It is fairly simple to
notice flea infestation on your dog. What is more, once you get about
it and are conscientious, it is fairly easy to get rid of it, too.
However, there are other different parasites your pet may be infested
with, which can lead to severe health problems and which, alas, are
not that easily noticeable.
One of such parasites is
heartworm. It is transmitted by parasites and, once it has invaded a
pet's body, it may take it up to two years before any symptoms are
visible. To make things worse, over the first six months no symptoms
whatsoever are detectable, even in the vet's lab. Most often, the
larvae settles in the heart and only once it has matured will any
signs be noticeable. If, although rarely, the larvae end up in
unusual areas, such as the eye, brain, or an artery in the leg,
different results may be spotted, eg. blindness, seizures or
lameness.
