Many tiny hair-like cilia protrude from the olfactory receptor cell's dendrite into the mucus covering the surface of the olfactory epithelium. The surface of these cilia is covered with olfactory receptors, a type of G protein-coupled receptor.
Respiration -10 to 30. The normal respiratory rate for dogs is 16 to 20 breaths per minute. The normal heartrate is 70 to 160 bpm. Large dogs tend to have slower heart rates so your dog should be in the 70 to 120 bpm range. This varies according to the cardiovascular fitness of the dog, too.
Canine normal body temperature range is 100.5 - 102.5 Fahrenheit (38 - 39.2 Celsius). A body temperature below 100 or above 103F warrants a call to your veterinarian. Body temperature in dogs is most often measured rectally, ear thermometers can also be used, but it can be difficult to get an accurate reading.anine normal body temperature range is 100.5 - 102.5 Fahrenheit (38 - 39.2 Celsius).
