Spotting the signs of illness in your dog is essential for their health and well-being. Indeed, dogs often tend to hide their pain, which can make it difficult to identify symptoms.
Here, we guide you through the visible and invisible signs of illness in dogs and how to ensure your dog’s good health and well-being!
Visible Signs of Illness in Dogs #
Change in Dog Behavior #
A change in behavior is often the first indicator that a dog is not feeling well. If your dog suddenly becomes more distant, more nervous, or more aggressive, it may be a sign of pain or discomfort. Similarly, a dog that hides or shows a sudden disinterest in their favorite activities might be suffering from something they cannot express otherwise.
💡 Examples of behaviors to watch for:
- Change in social interactions
- Aggressiveness or fearful behavior
- Isolation or withdrawal from the family group
Alteration of General Condition: Fatigue and Lethargy #
Another visible sign of illness in dogs is the onset of excessive fatigue or lethargy. If your dog seems more tired than usual, even after periods of rest, it could signal an infection, a chronic illness, or even a heart problem. A sick dog may lose interest in walks, play, or social interactions, which can indicate illness.
💡 Signs of excessive fatigue:
- Lack of interest in walks
- Refusal to play or interact
- Sleeping longer than usual
Digestive Disorders: Vomiting and Diarrhea #
Digestive disorders, such as vomiting, diarrhea, or loss of appetite, are common signs of illness in dogs. These symptoms can be associated with infections, intestinal parasites, or gastrointestinal diseases. If these symptoms persist for more than 24 hours, it is imperative to consult a veterinarian.
💡 Common digestive symptoms to watch for:
- Frequent vomiting
- Persistent diarrhea
- Refusal to eat or drink
Respiratory Problems in Dogs #
Respiratory disorders such as persistent coughing, excessive panting, or difficulty breathing should be taken seriously. This could be a sign of a lung infection, an allergy, or even a heart problem. Older dogs or those with breeds predisposed to heart problems should be closely monitored.
💡 Signs of respiratory problems:
- Continuous or hacking cough
- Noisy or panting breathing
- Difficulty breathing
Invisible Signs of Illness in Dogs: Monitoring Vital Signs #
Some illnesses do not manifest with immediate visible signs. That’s why it’s essential to monitor your dog’s vital signs, which can indicate health problems.
Your Dog’s Heart and Respiratory Rates #
Heart rate and breathing are crucial indicators of your dog’s overall health. A resting heart rate higher than normal or irregular breathing can signal heart or lung problems.
Vital signs to monitor:
Parameter | Normal resting value | Concerning resting value |
---|---|---|
Heart rate | 60 to 120 beats/min | > 120 beats/min |
Respiratory rate | 10 to 30 breaths/min | > 30 breaths/min |
If a normal heart rate can vary so much, it is mainly due to the size of your dog. The smaller they are, the faster their heart beats, and vice versa for larger dogs.
Dog’s Body Temperature #
A dog’s normal temperature ranges between 100.4°F and 102.2°F. A temperature above 102.2°F or below 100.4°F can indicate an infection, inflammation, or another health problem.
What to Do If in Doubt? #
Of course, if you observe any of these signs in your dog, the first reflex is to contact your veterinary clinic. By describing the symptoms, your specialist can already guide you on whether or not to consult and within what time frame.
It is important to note that the earlier a disease is detected, the easier it is to treat. So do not hesitate to react if the symptoms persist or worsen!
