What Is The Purpose Of A Rabbit’s Dewlap

A dewlap is developed when a female rabbit is spayed and enough to reproduce in an early stage. They use their dewlap in making a nest when it is nearly their time of the arrival of their babies.

During the rabbit’s nesting stage, the female rabbit pulls out her hair in her dewlap and starts building its own nest for her babies and fur to insulate the nest. please read here why is my rabbit shedding

Health Issues Dealing With Dewlaps

Dewlaps indicate how healthy and normal a rabbit could be until this deals with major destructive health-related issues.

Your rabbit might experience difficulty grooming on its own, especially when eating; the folds of its dewlap may have food trapped under it that won’t be able to get by your lovely rabbit.

That trapped dirt could cause bacteria that could lead to some serious bacterial infections and, worst, can lead to a surgical reduction.
