Oh hi, I’m just trying to figure it out! Living in Northern CA, husbanded, gay, and a chronic dabbler. Interested in TTRPGs, video games, PC building, noodling around with Linux, cooking, baking (sweet to savory, especially sourdough), and reading scifi/fantasy.
I’m sorry you’re going through this difficult situation. I wanted to privide my perspective as a long-time shelter employee, once upon a time.
I put in nearly ten years (variously full and part time) at a local animal shelter and can confirm many others’ concerns about senior animal surrenders. It doesn’t usually go well, and is hard for the folks on the shelter side playing damage control. It amounts to shifting the onus of euthanasia from the owner, who the dog knows, to a stranger. Often, shelters will sponsor senior animals’ adoptions (waive the fee), but often, even this isn’t enough an incentive.
Instead of a shelter, you could try reaching out to a privately run rescue, which frequently “specialize” in senior animals and animals with health issues. They aren’t obligated to accept surrenders like a municipal shelter, but the extra effort you go through in placement would mean your senior pup gets place in a home or home-like setting, rather than a room with crates or kennels. Search petfinder.com for rescues in your area.
I also wanted to give you some encouragement for the wellbeing of your other dog. Its important to remember that animal are individuals, too, and handle loss and grief, whether surrender or euthanasia, differently. My dog Louis (now passed himself) was originally one of three and had adapted to the only-child lifestyle without much issue at all.
