One way of figuring this out in a way that would provided the most info to you and be specifically tailored for yourself is by clicking on the "Trip Planner" button. Since your dog will accompany you, if he/she is trotting along beside you you might consider looking for veterinarian services along the route. If the web site doesn't have that, try a duckduckgo search for the villages you'll pass thru.
From there you can pick any starting point, and see what services are along the 60 miles you will travel from your starting point.
Also, something to think about is whether you mean 60 miles out and 60 miles back or 60 miles round trip.
Just as a tip (perhaps incorrect, but remember what you paid for it!) I've read and seen that the most interesting locks are toward western part of the canal at Lockport. I've enjoyed that part. Beautiful sweeping scenes of farmland, open sky, little danger for a dog, and nice villiages along the way that have essential services. However, I'd be very cautious with a dog going thru Rochester (where there are interesting locks). Maybe you could start west of Rochester and go west, or start in Lockport and go to the western part of Rochester.
Check out the "Towns and Services" menu at the top of the page, and make up your own mind.
