We are also to the point of having to carry our Pistol Pete outside at times at home but always while traveling. The motor home stairs are not an option for him to even try now. Make no mistake he is still happy, eats well, wags like a whirlwind, and finds joy in smelling around.... like your Ricky.
With that said, we do still attach a leash to his collar because he has no problem with wearing it and he is able to walk around some while we are camping but I know that won't last forever. Our days with him are dwindling down to a precious few. Will it be weeks or months? Time will tell.....
If anyone wants to make some sort of judgment about any decisions we make with our Petey, it would not be any of their business and I would tell them so, post haste.
I am sure you take excellent care of your pets, at all ages. Give them all ear scratches from me please. Enjoy each day, cherish the time you have with them, because as we all know time passes far too quickly.
