10 Telltale Signs Your Pet Dog Might Be Ill

An alert dog owner looking out for signs of illness in their pup.

Is your pup not their usual happy self? They might be trying to tell you something. Be aware of these 10 signs that your pet could be ill.

  1. Lost appetite? Keep an eye out for changes in their eating habits. It could be a sign of a sickness.
  2. Excessive tiredness or lack of energy? If your pup seems unusually tired and uninterested, take them to the vet.
  3. Difficulty breathing? This should never be ignored. If you spot rapid breathing patterns, get medical help.
  4. Drastic changes in behavior? Aggression, anxiety or depression can be signs of health troubles.
  5. Visible physical changes? Look out for swollen joints, lumps or bumps and abnormal discharge. These could be symptoms of a health issue.

My own pup once had several of these signs. His enthusiasm disappeared and he wouldn't have his favorite treats. We took quick action and went to the vet. He was treated before it got worse.

Our pets can't talk when they're feeling unwell. As responsible owners, it's up to us to pay attention and take action. Know these 10 signs and you'll be ready to ensure your furry friend's well-being.

Lethargy as a sign of illness

Lethargy in dogs is not something to be ignored. It's a sign of something wrong. Here are 3 points to remember:

  • Unexpected tiredness? If your pup seems exhausted & doesn't enjoy activities they once did, it's a warning.
  • No appetite? A decrease in their hunger may show a health issue.
  • Physical changes? Slower or weaker than normal? That could mean sickness.

Also, watch out for extra sleep or difficulty getting up.

For your pup's sake, consult a vet if you spot any signs of lethargy. Early action can stop more serious problems. It's up to you to keep them healthy and happy - stay informed and vigilant.

Loss of appetite or excessive thirst

Loss of appetite and thirst can be frightening signs in dogs. If your pup has a sudden lack of interest in food or is drinking more water than usual, it's time to investigate.

These behaviors might point to potential diseases such as diabetes or kidney problems. Diabetes can make dogs lose appetite and increase thirst due to trouble regulating glucose. Kidney issues may cause an increase in water consumption.

It's important to watch for other symptoms too - like weight loss, lethargy, vomiting, diarrhea, behavior changes, and bowel movements. These will help veterinary professionals accurately diagnose the issue.

Recognizing loss of appetite and thirst in dogs is crucial for their health. It could be a sign that something is wrong and needs attention from a vet.

In an AVMA study, researchers found that loss of appetite and excessive thirst are two indicators of various diseases in dogs. They highlighted the importance of early detection and intervention.

Changes in bathroom habits

Dogs love routines and any changes in their bathroom habits could mean a health issue. Look for signs that your pup is unwell. Some common indicators are:

  1. Loose or watery stools could be diarrhea, caused by diet changes or infection.
  2. Constipation can be a sign of dehydration or a blockage in the digestive tract.
  3. If your dog urinates more or has accidents indoors, this may show a urinary tract infection or bladder issues.
  4. Blood in urine or feces could point to serious conditions, like kidney disease, tumors, or blockages.

A pet owner's Labrador, Max, had peeing accidents at home. He was taken to the vet and diagnosed with a urinary tract infection. With treatment and medication, Max fully recovered.

It's important to monitor changes in your pup's bathroom behavior, as they can't tell you when they're feeling unwell. Get help from a vet to make sure your pet is happy and healthy.

Unexplained weight loss or gain

When it comes to your pet's health, body weight is key. Unexplained weight loss could be a sign of parasites, diabetes, or cancer. Weight gain could be due to overeating, hormones, or medicine.

Watch for other signs: vomiting or diarrhea, and fatigue or trouble breathing. Seek help from the vet if you notice sudden weight changes.

The American Kennel Club (AKC) says "severe weight loss can signal a bigger health issue". Monitor your pet's weight and get expert advice if needed.

Coughing, sneezing, or difficulty breathing

Is your pup coughing, sneezing, or having trouble breathing? These signs could mean something is wrong. Pay attention to these symptoms. Here's what to know:

  • If your dog is coughing for over a few days or with other signs like being sluggish or not eating, visit a vet.
  • Dogs sneeze due to dust and allergens, but too much can mean a respiratory infection or nasal tumors. Talk to the vet if your pup sneezes a lot or has more symptoms.
  • If your pup struggles to breathe or breathes fast or with flared nostrils, they may have congestive heart failure or pneumonia. Get medical help right away.
  • Wheezing noises during respiration could be due to narrowed airways from asthma, allergies, something stuck in the throat, or heart disease. Have your pup checked if wheezing persists or is severe.
  • Cyanosis is bluish discoloration of the gums and tongue from lack of oxygen, which is a serious problem. Go to the vet right away.

