I try.
Yes, ITK, Keiki is doing quite well. Actually some of her health problems improved when we got her back (?). Weird. But she is old.
I often don't let my children guests play with her. She never particularly liked kids, and geriatric dogs and young children can be a bite waiting to happen. I have one 6 year old friend who is good, but many of the others get warnings (kids and parents) to just leave her alone. It can be hard because a lot of children simply can't resist something smaller and weaker than them (she's a 13 year old, 13 lb, skinny Jack Russell). So far she's not bitten anyone (snapped, though), but she has a lot of spots on her body she just doesn't want anyone to touch. Especially on her head.
Only you can decide when to put down a beloved pet, but it helps to have your vet's advice along the way. Sometimes hiding from or running away from loved ones is a pet's way to say good-bye. Fang did try to hide from us for a few days before I realized the disease was causing her unbearable pain. And Keiki had shown signs of seizure activity for days before she wandered off, so we assumed that was the case. That has dissappeared, and after her sores healed, her coat came in winter-heavy (something that never happens in the spring). But I do see her stopping and just staring off into space and she sleeps A LOT.
While I do not withhold water, per se, before her mom got kidney disease they used to have a bowl of water in the bedroom at night. Once that started (with my vet's approval), I no longer leave water in the room. I'm an insomniac anyway, and getting up for potty or watering breaks at 3 or 4 aren't that big of a deal.
