Most healthy adult dogs need between 30 and 120 minutes of activity a day, split into at least two sessions. Breed group, age and body shape move that number far more than weight does. A Pug and a Border Collie of the same size sit at opposite ends of the range.
Toy and companion breeds such as Pugs, Shih Tzus and Cavalier King Charles Spaniels do well on 30 to 45 minutes a day. Medium working breeds like Beagles, Cocker Spaniels and Australian Shepherds need 60 to 90 minutes. Herding and sled breeds, including Border Collies, Huskies and Vizslas, need 90 minutes to 2 hours plus a job to do. Setters, Retrievers and Greyhounds sit in between at 45 to 60 minutes across two walks.
Flat-faced dogs overheat faster because their airways are narrow, so 20 to 30 minutes twice a day in the cool hours suits them better than one long run. Split every target into two or three walks: two shorter outings do more for behaviour than one long one, especially for a dog that spends the day alone. A dog left for 9 hours needs the longer half of its allowance after you get home.
A common guideline for puppies is 5 minutes of formal exercise per month of age, twice a day. A 4-month-old puppy gets about 20 minutes per session. Growth plates close between 12 and 18 months, later in large breeds, and damage done before they close shows up as arthritis years later. Keep large-breed puppies off stairs and slippery floors until the plates have closed.
Free play in the yard is self-limiting and does not count the same way, but repetitive jumping, long runs on hard pavement and jogging with a puppy all do. Let the puppy set the pace, keep sessions short, and stop when it flops down rather than pushing for one more lap. The five-minute figure is a starting point, since free play, sniffing and training all spend energy too.
Sniffing and problem solving tire a dog in a way distance does not. A 10-minute walk with free sniffing can leave a dog as settled as a 30-minute march. Scent games, puzzle feeders and five minutes of obedience training spend the same energy budget as a burst of running. Five minutes of scent work with a handful of treats can match a kilometre of road walking for effort.
Destructive chewing, pacing and barking at the window usually mean the dog has energy left over. Adding one sniff-heavy walk or a frozen stuffed toy often fixes the behaviour faster than adding another kilometre, and it is easier on the joints. A stuffed, frozen food toy takes 30 to 45 minutes to empty and buys back that time in a settled dog.
Senior dogs keep moving, just less and more often. Two or three 15-minute walks hold muscle and joint range better than one 45-minute effort. Swimming and flat, soft ground suit arthritic dogs. Ask a vet before starting any new programme if your dog has a heart, joint or breathing condition. Warm water is gentler on stiff joints than cold, and short frequent sessions build muscle without triggering a flare-up.
Watch for a dog that lags behind on a route it used to lead, or that needs a longer recovery the next day. Both are reasons to shorten the walk and book a check rather than push through. Lameness that lasts past the following morning is never tiredness. Gentle daily exercise also slows the muscle loss that starts in most dogs around age 8.
Too much shows up as limping that lasts beyond the next morning, heavy panting that continues 10 minutes after the walk ends, reluctance at the door, or sore paws. Too little shows up as chewed furniture, digging, humping and a dog that cannot settle in the evening. Judge over a week: one stiff day after a long hike is normal, three in a row is a signal to pull back.
Hot pavement burns pads at surface temperatures above roughly 50 degrees Celsius, which is common on a sunny afternoon. Press the back of your hand to the ground for 5 seconds: if you cannot hold it there, walk on grass or wait until the evening.
