Hi fellow animal lover,

 

As dogs age, their metabolism slows down, their activity levels change, and keeping a healthy weight becomes more important than ever. Whether your senior pup is packing on extra pounds or losing muscle mass, both can impact their mobility, comfort, and overall well-being.

Why Weight Matters More in Senior Dogs

 

Extra Pounds = Extra Strain – Even a few extra pounds can put more pressure on aging joints, making arthritis and mobility issues worse.


Weight Loss Can Be a Red Flag – Sudden weight loss could be a sign of dental disease, organ issues, or muscle loss due to aging.


Obesity Shortens Lifespan – Overweight dogs are at higher risk for diabetes, heart disease, respiratory issues, and certain cancers.

 

How to Help Your Senior Dog Stay at a Healthy Weight

 

Adjust Their Diet

  • Feed for their age & activity level – Senior dogs need a balanced diet that supports joint health, digestion, and muscle maintenance.

  • Watch portions – Metabolism slows down, so they may need fewer calories than before. Use a measuring cup or kitchen scale to avoid overfeeding. To help prevent your dog from feeling a bit "hangry," add fiber-rich veggies (like green beans) to help them feel full without extra calories.

  • Choose high-quality protein – Lean meats, fish, and eggs help maintain muscle without unnecessary calories.

Adjust Their Exercise

  • Shorter, more frequent walks – Senior dogs may tire faster, but gentle movement keeps joints and muscles strong.

  • Sniffari Walks – Letting them sniff and explore provides mental enrichment while keeping them active.

  • Low-impact activities – Swimming or walking on soft surfaces (grass, dirt) is easier on aging joints.

Muscle Loss in Senior Dogs

 

Losing weight isn’t always a good thing! Muscle loss (sarcopenia) is common in aging dogs and can make them weaker, less stable, and more prone to injuries.

 

How to Prevent Muscle Loss


✔️ Keep them moving – Gentle, regular exercise helps maintain strength.

✔️ High-quality protein diet – Look for foods with real meat and muscle-supporting nutrients like omega-3s and amino acids.

✔️ Joint supplements – Glucosamine, chondroitin, fish oil, or type II denatured collagen can support mobility and keep them active longer.
