Dog Dosage Calculator
The Dog Dosage Calculator estimates medication doses for common veterinary drugs based on your dog's body weight in kilograms or pounds. It covers standard dosing ranges for antibiotics, anti-inflammatories, antiparasitic medications, and antihistamines used in canine care. Always confirm any calculated dose with your veterinarian before administering medication, as individual health conditions and concurrent medications can affect the correct dose.
Dog BMI Calculator
The Dog BMI Calculator estimates body condition and weight status for dogs using the dog body condition score (BCS) system developed by veterinary nutritionists. It takes your dog's weight and body measurements to produce a BCS on a 9-point scale, where 4 to 5 indicates ideal condition. Scores below 3 suggest underweight status and scores above 6 indicate overweight risk, both of which affect joint health and lifespan.
Dog Water Intake Calculator
The Dog Water Intake Calculator estimates your dog's daily water requirement in millilitres and cups based on body weight and activity level. Dogs need approximately 50 to 60 ml of water per kilogram of body weight per day under normal resting conditions, and this increases significantly during heat, exercise, or illness. Use it to set a daily intake target and identify when your dog may be at risk of dehydration.

Why a 20-Minute Walk Fails a High-Energy Breed
The most frequent mistake I come across is owners applying a toy-breed exercise plan to a high-energy herding or working dog, often because they live in an apartment or have limited time. A 20-minute daily walk covers roughly 17 percent of what a Border Collie requires, and the result is predictable: destructive behaviour, obsessive patterning, and anxiety. If the calculated target genuinely cannot be met with leash walks, structured mental stimulation through training sessions, scent work, and puzzle feeders can meaningfully supplement physical exercise. This gap turns up most often in urban households with working breed dogs before anyone looks into the mismatch between the dog's daily needs and the routine actually being provided. The ASPCA's guide to common dog behavior issues documents the specific patterns, including destructive chewing and obsessive pacing, that most reliably indicate a dog's exercise needs are not being met.
What the Dog Exercise Calculator Actually Does
This tool estimates the daily physical activity requirement for your dog based on breed group, age, and size class. Dog owners, trainers, and veterinary professionals use it to work out structured exercise plans, identify whether current activity levels are meeting a dog's needs, and adjust routines during rehabilitation or seasonal changes. According to the American Veterinary Medical Association, regular physical activity is one of the most important preventive health measures available, reducing the risk of obesity, joint degeneration, and behavioural problems. Breed group encodes generations of selection for a specific working role, making it the most reliable predictor of a dog's daily energy output needs, which age and size then modify.
How Breed Group Determines Exercise Needs
| Breed Group | Daily Exercise (minutes) | Preferred Activity Types |
|---|---|---|
| Herding (Border Collie, GSD, Aussie) | 90 to 120+ | Off-lead running, agility, training |
| Working (Husky, Malamute, Boxer) | 60 to 120 | Hiking, sledding, swimming |
| Sporting (Labrador, Spaniel, Retriever) | 60 to 90 | Fetch, swimming, field work |
| Hound (Beagle, Greyhound, Bloodhound) | 45 to 60 | Scent work, off-lead in secure area |
| Toy (Chihuahua, Pomeranian, Pug) | 20 to 30 | Short walks, indoor play |
The American Kennel Club's seven breed groups each developed for a specific working function that directly corresponds to energy level. The Herding, Working, and Sporting groups represent the highest exercise demands. That said, within-group variation exists: a Greyhound is a sprint athlete needing short high-intensity bursts rather than sustained aerobic exercise, while a Basset Hound in the same Hound group has far lower demand, consistent with American Kennel Club exercise guidance.
Puppy and Senior Exercise: Different Rules Apply
Puppies have developing musculoskeletal systems, and over-exercise before growth plates close can cause permanent joint damage. The standard guideline is 5 minutes of exercise per month of age, twice daily, avoiding high-impact activities until at least 12 months for most breeds and 18 months for large and giant breeds. Senior dogs benefit from maintained daily movement even as physical capacity declines; reducing frequency rather than eliminating exercise preserves muscle mass and mobility. Swimming is the best exercise for seniors with arthritis, providing conditioning without load-bearing joint stress. Our dog food calculator adjusts daily caloric targets by life stage and activity level to keep intake and output in balance.
Accuracy and Limitations
The calculator returns a recommended daily target based on population averages for each breed group and size class. Individual variation within any breed group can be substantial, and a dog's current fitness, health conditions, and lifestyle should adjust the target up or down. Our dog BMI calculator provides a body condition assessment to help gauge whether current exercise and feeding levels are keeping weight healthy. The calculator does not account for environmental conditions such as heat and humidity, which can significantly limit safe exercise duration in brachycephalic breeds and thick-coated northern breeds; at temperatures above 25°C, reduce intensity and duration and ensure water access throughout. Dogs recovering from surgery or diagnosed with cardiac or respiratory conditions need exercise plans from a veterinary rehabilitation specialist rather than population averages, as the Small Door Veterinary guide to exercise across life stages sets out.

How I built a daily exercise plan after the vet flagged our dog as underactive
At a check-up in April 2026, our vet noted that our 4-year-old border terrier mix was gaining weight and seemed underactive. She asked how much exercise the dog was getting per day. My honest answer was "two short walks, maybe 20 minutes total." The vet recommended significantly more. I used this calculator to work out a realistic daily target based on breed, age, and current weight.
The calculator returned a recommendation of 45 to 60 minutes of moderate activity per day for her age and breed mix. According to the American Veterinary Medical Association's pet exercise guidance, terrier breeds have high baseline activity needs compared to many companion breeds. I restructured the walks into one 30-minute morning session and one 20-minute evening walk, plus a daily 10-minute off-lead session. Over 6 weeks, she lost 900 g and her BCS improved from 6 to 5. The calculator gave me a specific target rather than a vague instruction to "walk more."
