Except the 12th Amendment says:

But no person constitutionally ineligible to the office of President shall be eligible to that of Vice-President of the United States.

So the only possible way this could work is if Trump got elected to Congress, was voted Speaker of the House, then both the President and Vice President resigned. Which seems far fetched.

I read in another article that the dog that died had recently come back from a medical procedure at the vet, and was being kept in a crate. The two that survived had access to a dog door so presumably were able to get food/water outside.
