When I moved from the city to the country, the first thing I did was have an attractive dog run built right off my deck, Lattice and 4x4 used, 4 ft high 32 ft long 8 ft wide. Then I had a special screen door built with a doggie hatch. My oldest was 10 years old and would never walk through a door unless it was fully opened, I didn't think she would use the doggie hatch, my baby was 5 y/o, I knew she would have no problem with the hatch. I guided the 10 y/o through the hatch 4 or 5 times, she had no problem, both used the hatch that led to the deck then 3 steps down to the dog run. So yes, you can train an older dog to use a doggie hatch.
