray and a stethoscope to find injury or Lyme disease.
X-rays reveal joint wear in almost 39 percent of dogs aged 9 months to 4 years. Experts estimate 40 percent of dogs suffer pain from osteoarthritis. Dr. Courtney Pierce calls this a hidden threat.
Dogs with osteosarcoma often favor one leg after exercise.
What do sudden behavioral changes in dogs signify?
Sudden shifts in a dog’s mood, like new aggression, confusion, or pulling away, may hint at pain or a brain issue. A ten-year-old Golden stops chasing balls. It no longer jumps up to greet you at the door.
This pattern could link to neurological disorders or cognitive decline. Low thyroid levels, infections, or cancer may also spark odd behavior. Dr. Krista Williams at VCA Animal Hospitals warns that dogs might guard their food or toys when in pain.
That guarding can become a real risk around kids. You must note these changes and call a specialist who reads canine body language.
Persistent scratching, odd restlessness, or sudden fear could point to allergies, parasites, or infections. An ear infection might make a pup shake its head all day. Cystitis can cause your friend to circle before squatting.
Aggressive acts might hide anxiety, stress, or pure boredom. A trainer or behavior coach can guide you past resource guarding. Blood work and urinalysis reveal diabetes mellitus or a bladder issue.
Radiographs or an MRI can catch heart disease or a back problem. Act fast if you see these signs, since silent symptoms often join behavioral changes in dogs.
When is coughing in dogs a serious concern?
Occasional coughs in dogs often fade after a day or two. Persistent coughing in dogs that lasts more than two weeks can signal heart disease in dogs or lung infection. Veterinarians use a stethoscope to listen and may order a chest x-ray.
Results often show kennel cough, pneumonia in dogs, or other serious lung conditions.
Cough that comes with lethargy or appetite loss needs a vet visit. Don’t let the cough set up camp in your pup’s throat. If your dog sounds hoarse or spits up phlegm, act fast.
An exam at a veterinary clinic keeps pet health on track. Early treatment aids dog wellness and can save a life.
When should you be concerned about a swollen or closed eye in your dog?
Swollen or shut lids often point to eye abrasion, high pressure, or stuck dust particles in the eye. Sharp pain makes a dog paw at its face, or hide. Watch for discharge or cloudiness, these signs need fast vet care.
Dr. Rebecca MacMillan at TrustedHousesitters warns that delays may lead to vision loss when glaucoma in dogs goes unchecked.
Veterinarians test eyes with a fluorescein stain and a tonometer. They may use an ophthalmoscope to check the retina. This work links to pet health and eye checkups. Acting fast averts serious damage and cuts down long term risk.
What does fever or elevated body temperature mean in dogs?
Raised temperature spells trouble. A dog reading 103°F feels hot. Thermometer device helps you find the exact number with a digital probe. Normal range for dogs sits between 100.5°F and 102.5°F.
Call a vet for any result that tops 102.5°F. Long fevers can damage organs like heart or kidneys.
Giving human meds, like aspirin or Tylenol, can cause liver or kidney failure without vet OK. Infections, immune reactions, or heatstroke often trigger a hot body. Track your pet health and dog wellness by checking temperature twice daily if fever lasts.
Contact the clinic if heat shows no drop after 24 hours.
What are the signs of trouble or pain during urination in dogs?
Dogs that strain or whine while peeing need a vet check. Bright red streaks or brownish tinge in the urine signal blood in the urine. A foul smell or cloudy look can point to a bladder infection.
Housespots made by tiny dribbles reveal urinary incontinence or stress. Constant licking of the rear can hide pain down low. Left unchecked, upper urinary tract infections can harm the kidneys.
A simple urinalysis or an ultrasound can spot a renal disease, endocrine issues, or high blood sugar condition fast.
What causes pacing, restlessness, or gagging in dogs?
Restless pacing, repeated gagging, or retching can signal bloat, also called gastric dilatation volvulus. This condition ranks as the second leading cause of death in dogs. It can strike any breed, but deep chested dogs face higher odds.
The stomach twists and fills with air, creating compressive pressure. They pace as if they forgot their chew toy upstairs. They pant, drool and retch.
A veterinarian may use radiography or ultrasound to confirm a twist. You can cut risk by feeding small portions, using a slow feed bowl and holding exercise for an hour after meals.
Takeaways
Keep your pup in top dog health by watching these eight signs. Grab a thermometer and stethoscope at home. Note any coughs, gut issues, weight shifts, or odd bathroom runs. Seek help fast if your dog drags its paws, pants hard, or shows blood in stool.
Quick visits save lives, and peace of mind costs less than regret. Your vet can spot a bladder infection or heart disease early. Pay close mind, stay alert, and enjoy many happy walks ahead.
