Dogs may not speak our language, but they do tell us when something’s wrong—if we know what to look for. As pet parents, one of the most loving things we can do is learn the warning signs of common health issues and take simple steps to prevent them.

From itchy skin to more serious conditions like heartworm, many health problems in dogs can be avoided or minimized with a little proactive care. Whether you’re a new dog owner or a seasoned pet pro, this guide will help you keep your furry friend happy, healthy, and tail-wagging.

1. Dental Disease

The Problem: Dental disease is incredibly common—affecting over 80% of dogs by the age of three. It starts with plaque and tartar buildup and can lead to gum infections, tooth loss, and even heart or kidney issues if bacteria enter the bloodstream.How to Prevent It:
  • Brush your dog’s teeth regularly: Use a toothbrush and toothpaste made specifically for dogs. Aim for brushing at least 2-3 times per week. 
  • Provide dental chews or toys: Choose products with the Veterinary Oral Health Council (VOHC) seal of approval to ensure they are effective. 
  • Schedule professional cleanings: Your vet can perform deep cleanings and check for early signs of dental disease. 
Warning Signs: Bad breath, red or bleeding gums, difficulty chewing, or a loss of appetite.

2. Obesity

The Problem: Obesity isn’t just about extra weight—it puts strain on joints, increases the risk of diabetes, and shortens your dog’s life span.How to Prevent It:
  • Stick to portioned meals: Consult your vet or use a feeding chart based on your dog’s weight, breed, and activity level. 
  • Limit treats: Treats should make up no more than 10% of your dog’s daily calories. Opt for healthy options like carrot sticks or apple slices. 
  • Ensure daily exercise: Daily walks, play sessions, and interactive toys can keep your dog active and trim. 
Warning Signs: Visible weight gain, difficulty moving, shortness of breath after light activity.

3. Ear Infections

The Problem: Dogs with floppy ears (like Labs, Goldens, and Cocker Spaniels) are especially prone to ear infections due to moisture and lack of airflow.How to Prevent It:
  • Clean ears regularly: Use a vet-approved ear cleaner and gently wipe out wax or debris. Avoid using cotton swabs deep in the ear canal. 
  • Dry ears after water exposure: After baths or swimming, use a towel or cotton ball to gently dry the inside of your dog’s ears. 
  • Monitor for signs of irritation: Regular checks can help you catch infections early before they worsen. 
Warning Signs: Head shaking, scratching at ears, odor, discharge, or redness inside the ear.

4. Fleas and Ticks

The Problem: Fleas and ticks aren’t just gross—they can cause itching, allergic reactions, and transmit serious illnesses like Lyme disease or tapeworms.How to Prevent It:
  • Use monthly preventatives: Speak with your vet about topical or oral flea/tick control options. 
  • Keep your yard clean: Mow the grass regularly and remove brush or debris where pests may hide. 
  • Check your dog after outdoor play: Use a flea comb and inspect high-risk areas like ears, armpits, and between toes. 
Warning Signs: Excessive scratching, hair loss, red bumps, visible parasites.

5. Parvovirus (Parvo)

The Problem: Parvo is a highly contagious and potentially fatal virus that affects puppies and unvaccinated dogs. It attacks the digestive system, causing severe vomiting, diarrhea, and dehydration.How to Prevent It:
  • Vaccinate your puppy: Stick to the vaccination schedule provided by your vet. 
  • Avoid high-risk areas: Until your puppy is fully vaccinated, steer clear of dog parks, pet stores, or anywhere unknown dogs gather. 
  • Disinfect properly: If exposed, clean with vet-approved disinfectants, as parvo is resistant to many household cleaners. 
Warning Signs: Vomiting, bloody diarrhea, lethargy, loss of appetite, fever.

6. Skin Allergies (Canine Atopic Dermatitis)

The Problem: Just like people, dogs can have allergies—from pollen and dust to food and flea bites. This often shows up as chronic itching, redness, and hot spots.How to Prevent It:
  • Regular baths with medicated shampoo: Helps reduce allergens on your dog’s coat and soothe irritated skin. 
  • Manage diet and environment: Work with your vet to identify food or environmental triggers and eliminate them when possible. 
  • Use flea control consistently: Flea bites can trigger severe allergic reactions in sensitive dogs. 
Warning Signs: Constant licking or scratching, red or inflamed skin, hair loss, ear infections.

    7. Heartworm Disease

    The Problem: Transmitted by mosquitoes, heartworm is a serious condition where worms live in the heart, lungs, and blood vessels. Left untreated, it can cause organ damage and be fatal.How to Prevent It:
    • Use monthly preventatives: These medications protect against heartworms and often cover intestinal parasites too. 
    • Minimize mosquito exposure: Use screens, remove standing water, and avoid outdoor play during peak mosquito hours. 
    • Annual testing: Even with preventatives, yearly tests ensure early detection and peace of mind. 
    Warning Signs: Coughing, fatigue, weight loss, labored breathing—though in early stages, symptoms may not appear at all.

    BONUS: One Overlooked but Preventable Problem—Yard Hygiene

    Dog poop isn’t just an eyesore—it can contribute to parasites, bacteria, and pest problems that affect your dog’s health. In summer months, especially in Georgia’s heat, waste breaks down faster and attracts more flies, spreading germs through your yard and into your home and increasing summer health risks.
