The 7 Most Overlooked Signs of Aging in Senior Dogs

by Addiction Pet Foods on February 11, 2025

Aging is a natural part of life, and as dogs grow older, they undergo physical and behavioral changes. While some signs of aging—like gray fur and slower movement—are easy to spot, others can be subtle and often go unnoticed. Recognizing these overlooked signs of aging in senior dogs can help you provide better care and improve their quality of life. 

1. Increased Anxiety or Restlessness 

Senior dogs may become more anxious or easily startled, especially in unfamiliar situations. This could be due to cognitive decline, reduced vision or hearing, or even discomfort from joint pain. If your dog suddenly develops separation anxiety or starts pacing at night, it may be a sign that they need extra comfort and reassurance. 

What You Can Do: 

  • Maintain a consistent routine to reduce stress. 

  • Use calming supplements or pheromone diffusers. 

  • Provide a quiet, comfortable space for relaxation. 

2. Sudden Changes in Bathroom Habits 

Older dogs may start having accidents indoors even if they were previously house-trained. This could be due to weakened bladder control, kidney disease, diabetes, or even cognitive dysfunction syndrome (similar to dementia in humans). 

What You Can Do: 

  • Increase the frequency of potty breaks. 

  • Ensure easy access to the outdoors, especially at night. 

  • Consult your vet if accidents become frequent, as it may indicate a medical issue. 

3. Loss of Interest in Favorite Activities 

A senior dog that once loved playing fetch or going on long walks may suddenly seem disinterested. While this could be a normal part of aging, it might also indicate pain from arthritis, fatigue, or underlying health issues. 

What You Can Do: 

  • Offer gentler activities like short walks or puzzle toys. 

  • Monitor your dog for signs of pain, such as limping or stiffness. 

  • Provide orthopedic bedding to ease joint pressure. 

4. Bad Breath or Drooling More Than Usual 

Dental disease is common in senior dogs, yet many pet parents overlook it until it becomes severe. Bad breath, excessive drooling, or difficulty eating can indicate gum disease, tooth decay, or infections that can affect overall health. 

What You Can Do: 

  • Brush your dog's teeth regularly with pet-safe toothpaste. 

  • Schedule professional dental cleanings. 

  • Offer dental chews or kibble designed for oral health. 

5. Changes in Sleeping Patterns 

Senior dogs often sleep more, but if you notice excessive daytime drowsiness or nighttime restlessness, it could be a sign of aging-related changes, pain, or cognitive dysfunction. 

What You Can Do: 

  • Ensure your dog has a comfortable, quiet sleeping area. 

  • Keep a consistent bedtime routine to promote better rest. 

  • If restlessness persists, consult your vet about possible treatments. 

6. Sudden Weight Gain or Loss 

Unexpected weight changes in senior dogs can signal underlying health problems such as thyroid disease, diabetes, or digestive issues. Even if they are eating the same amount, their metabolism may slow down, or they may have trouble absorbing nutrients properly. 

What You Can Do: 

  • Monitor your dog's weight regularly. 

  • Adjust their diet to include easily digestible, high-quality proteins. 

  • Visit your vet for bloodwork if weight fluctuations continue. 

7. Difficulty Navigating Familiar Spaces 

If your dog starts bumping into furniture, hesitating before jumping on the couch, or struggling with stairs, they may be experiencing vision loss or joint stiffness. These gradual changes are easy to overlook until they significantly impact mobility. 

What You Can Do: 

  • Keep furniture in consistent locations to help dogs with vision loss. 

  • Use pet ramps for easier access to elevated areas. 

  • Provide joint-supporting nutrition to maintain mobility.
