Pugs
Since they tend to wheeze, don’t run pugs for more than a mile and a half. Three 15-minute walks are more appropriate.

Yorkshire terriers
“Yorkies were bred to chase rats,” explains Chodosh. So despite being tiny, these mop–tops can scurry from a half mile to a mile and a half depending on size, age and personality. They will run around on their own inside, but a 30–minute game of fetch will help tire them out before bedtime.

Dachshunds
Wiener dogs—bred with stumpy legs to drive badgers from holes—are surprisingly solid athletes, but Cohosh doesn’t recommend a running routine longer than one mile (or 20 minutes), since their odd build predisposes them to spinal damage. Take them on at least three 15-minute walks daily.

Poodles
One of the most common breeds in the city, these dogs are consistently smart, yet vary in size: A one–mile run is enough for a toy poodle (20 minutes of vigorous indoor playtime will suit him fine), three to four miles is best for a miniature, and five miles is ideal for a standard, says Okas.

St. Bernards
A brisk two-mile walk is all these massive hounds need. Because they’re prone to heart and joint problems, they really shouldn’t sprint—particularly if they’re less than a year old.

Pomeranians
These beauties love long walks on the street (45 minutes to an hour), but long–distance jaunts aren’t their forte; a dashing game of catch should provide them with sufficient cardio. The same goes for others in the toy category, Havanese, shih tzus and Cavalier King Charles Spaniels among them.

Beagles
“Born with an amazing sense of smell, beagles follow their noses and must always be on a leash,” Okas says. They have great stamina and “can run three miles a day—those from hunting lines even more.” At the very least, they should be taken out on several power walks daily.

Labrador retrievers
“Awesome running partners, Labs will easily trot eight miles or more–and love it all the while,” says Chodosh. Prone to becoming overweight, Labs especially benefit from exercise. However, they won’t let on if they’re hurt, so Chodosh recommends running them no more than four miles at a time. Three 30–minute walks daily will suffice, but some Labs will require six to ten miles to be truly content (up to two and a half hours of walking total). Golden retrievers are equally good running companions, so the same rules apply.

Jack Russell terriers
These pint-size pedigrees are tough. “We put them with the big dogs,” attests Cohosh. “On an average day, we run them 1.5 miles, but they can easily go five to six.”

Greyhounds
Normally laid-back, racing hounds spring for short, fast dashes in a dog run, but “they can tolerate slower jogs for longer stretches, too,” Okas notes. “Three miles a day is ideal.”

Huskies
In the wintertime, you’ll tire out faster than this sled dog, which can clock 12 miles, no problem.

Dalmations
Despite their high energy, these dogs can be “bitchy as hell” when you try to make them your jogging buddy, says Cohosh. They can go two miles easily, but they’d rather do it off the leash. Likewise, border collies have the stamina for pavement pounding, but they’d rather do it in an open field. If you can, take them to the dog run a couple of hours each day.

Weimeraners
This bird hunter has the stamina of a marathon runner: “They can go 12 to 15 miles if necessary—though I’d recommend only six to eight on a cool day,” says Cohosh. German shorthaired pointers are equally hard to tire out. For optimal fitness, make sure these dogs get at least three hours of outdoor exercise each day.

*These numbers are estimates, as exercise needs vary from dog to dog. Get your pup a checkup to ensure he’s fit for vigorous exercise, and never run a dog younger than eight months.
