"We are very upset, as we had high hopes for little Ricky," said Eisermann, who visited Ricky and the other dogs in Odai just a few days before the young puppy passed away.
But Eisermann isn't discouraged by little Ricky's unfortunate death, because there's still too much work to be done for the remaining 680 dogs in the shelter.
"RIP, beautiful Ricky," Eisermann said. "May your death not be in vain."
