In 1861 Bummer rescued another dog from a fight with a larger canine opponent. The rescued dog was badly injured, with a deep wound on his leg, and was not expected to live. Bummer coaxed him to eat, brought back scraps from his scavenging missions and huddled next to him to keep him warm during the night. The injured dog quickly recovered and within days was following Bummer as he made his begging rounds in the streets. His remarkable recovery earned him the name Lazarus, and he proved to be an even more prodigious ratter than Bummer. As a team they turned out to be exceptional, once finishing off 85 rats in 20 minutes.
