Do dogs get heavier as they get older? A Comprehensive Guide

The most recent statistics from the Association for Pet Obesity Prevention estimated that 55.8 percent of U.S. dogs were classified as overweight or obese. While the terms are sometimes used interchangeably, there is a definitive difference between being overweight and obese.

Remember that before starting any exercise or diet program a dog should have a complete physical performed by a licensed veterinarian to rule out heart, endocrine, and joint issues. Responsible dog owners observe their dog’s daily behavior and know how much exercise their dog can safely handle and enjoy on a day-to-day basis.

An article published in the Journal of Veterinary Internal Medicine reported on a study of more than 50,000 dogs consisting of 12 breeds. Researchers found that an overweight body condition was associated with a shorter life span in all breeds studied, but the magnitude of the effect varied — being least for large‐breed dogs at 5 months shorter lifespan and greatest for dogs of the smallest breed at greater than 2 years shorter lifespan.

“Most veterinary nutritionists recommend a consistent diet in order to ensure a balanced meal,” says Dr. Alvarez. “The most important nutrient for senior dogs is high-quality protein, due to a higher need for protein levels.” It’s also important to have consistency from everyone in the household. If the kids are sneaking snacks to your dog from the table, they’re not really doing him any favors.

Other Causes of Weight Gain in Older Dogs

Some other conditions that could cause Fido to gain weight include…

  • Stress – like us, anxious senior dogs sometimes ‘stress eat’
  • Medication – older dogs are often on medication, and some can cause weight gain
  • Water retention – this can be caused by illness, or by medications
  • Breed type – some breeds are more prone to gaining weight than others
  • Medications which can cause Fido to put on weight, or retain water, include anti-inflammatories, corticosteroids and anti-depressants.

    Some dog breeds which are more prone to being overweight as they age include Labrador Retrievers, Basset Hounds, Beagles, Rottweilers, Spaniels, St. Bernards, Bulldogs and Dachshunds.

    BUT, pretty much any dog can get too fat given the right (or wrong) circumstances, diet, or health problems!

    Other Causes of Weight Gain in Dogs

    Genetics plays a part in your dog’s tendency to gain weight, too. Some breeds are just more prone to putting on weight than others.

    The breeds more inclined to be obese include American cocker spaniels, basset hounds, beagles, Cairn terriers, Cavalier King Charles spaniels, dachshunds, Labrador retrievers, Norwegian elkhounds, rough collies, and Shetland sheepdogs.

    Fluid buildup due to heart disease or liver disease can also trigger weight gain, as can tumors (for example, a large abdominal tumor can make a dog look fat)

    Dogs which have been spayed or castrated are also more likely to be obese, probably because neutering affects energy expenditure and metabolism.
