…I don't think Not-Piotyr will be happy about this.
"Holy heck, you weren't kidding about the dog. Is she -"
"Stuck? Yeah."

"Lets not go near her," says Bina. "Ever."
"That's seems like the best plan," says Kendra.
The enormous animal strains forward, not thrashing as before, just a constant straining reach. It's no use though, as it doesn't seem able to move it's left front leg.
'I'm in shock, right?' thinks Bina. 'I should be in shock. A normal person would be in shock right now.'
"Is there a portal out there too?" asks Kendra.
"I don't think so," says Bina. "It's more like she rebuilds herself out of the mud."
"Huh."
"Yep."
There's a pause while they both stare at the dog.
How's closing that portal coming?
"We should probably turn off the time machine, you think?"
"Yes! Lets do that!"
