Discover the 15 most common health problems that can affect our canine companions, from allergies to hypothyroidism. This guide offers a snapshot of each condition’s signs and symptoms to help you keep your furry friend healthy and happy.
Allergies

Dogs with allergies may show itching, red skin, hair loss, and paw licking due to reactions to foods, pollen, or fleas. Indications include excessive scratching, sneezing, and gastrointestinal problems. Early signs are chronic ear infections and frequent skin infections.
Obesity

Obesity shortens dogs’ lifespans and can lead to diabetes, heart disease, and joint issues. Signs are weight gain, breathing difficulties, and less play. Check for a missing waistline and indiscernible ribs. Obesity also worsens respiratory problems and activity reluctance.
Dental Disease

Dental disease in dogs causes bad breath, plaque, and painful chewing. It results in appetite and weight loss and can also lead to tooth loss and significant organ infections. Monitoring for excessive drooling or avoidance of hard foods and regular dental check-ups are essential.
Ear Infections

Ear infections are frequent in dogs, especially those with floppy ears. Symptoms are head shaking, scratching the affected ear, redness, and a foul odor. Yeast or bacteria often cause these infections. Tilting the head often may also be a sign.
Parasites

Canines afflicted by fleas, ticks, and worms exhibit scratching and skin irritations and risk severe conditions like Lyme disease. Anemia and death can occur; hence, preventive treatments and vigilance for markers like a dull coat or weight loss become critical.
Skin Infections

Dogs can develop skin infections from bacteria, fungi, or allergies, leading to itchiness, redness, hair loss, and severe conditions like hot spots and dermatitis. Persistent infections might indicate allergies or hormonal issues. Watch for excessive licking, chewing, scabs, or scaling.
Arthritis

In older dogs, arthritis leads to joint pain, stiffness, and a lower quality of life, marked by limping, trouble standing, and avoiding stairs. Pain may cause irritability and behavioral changes, with visible muscle loss around the limbs and spine.
Diabetes

Diabetes manifests in pups through extreme thirst, frequent urination, weight loss, and hunger due to abnormal glucose use. It necessitates ongoing management because, without treatment, it may cause blindness and cataracts. Sweet breath indicates ketoacidosis, a critical condition that requires immediate care.
Epilepsy

Epilepsy in dogs leads to seizures, marked by shaking, drooling, and loss of consciousness, manageable with medication. After seizures, dogs might seem disoriented or blind. To manage seizures effectively, you should observe seizure patterns and follow up with your veterinarian on a regular basis.
Cancer

It is more common in older dogs to develop lumps, swelling, sores, and weight loss due to cancer. Symptoms like unexplained lameness or behavioral shifts and aggression may indicate discomfort or pain from cancer, which stresses the importance of prompt veterinary consultation.
Heart Disease

Heart disease in dogs presents symptoms such as fatigue, coughing, breathing difficulties, and decreased ability to exercise. Advanced stages of the disease are indicated by fainting or collapsing due to poor circulation and a swollen abdomen caused by fluid accumulation.
Kidney Disease

In older dogs, kidney disease causes waste accumulation, triggering vomiting, weight loss, excessive thirst, and urination. Chemical-scented lousy breath and mouth ulcers may also signal the condition. Prompt identification via blood and urine analysis is vital for effective management.
Gastrointestinal Issues

Dogs’ gastrointestinal problems vary in severity and may lead to vomiting, diarrhea, and appetite loss, often due to infections, parasites, or diet concerns. Serious indicators include blood in vomit or stool and swift weight loss. Early detection, like abrupt food aversion, helps avert grave conditions.
Hip Dysplasia

Hip dysplasia, prevalent in large dog breeds, leads to hip joint deformity and arthritis, shown by limping, trouble standing, and aversion to movement. The condition is often characterized by a distinctive “bunny hopping” gait. Timely detection via frequent vet visits is critical for managing this genetic ailment.
Hypothyroidism

Hypothyroidism, due to low thyroid hormone production, causes weight gain, fatigue, hair loss, and skin conditions and can be managed with ongoing medication. It may also cause ear infections, slow heart rate, cold sensitivity, mood changes, and even depression or aggression in dogs.
