A Watchful Eye: Recognizing Senior Pet Health Problems

Changes in how an older dog or cat moves, eats, drinks, breathes, or behaves can signal pain or disease. Here is what to watch for and when to call a veterinarian.

A change in how an older dog or cat moves, eats, drinks, breathes, or behaves is a reason to contact a veterinarian, not a reason to assume the pet is simply getting old. Most senior pets will slow down to some degree, but a new or worsening change can signal pain or disease. Write down what changed and when it started, then let a veterinarian decide how soon the pet should be examined. One sign calls for faster action: according to the American Animal Hospital Association (AAHA) client guidance, persistent coughing or difficulty breathing, including breathing at rest, warrants immediate veterinary contact.

Start with a dated record of what changed

Caregivers are often the first to notice a shift, but a vague impression (“she seems slower”) is hard for a clinician to act on. A short written log makes the change easier to evaluate. For each change, note:

  • What you saw: for example, a hesitation before jumping onto the couch, or drinking from the bowl more often.
  • When it started and how fast it has progressed: sudden, gradual, or worsening over weeks.
  • How often it happens: every day, only after exercise, or only in the morning.
  • Anything that makes it better or worse: warmth, rest, a particular floor surface, or a meal.

Warning signs by body system

The categories below follow the areas AAHA and Cornell University emphasize for older dogs and cats. A single sign rarely identifies a specific disease, and several of these signs can share the same underlying cause. The point of noticing them is to bring a clear picture to the veterinarian.

Mobility and pain

Watch for difficulty rising or lying down, limping, a changed posture, restlessness, and reluctance to walk, play, jump, or use stairs. Irritability, hiding, avoiding touch, and reduced grooming can also reflect pain. Arthritis can progress over time and affect muscle mass, so a change in how a pet stands or moves deserves a veterinary exam even when the change is gradual.

Oral health

Bad breath, red, swollen, or bleeding gums, visible tartar, damaged teeth, and difficulty eating all point toward the mouth. Dental disease can cause pain and other complications. A pet that becomes reluctant to eat, or that drops food or chews on one side, may be showing oral discomfort rather than a lack of appetite.

Kidney and metabolic concerns

Increased thirst or urination, weight loss, reduced appetite, vomiting, and bad breath can accompany kidney disease. None of these signs is diagnostic on its own. Routine examinations and blood work can detect some problems before obvious signs appear, which is one reason AAHA recommends regular senior visits.

Breathing and heart-related signs

AAHA lists persistent coughing, difficulty breathing (including at rest), fatigue, reluctance to exercise, and a swollen abdomen as cardiopulmonary signs. AAHA advises contacting an AAHA-accredited veterinarian immediately when these appear, and says the pet should receive a full examination. Do not wait to see whether the signs pass.

Behavior and cognition

Disorientation, sleep changes, altered interaction with people or other pets, anxiety, house-soiling, increased or changed vocalization, and shifts in activity can have medical, pain-related, sensory, or cognitive explanations. Cognitive dysfunction is a diagnosis of exclusion: it is considered only after other causes are ruled out, because pain and organ dysfunction can produce very similar behavior. A veterinary assessment should come before assuming a behavior change is age-related.

General chronic-disease signals

Malaise, progressive lethargy, altered appetite or thirst, weight loss over time, a change in mobility, and wounds that do not heal are signals that a veterinarian should evaluate. The pattern and the history matter more than any single observation.

Is my cat sick, or is it just old age?

Cornell University College of Veterinary Medicine poses this question directly in its senior-cat resource, The Special Needs of the Senior Cat (last updated December 2016). Its answer is a principle worth keeping in mind: “Age in and of itself is not a disease.”

Cats often hide illness, so a serious problem may not look obvious until it is advanced. Cat caregivers should be alert to changes in litter-box use, grooming, jumping, appetite, vocalization, and social behavior. Cornell notes that these changes may reflect pain, mobility limits, or diseases such as kidney disease, diabetes, or hyperthyroidism. A cat that has trouble reaching its food bowl or stepping into the litter box may not show obvious lameness at all. Cornell advises contacting a veterinarian about any alteration in an older cat’s behavior or physical condition.

How common is joint disease in cats?

Two AAHA figures help explain why feline mobility changes deserve attention. They measure different things, and neither should be applied to a single cat as a personal risk estimate.

Figure Source and date What it means
More than 60% of cats have osteoarthritis in at least one joint, even without crepitus (grinding felt or heard in the joint) AAHA healthy-senior guideline page, published December 13, 2022 A statement about the cat population described in that guidance, not a prediction for an individual cat.
40–92% of cats may show clinical signs associated with degenerative joint disease AAHA 2021 senior-cat guideline A wide range drawn from published studies. It is an estimate, not a prevalence figure to apply to one pet.

New lumps and nonhealing wounds

Do not assume a new lump is harmless because of how it looks. AAHA guidance recommends measuring and evaluating cutaneous masses, and some tumors can resemble benign lumps on examination. Measure the lump with a ruler, photograph it next to a coin for scale, and record the date. Tell the veterinarian whether it has changed in size, shape, or firmness since you first noticed it. A wound that does not heal is listed among general chronic-disease signals and should be examined for the same reason.

What a senior-pet visit involves

AAHA’s client guidance recommends veterinary examinations every six months for pets in the senior range, even when they appear healthy. The thresholds are shown below.

Pet Age threshold in AAHA client guidance Recommended examination interval
Dogs Older than 7 years Every six months
Cats Older than 10 years Every six months

The visit includes more than a physical examination. AAHA’s 2023 Senior Care Guidelines describe a detailed history covering eating and drinking, activity, movement, play, elimination, attitude, grooming, vision, and hearing. The exam includes a dental assessment and a review of nutrition and behavior. Diagnostics are chosen for the individual animal and may include a blood count, chemistry panel, urinalysis, thyroid testing, or blood pressure measurement. The guidelines describe medical workups once or twice a year, with tests tailored to the findings and the patient.

Home video helps the veterinary team judge mobility over time. A short recording of the pet walking, rising from rest, and climbing stairs or jumping gives the clinician something to compare against at later visits.

Preparing for the appointment

  1. Bring the dated change log described above, with any photographs or measurements of lumps.
  2. Include the video of the pet walking, rising, and using stairs or jumping, if you have one.
  3. List all food, treats, supplements, and medications, including how often each is given.
  4. Note changes in water intake, urination, litter-box visits, and stool, even if they seem minor.
  5. Write down your main concern in one sentence so you can raise it early in the visit.

Home adjustments that support access

AAHA includes ramps and stairs among possible home adaptations for pets with compromised mobility. Other practical categories described by AAHA and Cornell are low-entry litter boxes for cats that have trouble stepping over a high edge, and non-slip rugs or traction mats for slippery floors. These changes can make daily life safer and more comfortable while a pet’s condition is evaluated.

These adjustments manage the consequences of a problem. They do not treat the cause of a new gait change, stiffness, or pain, and they do not replace a veterinary evaluation. This article does not compare specific brands or products, and no product quality or pricing is established here.

  • Ramps or stairs: useful for getting onto beds, couches, or into vehicles, but a dog that struggles to climb them still needs an examination.
  • Low-entry litter boxes: helpful for a cat that is avoiding the box or eliminating outside it, though the change in habit itself should be reported.
  • Non-slip footing: reduces slipping on hard floors, which is especially relevant for pets with weak hind limbs or arthritic joints.

Veterinary rehabilitation is another option that AAHA discusses for chronic musculoskeletal disease. Whether it is appropriate depends on the diagnosis, so it should be raised with a veterinarian rather than started on the basis of a home observation.
