As someone who has a large dog with cancer, I don’t know how I could possibly manage her condition if I didn’t have a personal vehicle without it being insanely burdensome. So many appointments and pharmacy visits.
You don’t have to get rid of your car. You just have to not use it overly much. And no, this isn’t an extremely niche case; tons of people have pets and they get sick. And of course humans get sick. I could be having the same problem with a child instead of a dog.
I don’t know your personal situation, but in my city there are lots of car share schemes that are cheap and easy.
Sorry about your dog. But your example only highlights a tabu issue in these discussions, the negative impact that having a pet has. They consume meat, packaged food, are driven around, attack wild fauna (cats especially) etc. Pets is one of the items everyone should cut, but they’re only becoming more common, like SUVs.
