Sharp Mountain, with its many trails, sits directly behind my house. For many years, I ran the trails to find solitude, and soft-surface comfort for tired legs. My Redbone Coonhound, Ruby, logged many miles on those trails with me. Last November, she was diagnosed with a severe liver disease, was given only two months to live, but she fought, and finally lost her battle on Friday. Since her illness, she was reduced to walks rather than runs, and last Wednesday she took her final walk, a brave, but fun, 1-mile trek.
Run with your pups as long as you and they are able. It is good for them and it's good for you. I hope Ruby is running trails and sniffing rabbits in doggy heaven.
