We highly recommend it for
dogs with significant risk factors: a «snub - nose»
anatomy (snub - nose breeds are very susceptible to respiratory infections, have a higher mortality rate, and have a harder time clearing the disease),
heart and / or pulmonary disease (such as
dogs with congestive
heart failure, a history of heartworm infestation, etc), suppressed immune systems (such as after chemo therapy), and competition
dogs (show
dogs, performance
dogs, search & rescue
dogs, etc).
