As dogs grow older, their performance and ability to learn new smells is reduced. Female dogs have a greater sense of smell than males. A variety of diseases can decrease a dog's sense of smell, such as canine distemper and nasal mites. Dogs have an enhanced sense of smell when fed a high-fat, low-protein diet. There are a number of theories ...
The odor associated with dog paw pads is much more noticeable on dogs with moist paw pads than on those with dry pads. Dogs also have numerous apocrine glands in their external ear canals. In this location, they are referred to as ceruminous glands. The ear canals also have numerous sebaceous glands.
A female dog is usually diestrous (goes into heat typically twice per year), although some breeds typically have one or three cycles per year. The proestrus is relatively long at 5 to 9 days, while the estrus may last 4 to 13 days, with a diestrus of 60 days followed by about 90 to 150 days of anestrus.
When your dog is in heat, you have two goals: keep her comfortable and prevent her from getting pregnant. Unless you are a licensed breeder who knows what’s up when it comes to caring for a ...
Although dogs are capable of following both visual and olfactory cues, it appears that scent is their most effective source of information. [4] Equipped with enhanced physical and neurological olfactory structures, a dogs sense of smell is much more advanced compared to that of humans. [5]

In this view, a decrease in the fraction of functional OR genes would cause a reduction in the sense of smell; species with higher pseudogene count would also have a decreased olfactory ability. This assumption is flawed. Dogs, which are reputed to have good sense of smell, [43] do not have the largest number of functional OR genes. [41]
