Lambent Dogs were normal dogs infected by Imulsion and turned Lambent. Along with Lambent Bulls, Lambent Dogs proved Damon Baird's theory that Lambency was capable of jumping the species barrier.
"'Shit! It's a dog."

During the Lambent Pandemic, Alex, Anya, Sam and Bernie came across what they initially thought was Polyps given the sheer speed and agility after it popped out of a Lambent Stalk. However, upon closer inspection, they discovered that these were dogs infected with Lambency.
Although it resembled, behave and acted like a dog, they were covered in Imusion blisters and were extremely aggressive. The four battled dozens of these lambent dogs, however, one of them leaped towards Mac. A devout dog lover, Bernie panicked towards the well being of Mac who also leaped and battled with one of the infected dogs. Fortunately Mac escaped unscathed.
