Impact of Obesity in Dogs

For better or worse, dogs love to follow in their owner’s footsteps.  As of 2018, studies show over 40% of Americans were obese.  Coincidentally, 56% of the nation’s dogs were obese or overweight.  Dogs are considered overweight once their weight reaches 15% above average.  They matriculate into the obesity zone when their weight exceeds 30% above average. 

Osteoarthritis

Also known as Degenerative Joint Disease (DJD), osteoarthritis is what happens when joint cartilage deteriorates, causing inflammation to intensify.  It makes simple tasks like standing up, going upstairs, and jumping onto a bed or couch extremely more difficult.  Cartilage cushion naturally breaks down over time.  However, obesity adds unnecessary stress to the joints with every step your dog takes, expediting the process of osteoarthritis a great deal.  Frequent stress from physical activities like walking, running and playing take a toll on your dog’s joints.  The additional weight makes each movement more stressful and causes the cartilage to break down more easily.  Osteoarthritis is most common in larger breeds like Golden Retrievers, Labrador retrievers, and German Shepherds, but obesity makes any breed vulnerable to the disease.

Diabetes

Diabetes Mellitus is the result of insulin withdrawals in the pancreas, which impact’s the animal’s use of fats, proteins, and sugars.  Some dogs are genetically more susceptible, but obesity is one of the most common causes of the disease.  Obesity causes cells in your pet’s body to reject insulin, causing their overall blood sugar levels to go up.  Warning signs for diabetes include increased thirst and urination, loss of eyesight, and lethargy.  Reach out to your veterinarian right away if your pup has been experiencing these symptoms.

Decreased Life Expectancy

Obesity is known to have a direct negative impact on the longevity of a dog’s life.  A study of Labrador Retrievers concluded that even being slightly overweight can take up to two years off your dog’s life.  Excess fat tissue releases inflammatory hormones and can help contribute to other diseases. Dr. Ernie Ward, the founder of the Association for Pet Obesity Prevention, said on the matter, “I see the consequences, and I wish for those pets that I could roll back the tape to five years ago and say ‘let’s change a few minor things here and there and we could have avoided all of this.’  It’s avoidable, not inevitable.”

“It’s not only that these obese dogs face a shorter life expectancy, but it’s the quality of life they’re leading in the first place.” 
— Dr. Ernie Ward

Financial Trouble

Besides the health risks, having an obese pet can prove to be a costly situation.  Dr. Ward estimates obese animals cost their owners hundreds of millions of dollars (collectively) on a yearly basis.  He also believes that costly vet expenses resulting from obesity would go away with smarter food choices and consistent exercise for our pets.


Without a doubt, obesity has a severely negative impact on the quality of your pet’s life.  Take daily walks, ration food properly, and reach out to your vet if need be.  Be proactive and take the precautions to give your pet the longest, healthiest life possible.
