What’s one piece of pet tech that actually made day-to-day life easier for your senior dog?

I’m starting to realize senior dogs need a totally different kind of support compared to when they were younger. Little things that never used to matter suddenly do, like getting around comfortably, sticking to routines, or just making everyday stuff easier on them physically.

There’s so much pet tech out now that I honestly can’t tell what’s actually helpful and what’s just clever marketing. Curious if anyone’s found something they genuinely ended up relying on for their older dog day to day.
