The walking is great for you. Getting out of the house everyday wasn't a given for me since I work remotely. And doing this chore every day just makes you like the little guy more.
I'm not sure plugging the dog's batteries in will have the same effect.
Took 9 years for my other half to convince me to get a dog, now I'm a fully committed dog person.
We can't go on vacation, or even have a night out somewhere else, without planning and paying for them to be hosted somewhere.
I love my dogs, but I'm looking forward with both dread and hope for the days they will no longer be around.
A dog that could be turned off would be much better in this regard.
He can stay inside for 12 hours at a time without issues. He would be fine at a kennel.
However, I have to take him out for walk more than an hour EverySingleDay. So, I have to spend more than 400 hours a year, i.e. 4000 hours for ten years. To be honest, spending 4000 hours is enough for making you a semi-professional in any fields. So, I don't recommend having a dog, unless you are literally CRAZY about dogs.
