We have three dogs, two are "old" (13 and 14 years old) and Sidney, who is one year old. When we take them for walks, Sid is the first to tire out and plop down in the shade to rest, while the old guys just keep plugging along. Is this typical for a one-year-old?
When we take short walks, or walk early in the morning when it is still cool out, he is fine.
