Arthritis, Kidney Disease and Wellness Exams for Aging Dogs and Cats

Growing Old in the Mountains — Mountain Vista Veterinary Services, Eureka, Montana

October in the Tobacco Valley is one of those months that reminds you why you live in Montana. The western larches, our only deciduous conifer, turn the mountainsides to molten gold against the dark green of the firs and pines. The first hard frosts silver the valley floor, the air smells of leaf litter and wood smoke, and the world feels like it is pausing before winter.

It is also a good time to look closely at an older companion. If you share your home with an aging dog or cat, senior pet care matters most right now, before the cold settles in and makes every stiff joint harder. Here is what we watch for, what we recommend, and how you can help your pet enjoy their senior years with comfort and dignity.

When Is a Dog or Cat “Senior”?

The answer depends on species and size. Cats are generally considered senior at around ten to twelve, though many live well into their late teens and even twenties. Dogs reach that milestone earlier, and size matters enormously. A Great Dane or Saint Bernard may be senior at five or six, while a small terrier mix may not get there until eight or nine. Large and giant breeds have shorter life expectancies and age faster than their smaller counterparts.

Knowing where your pet falls on that scale helps us tailor their care. It is also why we recommend a change in routine once your pet becomes a senior.

Why Senior Pets Need Exams Every Six Months

We recommend moving from yearly to biannual wellness exams, every six months, when your pet enters their senior years. A great deal can change in an older body in six months, and catching problems early is the most important thing we can do to extend both the length and the quality of your pet’s life.

If you are not sure how often your pet should be seen at any age, our guide to preventive care in Northwest Montana explains how regular exams protect pets at every age.

Senior Pet Bloodwork: What We Test and Why

We encourage every owner of a senior pet to see baseline bloodwork as an investment in early detection, not an expense. A comprehensive panel includes:

  • a complete blood count
  • serum chemistry
  • urinalysis
  • thyroid evaluation

Together these give us a snapshot of how the major organ systems are working. They let us detect kidney disease before clinical signs appear, spot liver changes, catch diabetes early, and monitor thyroid function. Thyroid monitoring is especially important in older cats, who are prone to hyperthyroidism. Once we have baseline values from a healthy period, we can track trends and step in before a slowly worsening number becomes a crisis. Unexplained weight loss in an older pet is another reason to call us. Intestinal parasites picked up outdoors are one cause worth ruling out, as we explain in intestinal parasites your pet picks up in the wild.

Arthritis in Senior Dogs and Cats

Osteoarthritis is one of the most common conditions in senior pets, and in our climate it deserves special attention. The cartilage cushioning the joints breaks down over time, causing pain, stiffness and reduced mobility. Cold weather and shifts in barometric pressure, both plentiful in the Tobacco Valley from October through April, tend to make it worse.

Signs of arthritis in dogs

  • Reluctance to jump into the truck
  • Stiffness after resting
  • A noticeable limp
  • Difficulty with stairs

Signs of arthritis in cats are often much subtler

  • No longer jumping onto favorite high spots
  • Grooming less, leading to a dull or matted coat
  • Becoming less playful

Both dogs and cats are stoic and rarely vocalize pain the way we expect. Learning to read the quieter signs, such as changes in posture, gait, activity and behavior, is an essential skill for any senior pet owner.

Managing Arthritis Pain: Supplements, Medication and Home Changes

We have more tools than ever to manage chronic pain in senior animals:

  • Joint supplements containing glucosamine, chondroitin and omega-3 fatty acids can support joint health.
  • Weight management is critical. Every extra pound stresses compromised joints, and reaching an ideal body condition is one of the most impactful things an owner can do.
  • Anti-inflammatory medication made specifically for dogs, and more recently for cats, gives significant relief when used under veterinary supervision.
  • Adjunctive therapies such as gabapentin, amantadine and Adequan injections can be layered into a pain protocol for pets who need more support.
  • Changes at home make a real difference: ramps in place of stairs, orthopedic or heated beds, non-slip mats on hard floors, and raised food and water bowls.

Kidney Disease in Older Cats

Chronic kidney disease is the leading cause of illness and death in older cats, and it develops so gradually that many owners miss the early signs. Increased thirst and urination are usually the first clues, and they are easy to overlook in a cat who uses a litter box. Weight loss, poor appetite, vomiting and a rough coat follow as the disease progresses.

Cats diagnosed early can often be managed for months or years with diet changes, fluid therapy, and medications that support the kidneys and control nausea and high blood pressure. If your cat is drinking more than usual, call us.

Cognitive Dysfunction in Senior Dogs

Canine cognitive dysfunction syndrome, the animal equivalent of dementia, is increasingly recognized in senior patients. Signs include:

  • disorientation
  • pacing and restlessness at night
  • house soiling in a previously reliable dog
  • less interaction with the family
  • aimless wandering

There is no cure, but diet, supplements, environmental enrichment and medication can slow progression and improve quality of life. Some of these changes overlap with anxiety, so see our guide to how to treat anxiety in dogs and cats as well.

Smoke, Heat and Other Seasonal Risks

Older pets cope less well with extremes. Senior animals with heart or breathing problems are especially vulnerable when wildfire smoke settles into the valley, so keep them indoors with filtered air and watch for coughing or labored breathing. Our guide on how to protect your pets when wildfire season starts early covers what to do.

Caring for the Heart as Well as the Body

We would be remiss not to acknowledge the emotional side of caring for a senior pet. Watching a companion who once bounded through the snow along the Tobacco River trails slow down and change is one of the harder parts of pet ownership.

Our team at Mountain Vista Veterinary Services is here for more than medical management. We are here for the honest conversations about quality of life, the treatment options that make sense for your pet and your family, and the gentle guidance that helps you through this chapter with love and clarity.

Schedule a Senior Wellness Exam in Eureka

If your senior dog or cat has not been seen in the last six months, we invite you to schedule a senior wellness exam at our clinic in Eureka, Montana. The golden larches remind us that change is beautiful, even when it is bittersweet, and that caring well for our aging companions is among the most meaningful things we do.

Frequently Asked Questions

What age is a dog considered senior? It depends on size. Giant breeds like Great Danes may be senior at five or six, while small dogs may not reach that point until eight or nine.

How often should a senior cat see the vet? We recommend an exam every six months once a cat reaches about ten to twelve years, with bloodwork to catch kidney disease and thyroid problems early.

How can I tell if my old dog or cat is in pain? Dogs may limp, stiffen after rest, or balk at stairs and jumping into the truck. Cats often show pain more quietly, by skipping high perches, grooming less, or playing less. Tell us about any change like this, since pain can be treated.

Is slowing down just normal aging? Some change is normal, but stiffness, increased thirst, weight loss, nighttime pacing and house soiling are signs of treatable conditions, not “just old age.”
