I have a pack of 3 dogs, one with red, one with yellow, and one with a pink collar.

I don't know why but my Red and Pink dog would disappear at the strangest times, I'd log into my game, and then i'd see my Yellow, and Red dog. Other times, the red one would be gone, but then my pink dog would appear.

The yellow one has never gone missing once, and they were always sitting down when they disappeared.

It'd change everytime I relogged.

I put all 3 dogs in one place in my house, quit and relogged. Each time there'd be one dog that was missing.
