How far dogs can smell depends on many things, such as the wind and the type of scent. Under perfect conditions, they have been reported to smell objects or people as far as 20km away.
To get to the heart of your question, male dogs have excellent senses of smell and can sense an intact female in heat up to 3 miles away. Dogs have geographic territories, and they can generally detect any intact females within those boundaries.
Dogs have a strong sense of smell so it is not really surprising that they can smell their owners as they are coming home. Dogs know the smell of their owners very well. Their scent lingers long after they leave home and gradually diminishes over the course of the day only to return back strongly when they arrive home.
Humans each have a unique innate scent that enables dogs to tell one person from another. Our dogs do not need to see us to identify us.
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.
Can dogs sense human arousal? There is no evidence thus far that dogs actually understand what is happening when two people have sex. They likely recognize the smell of pheromones when people become aroused and other scents associated with people engaging in intimacy.
It turns out that both cats and dogs are able to detect menstruation by odor and hormonal levels. Of course, they don't actually have any scientific concept of what's happening in your uterus, but they do know that something is going on.
Dogs Prefer Adults — Particularly Women
A dog's preference for one person — or type of person — over another has a great deal to do with socialization. Dogs don't, as a rule, dislike men, but most dogs are cared for by women, and are thus more comfortable around them.
However, canines can figure out the gist of what we want and gather a lot of information from our body language, tone of voice, the rhythm of our voice and intonation of speech. What your dog hears when you talk to him is his favorite melody – your voice.
Just like their human pals, dogs are likely to choose a favorite person based on a number of factors. Some of these include the person's demeanor, interactions with the dog, and how well the person helps meet their basic needs.
In other words, dogs can start missing their Owners from the moment they part ways. After that, keep missing them more and more for up to two hours. Beyond the two hour mark, they begin a plateau of melancholy until they see their Owner again.
Dogs know based on their experiences.
Environmental stimuli like light shifts, sounds, smells, and even cues you can't pick up on can play a role in your dog's ability to sense when you're coming home.

If we look at this behavior from a scientific standpoint, your dog can sense love because they can sense the levels of oxytocin in your brain rise when you are feeling happy to see them. They use their sense of smell to detect this rise in your hormone, oxytocin, which is your happiness hormone.
Can they hear a heartbeat from across the room? Well, surprisingly, the answer is yes! Dogs' senses of hearing are so good (and so much better than ours) that it's likely that they can hear human heartbeats, as well as other animals' heartbeats as well.
Dogs communicate with us all day long, and whether we know it or not, we're talking right back to them through a variety of verbal and nonverbal cues. In fact, a recent study concluded that there are 19 different signals that dogs use to talk to us.
According to Dr. Roberts, around 75% of a dog's sleep happens at night while the rest occurs in the daytime. The average dog sleeps around nine hours in a night and three hours during the day. That means humans can sleep with their dog each night.
In general, Bray says dogs probably think about all the staples in their lives, from food and play to other dogs and their pet parents. Like humans, how much time they spend pondering a specific focus “depends on the dog and their individual preferences and experiences,” she notes.
Male dogs are usually more affectionate than females, and some positively crave human attention. You'll find it's always you who brings the cuddling and fussing to an end – he could happily go on like this all day!

But, dogs generally tend to be more attracted to a specific set of behaviors that are exhibited mostly by adult women. It's not that dogs are exclusively attracted to female adults.
Generally speaking, a healthy dog with a short, smooth coat and no skin problems doesn't need to be bathed often. In most cases, dog baths are more for the benefit of their pet parents than for the dogs themselves. Even so, it's a good idea to bathe your pooch at least once every two to three months.
