ver wonder why dogs obsessively inspect moles or skin blemishes? While it looks like playful curiosity, this behavior is deeply rooted in canine evolutionary biology.

In the wild, pack members perform allogrooming—using their small front incisors to gently nibble away ticks, fleas, and foreign debris from one another. A raised, pigmented bump acts as a tactile trigger, instantly activating this ancestral grooming instinct. Rather than mistaking it for food, your pup might simply be trying to protect their favorite human from what they perceive as an unwanted parasite!
