Some pet owners think so, and believe that vaccines are the cause. The question was originally raised by the British television show Good Morning Britain in April 2018 when they put out a call on Twitter to interview skeptical pet owners.

Instead, Dobias opts for checking a dog’s immunity levels and antibodies at 12-weeks-old to decided whether or not he would recommend vaccinating a dog.
