While some dogs choose a single person to latch onto emotionally, some dogs love social experiences with humans and have big groups of humans they're friendly with. Bonding time with a range of people aside from the primary caregiver can be great for socializing dogs and stimulating their brains.

The methodology of observing the dogs freely exploring the experimental area allowed us to determine the smells that were the most attractive to them (food, beaver clothing). Our study shows that dogs interacted more frequently with the scents of blueberries, blackberries, mint, rose, lavender, and linalol.
So, dogs know a person's individual smell and when illness changes that smell, dogs can notice that, too. Even humans can observe the scent of sickness with some health problems. For example, diabetic ketoacidosis can cause fruity or acetone-smelling breath.
