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.
Thanks for answering my questions. The 'normal' respiratory rate for a dog is 10-34 breaths per minute...HOWEVER, large breed dogs can be slower and smaller breed dogs can be faster. Add to it the fact that some medications, pain or even just mild discomfort can cause that rate to raise.he 'normal' respiratory rate for a dog is 10-34 breaths per minute...HOWEVER, large breed dogs can be slower and smaller breed dogs can be faster.
