Just take good care of your dog, feed good dry not supermarket junk, and make sure she is up to date on vaccinations - she should live a good, long life. Sounds as if you are doing all the right things already.
The average commercial jet liner travels about 550 mph, and the Earth is around 26,000 miles in circumference. If a commercial plane could make the trip without refueling, it would take over 47 hours. A large commercial jetliner has a range of about 5,000 miles, so it would need to land and refuel several times.
I would develop a little bit Brent's reply: my estimate is on average ~ 100 000 km (or 2,5 times around the Earth) The radius of the Earth is 6371 km. Then the the route around the World is equal to 40 000 km. If a person goes per day 10 km, it will take him 11 years to go around the world. However, on average people are not going 10 km per day. Usually, it is 4000-6000 steps per day or 3-5 km per day. Thus, per year it will be equal to ~1500 km, in a lifetime ~100 000 km (2,5 times around our Planet).
