Senior Dog Health: 10 Changes to Watch After Age 7

Published by MaunaPet. Editorial policy and sources.

As dogs age, they transition into their senior years. But when exactly does a dog become a "senior"? This largely depends on their size and breed. Small breeds typically become seniors at 10-12 years, medium breeds at 8-10 years, large breeds at 7-8 years, and giant breeds as early as 5-6 years.

10 Key Changes to Watch For

Monitoring your dog for signs of aging can help catch diseases early and improve their quality of life. Here are 10 major changes to watch after age 7:

1. Cognitive Decline (Canine Cognitive Dysfunction - CCD): Symptoms include disorientation, altered interactions with family members, sleep-wake cycle disruptions, and house soiling.
2. Vision Loss: Cloudy eyes (nuclear sclerosis or cataracts) can affect vision, particularly at night.
3. Hearing Loss: You may notice your dog ignoring commands or sleeping through loud noises.
4. Increased Thirst and Urination: This can be a sign of kidney disease, diabetes, or Cushing's disease.
5. Weight Changes: Unexplained weight loss or gain can indicate underlying health issues such as thyroid disease or cancer.
6. Joint Stiffness: Osteoarthritis is common in older dogs, causing them to slow down on walks, struggle with stairs, or take longer to stand up.
7. Dental Disease: Bad breath, drooling, or difficulty eating may indicate periodontal disease, which can affect internal organs if left untreated.
8. Lumps and Bumps: While many are benign fatty tumors (lipomas), any new lump should be checked by a veterinarian.
9. Incontinence: Urinary incontinence can occur, particularly in spayed females.
10. Behavioral Changes: Increased anxiety, irritability, or reluctance to be touched may be signs of underlying pain or illness.

Veterinary Care for Senior Dogs

Bi-annual veterinary visits are crucial for senior dogs. A senior blood panel can help detect issues like kidney disease, liver dysfunction, or diabetes before symptoms become severe. This proactive approach is the best way to extend your dog's life.

Diet and Exercise Adjustments

Senior dogs typically require diets lower in calories but higher in protein to maintain muscle mass, with added joint supplements like glucosamine and omega-3 fatty acids. Exercise should be modified to be gentle and low-impact, such as swimming or shorter, more frequent walks.

Cognitive enrichment, such as puzzle toys and learning new, simple tricks, can also help keep your senior dog's mind sharp and slow the progression of cognitive decline.
