Most Common Causes of Death in Dogs

A healthy dog lives up to 10 – 13 years in human years and is known to have a shorter life span. A pet is more than “just a dog” or “just a cat.” It’s a treasured member of the family who enriches our lives with friendship, amusement, and delight. A pet can give your day structure, keep you engaged with others and active, help you deal with life’s obstacles and challenges, and even give you a feeling of meaning or purpose. So, it’s common to experience overwhelming grief and loss after the death of a beloved pet. Loss and sorrow frequently feel overpowering and can bring on many distressing and challenging feelings, and that’s okay. We are mourning for a loved one, whether human or animal, which is a good experience.

Having prior knowledge of the common causes of death in dogs might help you save your dogs in the future. Of course, you will never know when it will happen, nor will you be able to bring them back alive if they have really left you for good. But at least you’ll know what to avoid or what to do when your dogs catch diseases from parasites like ticks or fleas. Please continue reading to have the knowledge and change anything you practice with your fur babies while they are still young.

Lyme Disease

Dogs with Lyme Disease from ticks might go years without showing any signs. However, your pet may experience significant health issues due to Lyme disease. Pain, appetite loss, and despair are examples of difficult-to-identify symptoms. The Actijoy Health and Activity Dog Tracker will notify dog owners of any changes in feeding or drinking habits, as well as any decreased activity brought on by depression or pain. Early Lyme Disease detection is essential for dogs who spend a lot of time outside.

A black-legged tick can carry the bacteria Borrelia burgdorferi, which can cause Lyme disease in dogs. When sick, dogs may develop a temperature and one or more joint lameness. Additionally, they could appear passive, and their lymph nodes might enlarge.

Kidney Disease

Chronic renal failure results from persistent inflammation of any kidney component (glomerulus, tubule, interstitium). As a result, pinpointing the exact cause of chronic renal failure might be challenging. Polydipsia-polyuria, weight loss, poor body condition, nonregenerative anemia, and an ammonia-like odor on the animal’s breath are the hallmarks of standard clinical presentation.

The kidneys are tiny and atypical upon necropsy. Ulcerative glossitis and stomatitis, gastric ulcers, mineralization of the stomach wall, lung, kidney, or intercostal muscles, and parathyroid lesions are typical uremia-associated lesions.

Renal disease develops when a dog’s kidneys can no longer adequately filter waste from the blood or maintain appropriate hydration. Significantly increased water intake is a clear marker of renal illness in dogs, a simple sign to ignore. The Actijoy solution alerts the owner via a smartphone app when a dog deviates from its normal behavior. This serves as the pet owner’s first warning that something is wrong.


Another study indicated that being overweight was linked to a lower lifespan in the 12 dog breeds examined in an article published by the Journal of Veterinary Internal Medicine in 2018. Dog obesity reduces life span by 2.5 years.

The alarming statistic that more than 55% of domestic pets in America are obese is surprising. Aside from risk factors for diabetes, heart disease, renal, and liver problems, obesity is a significant cause of illness and mortality in canines. Using the Actijoy Health and Activity Dog Tracker, pet owners may manage their dogs’ weight by monitoring the animal’s calorie intake and energy usage.

Canine Parvoviral Infection

Canine parvoviral enteritis, commonly caused by canine parvovirus 2, is another disease that takes away a dog’s life easier. Canine parvovirus 1, sometimes known as the “Minute virus of canines,” is a nonpathogenic virus that seldom causes interstitial pneumonia, diarrhea, or myocarditis in young puppies.

Depression, anorexia, nausea, vomiting, diarrhea, and intestinal bleeding are some traditional clinical manifestations. Certain canines may have a moderate or even subclinical illness. GI symptoms are typically first seen 24 to 48 hours after infection, and early bouts of diarrhea frequently lack blood. The primary cause of intestinal bleeding is progressive intestinal crypt necrosis. A secondary bacterial problem causes septic shock and a high temperature. Necrotizing myocarditis can infect puppies while still in the womb or before they are eight weeks old.
