Free senior dog calculators and checklists

Check your older dog's age in human years, healthy weight, daily water and sleeping breathing rate, and run quick checklists for bladder infections, leaking urine, weight, dementia and pain. A quality-of-life scale helps with the hardest decision. Each tool takes a minute or two, cites veterinary sources and tells you when to call your vet.

Calculators

• Dog age in human years: Human-age chart, life stage and when your dog becomes a senior, by size.
• Weight and calorie calculator: Normal weight by breed and age, ideal weight, daily calories and a safe weight-loss pace.
• Water intake calculator: How much your senior dog should drink a day, and when it is too much.
• Sleeping breathing rate counter: Tap along while your dog sleeps to get breaths per minute and see if it is in the usual range.

Symptom checklists

• Bladder infection (UTI) symptoms: Straining, frequent peeing, blood or smell: what fits a UTI and when it is an emergency.
• Leaking urine? Incontinence check: Sort leaking from infection, thirst, memory or mobility problems, with next steps.
• Is my dog overweight? Body check: Three quick hands-on checks to estimate the body condition score.
• Dog dementia (CCD) checklist: Confusion, night pacing, accidents and memory changes in older dogs.
• Arthritis and pain checklist: Everyday signs that an older dog is sore, and what helps at home.

End-of-life care

• Quality of life scale: is it time?: Score 7 areas of daily life, track good and bad days, and know when to talk to your vet about euthanasia.

Printables

• Printable weekly health tracker: Log weight, appetite, water, sleep and accidents for your vet. No sign-up.

Call your vet the same day if your dog

• Strains to pee but little or nothing comes out
• Breathing is fast or hard at rest, or the gums look pale
• Stops eating for more than a day, or vomits repeatedly
• An eye is red, painful or suddenly cloudy

Frequently asked questions

Which senior dog calculators are free on SILVERPAW?

All of them: dog age in human years, weight and calories, daily water intake and sleeping breathing rate, plus checklists for UTI symptoms, urinary incontinence, body weight, dementia, arthritis pain and quality of life. No sign-up or email is needed.

Can these checklists diagnose my dog?

No. They help you notice and describe changes, and they point out signs that need a vet the same day. Only a veterinary exam and tests can diagnose a problem.

How often should a senior dog see the vet?

The AVMA recommends that senior pets see a veterinarian twice a year or more, so problems can be found early.
