Why do dog roll in dead things?
Most animal experts think the behavior is a likely a holdover to dog's ancient ancestors, the wolves, known to roll around in smelly stuff and dead things to mask their odor on a hunt. “Wolves camouflage their natural odor this way to “hide” from prey and hunt more successfully,” says Sievert.
Dogs roll in disgusting stuff to mask their natural scent, allowing them to camouflage themselves and be sneakier hunters.
The most popular theory is that it's a holdover from their wolf ancestors: dogs roll around in smelly (to us: the most disgusting) things to camouflage their own natural odor. Masking their scent would have helped wolves sneak up on prey, enabling them to be more effective hunters.
Fortunately, every one of them means he likes you. A lot. If your dog runs the roost, this cute little behavior might actually be a way of displaying ownership over you. Dogs have scent glands in their faces, so when your furry child rubs its head on you it might actually be an attempt to mark you with its scent.
Many dogs are known for immediately rolling on freshly-washed laundry that you've laid out to put away. The reason for this is that dogs identify their family mostly through scent. When a dog rolls on clean laundry, he or she may be trying to redistribute their scent to make you identifiable as part of their family.
You may find them pleasant, but many dogs dislike their odor. As a result, as soon as your just-bathed dog gets the chance, he finds something that smells more acceptable to him—garbage, dog feces, animal carcasses—and starts rolling around in it.

Dogs prefer the smell of things more odoriferous and complex like garbage, carcasses, rotting food, poop, and anything else stinkier and more pungent than the “lavender” shampoo smell.
Another explanation why a dog might roll around in the remains of dead animals is so that they may cover their tracks. This also is a potential inheritance from their wild ancestors. A wild dog's prey also has a well developed sense of smell and can detect a predator if they catch it on a prevailing wind.
Key takeaway. Dogs sniff people's crotches because of the sweat glands, also known as apocrine glands, that are located there. Sniffing these glands gives a dog information about a person such as their age, sex, mood, and mating probability.
Why do female dogs roll in dead animals?
They initially learn to distinguish the smell of feces from food and so on. A dog's sense of smell is so strong that it is just a piece of cake for them. Females thus roll in dead animals and bring the remains of the scent back to their families.
