Senior dog care (8+ years)

The final years of your dog's life are the most important: the time when they need you most. Good geriatric care adds significant quality of life and can extend a happy life by 1-3 years. This guide covers everything you need to know.

When is my dog a senior?

It depends on the size:

• Small breeds (chihuahua, yorkie): senior at 9-10 years
• Medium breeds (border collie, golden): senior at 7-8 years
• Large breeds (labrador, german shepherd): senior at 6-7 years
• Giant breeds (great dane, saint bernard): senior at 5-6 years

Physical and behavioural changes

Normal changes with age:

• Grey hairs on the muzzle and around the eyes
• Less energy, more naps
• Stiffer movement when getting up
• Reduced hearing and sight
• Reluctance to jump onto the sofa/into the car
• Changes in the sleep cycle

Changes that are NOT normal and require a vet:

• Sudden or ongoing loss of appetite >48h
• Unexplained weight loss
• Excessive thirst + urinating much more
• Repeated vomiting
• Persistent cough or laboured breathing
• New lumps on the skin
• Sudden behavioural changes

Adapted diet

A senior dog's basal metabolism drops by 20-30%. If you keep feeding the same amount, they'll put on weight.

Features of senior dog food:

• High-quality but MODERATE protein (kidney function)
• Less fat to avoid excess weight
• More fibre for intestinal regularity
• Joint supplements: glucosamine, chondroitin, omega-3
• Antioxidants: vitamin E, selenium, vitamin C
• Smaller or softer kibble if they have dental problems

Recommended brands: Hill's Mature Adult, Royal Canin Mature, Acana Senior. If they have a specific kidney problem, the vet can prescribe a therapeutic diet.

Exercise: less quantity, more care

Your senior dog should NOT stop exercising. But adapt it:

• Shorter but more frequent walks (3-4 × 20 min instead of 2 × 45)
• A slower pace, let them set it
• Avoid extremely hot days (greater risk of heatstroke)
• A soft surface is better than concrete (parks, grass)
• NEVER forced runs, high jumps, or running alongside a bicycle
• If they limp or whine, head home and see a vet soon

Osteoarthritis: problem #1

80% of dogs over 8 years old have some degree of osteoarthritis. It's the leading cause of reduced quality of life in older dogs.

Signs:

• Stiffness when getting up (better after 5-10 min of movement)
• Reluctance to jump, climb stairs or get into the car
• A changed posture when sitting
• Intermittent limping
• A change in temperament (growling when touched on sore areas)

Combined management:

• A veterinary behaviourist or orthopaedic vet for diagnosis (X-rays)
• Anti-inflammatories (Carprofen, Meloxicam) as directed by the vet — do NOT self-medicate
• Joint supplements: glucosamine + chondroitin + omega-3
• Weight control: every kilo less = much less pain
• Canine physiotherapy (available in many towns, it transforms quality of life)
• An orthopaedic bed + ramps instead of jumping
• Veterinary acupuncture (yes, it works in many cases)

Cognitive decline (canine dementia)

Cognitive Dysfunction Syndrome (CDS), the canine equivalent of Alzheimer's. Symptoms (acronym DISHA):

• Disorientation · stands still staring at walls, gets lost in the house
• Interaction (social) altered · seeks less affection or becomes more needy
• Sleep-wake cycle altered · sleeps by day, barks at night
• House-training habits · accidents indoors with no medical cause
• Activity altered · more apathetic or more restless

Treatments:

• Selegiline (medication, slows progression)
• Specific diets (Hill's b/d, Purina Bright Mind)
• Supplements: SAMe, omega-3, antioxidants
• Mental enrichment: interactive toys, walks in new places
• Keeping to predictable routines

Kidney and liver health

Chronic kidney failure is very common in older dogs. Early detection is key:

• ANNUAL blood + urine test from 7-8 years of age
• Markers: urea, creatinine, SDMA (more sensitive than creatinine)
• If detected, a specific renal diet + fluid management + medication
• With early detection, dogs can live for years with good quality of life

Teeth and oral health

85% of dogs over 5 years old have periodontal disease. In seniors it gets worse:

• Built-up tartar → gingivitis → periodontitis → tooth loss
• Strong bad breath (it's not "dog smell", it's a sign of disease)
• Pain when chewing → less food → weight loss
• Oral bacteria reach the heart, kidneys, liver → systemic problems

Veterinary dental cleaning under general anaesthetic every 1-2 years. Daily brushing with dog toothpaste (NEVER human toothpaste, it contains toxic xylitol).

Veterinary check-ups

For senior dogs, ideally every 6 months instead of yearly:

• A full physical exam (palpation of lumps, joints, ears, eyes)
• Weighing (sudden changes = alarm)
• A full annual blood + urine test
• Chest + abdomen X-rays every 2 years (early cancer detection)
• Adjusting vaccines + parasite treatments according to mobility
• Dental cleaning when the vet recommends it

Being there at the end of their life

When the time comes, there are hard decisions. Some principles:

• Quality > quantity: days of chronic pain are not a life
• A trusted vet is your ally in understanding the prognosis
• Humane euthanasia: when there's no possible treatment, delaying prolongs suffering, not a happy life
• Home euthanasia: home-visit vets available in many cities, less stress for the dog
• Saying goodbye: offer them their favourite food, their spot, their people. Be with them
• Grief: it is real and profound. Allow yourself to cry. Online support groups and some veterinary practices offer support.

In summary: your senior dog needs adjustments to diet + exercise + more frequent check-ups. Early detection of osteoarthritis, kidney problems and cognitive decline is KEY to maintaining quality of life. These years are the most important, make them count.