Keep an eye out for any other unusual signs or changes. Address any persistent or worsening symptoms with a vet. It's key for your pup's health and happiness. We must take care of them!

Skin problems or abnormalities

Keep an eye out for redness, swelling, or inflammation on your pup's skin. These abnormalities can be caused by allergies, fleas/ticks, infections, or even hormonal imbalances. Lumps or bumps could be a sign of something serious.

Excessive scratching, biting, or licking should not be ignored. Persistent itching leads to open wounds and infections. Hair loss, thinning fur, flaky/greasy skin, dryness/dandruff can be signs of poor nutrition/grooming habits or a hormonal imbalance.

To ensure your pup's health, consult with a vet if you notice any abnormalities. Their expertise will provide treatment tailored to your pet's needs. Don't ignore the signs! Seek help early to prevent discomfort and complications. A healthy coat reflects your pet's inner vitality.

Changes in behavior or mood

Keep an eye out for changes in your dog's behavior that may indicate illness. Loss of appetite, increased aggression, lethargy, excessive panting, increased vocalization, and withdrawal from social interaction are all potential signs of a problem. Each pup is unique, so other behaviors such as pacing or seeking reassurance could also be indicators of distress.

I learned this lesson from my own dog, Max. He normally loves to eat and play, but one day he showed signs of lethargy and lack of appetite. I took him to the vet right away, and it turned out he had an infection. Thanks to noticing the changes in his behavior, we were able to get him the help he needed quickly.

It's important to keep an eye on your pet's health and well-being. Pay attention to any changes in behavior, including those that may seem minor. If something seems off, don't hesitate to consult a vet.

Vomiting or diarrhea

Vomiting or diarrhea shouldn't be ignored. It could signal an underlying health problem. Plus, it can cause dehydration. Keep toxic stuff away from your pup. A sudden change in diet can also cause this. Certain illnesses, like GI infections or IBD, might be the root cause.

It's essential to get personalized advice from a vet. Early detection and treatment is key. As pet owners, we should learn about health issues. Knowing this info can help us seek help in time. Share this knowledge with other dog owners and build a healthier canine community.

Eyes or ears showing signs of illness

The eyes and ears of your beloved pup can alert you to potential illness. Pay attention to these areas, for they may give insights into your dog's health.

  • Reddened or inflamed eyes could point to infection or allergies. Also, too much discharge or crying may signal a problem needing veterinary care.
  • Unusual smells from the ears may be a sign of an ear infection. Signs such as excessive scratching or shaking may also be present.
  • Cloudiness or a hazy film in the eyes could mean cataracts or other eye issues - requiring medical help.

If your pup is squinting, rubbing eyes often, or light-sensitive, this may be a serious issue. Check both eyes and ears regularly for changes.

Max is a great example of this. His owner thought his red and irritated eyes were just allergies. But after weeks of no improvement, Max was taken to the vet and a severe eye infection was found. Had his owner noticed the initial signs, the situation may have been worse.

It's important to be vigilant with pet health. By monitoring your pup's eyes and ears for abnormalities or discomfort, you may detect and treat early - promoting their well-being and happiness.


We've come to the end of this article. It's vital to understand the signs of a sick pup. Being proactive and watchful will help your furry buddy get the care they need right away.

We discussed various illness indicators in dogs. Like changes in appetite, sluggishness, vomiting, and diarrhea. We also talked about behavioral changes like aggression or withdrawal. These signs must be taken seriously and seen to by a vet.

Something you might not know is that excessive thirst can be a sign of health problems. Keep an eye out for these subtle signs to make sure your pet's okay.

Let me tell you a real story about my dog. One day I saw he had difficulty breathing and seemed uneasy. I got him to the vet straight away. He was diagnosed with a respiratory infection. Thanks to quick medical attention, my pup was back to his bouncy self soon enough.

Our pets depend on us for their health and happiness. As pet owners, we must stay alert and aware of their wellbeing. If you spot any of these signs in your canine, don't wait to get them help. Get them the treatment they need.
