Around here older people with dogs who walk them at our local, big dog park make arrangements with each other to take each others pets. I haven't done that yet but I'm friend with a few who have done that one of whom I think would enjoy taking Ember if I should pass before them. She has a border collie now so she understands the challenges and she loves Ember. It's mutual.
I just wrote about taking the dog we put my wife's aunt and uncle up to getting in their old age on my diary page, if you're interested. I hope you can find someone to do the same for you. Say say having a dog puts some number of extra years onto your life. Even if not true we know it adds tremendously to our satisfaction as other satisfactions fall away.
Gardening for nature, walks with my dogs and the books I’m reading.
