As pets live longer, veterinary teams are increasingly managing age-related conditions that impact quality of life. Ageing in dogs and cats is accompanied by physiological changes that may not be immediately visible but can significantly affect organ function, mobility, cognition, and overall wellbeing. Early detection and proactive management are essential. 

At NationWide Laboratories, we support veterinary practices with a comprehensive portfolio of diagnostic tools tailored to senior pets. From canine wellness testing and feline wellness testing to advanced senior pet profiles and geriatric profiles, our services are designed to help you identify subtle changes before clinical signs emerge, enabling timely intervention and personalised care.

Senior Dogs 

Ageing dogs often present with complex, overlapping conditions that require a structured diagnostic approach. Our Canine Senior Health Check Plus T4 and Canine Geriatric Profile are designed to support early detection and ongoing monitoring of age-related changes.  

These profiles assess: 

• Liver and kidney status (ALT, ALP, GGT, SDMA, creatinine, urea) 
• Electrolyte balance (sodium, potassium, chloride, Na:K ratio) 
• Metabolic health (glucose, cholesterol) 
• Endocrine status (total T4) 
• Haematology and urinalysis 

Routine canine wellness testing helps establish baselines and track trends over time, allowing you to intervene before clinical signs progress. For breeds at higher risk of cancer, the Nu.Q® Vet Cancer Test offers a non-invasive screening tool that detects nucleosome changes in blood supporting earlier diagnosis and improved outcomes. 

BSAVA PetSavers and NationWide Laboratories launch exclusive partnership for the Ageing Canine Toolkit (ACT) 

Alison Selby, Fundraising Manager for BSAVA PetSavers said: “We are thrilled to be embarking on this partnership with NationWide Laboratories. Working together in partnership, we hope to equip owners with the knowledge and confidence to support their dogs through the ageing process, ultimately improving their quality of life.” 

At NationWide Laboratories we’re proud to partner with BSAVA PetSavers to support the Ageing Canine Toolkit (ACT), developed by the University of Liverpool. This evidence-based resource is designed to help veterinary professionals and pet owners identify early signs of age-related disease and guide meaningful conversations during consultations. 

The Ageing Canine Toolkit (ACT) fits in well with our diagnostic offering, such as canine wellness testing, senior pet profiles, and canine geriatric profiles by helping veterinary teams connect clinical findings with the day-to-day realities of a dog’s behaviour, mobility, and overall wellbeing. It provides a practical framework to support early intervention, strengthen client communication, and enhance the continuity of care for ageing canine patients. 

The Ageing Canine Toolkit (ACT) includes: 

• A traffic light colour-coded checklist for owners 
• Information on common conditions in senior dogs 
• A framework to support proactive, collaborative care 

Senior Cats 

Cats are masters at masking illness, making proactive screening essential in senior care. Our Feline Senior Health Check and Feline Geriatric Profile Plus are designed to uncover early signs of disease through a comprehensive panel that includes: 

• Kidney status (SDMA, urea, creatinine) 
• Liver enzymes (ALT, ALP, GGT) 
• Electrolytes (sodium, potassium, chloride, Na:K ratio) 
• Metabolic markers (glucose, cholesterol) 
• Endocrine screening (total T4) 
• Haematology and urinalysis 

Feline wellness testing is a cornerstone of preventative care, helping you detect subtle shifts in health status before they become clinically significant. With expert interpretation from our veterinary pathologists, you can confidently tailor treatment plans and improve outcomes for your ageing feline patients.
