Dog heartworm disease is a terrible thing any pet owner will try to avoid. So choosing a reliable heartworm medicine is an important part of being a responsible dog owner. Once you have chosen your preferred type of heartworm pills the task of ensuring your dog never succumbs to this illness is not over.
Before starting any course of preventative heartworm medicine for your dog or cat a trip to the vet is critical. Your vet needs to test your pet to ensure they do not already have a heartworm infection. This is critical because otherwise your pet could actually be made severely ill by the preventative.
The heartworm parasite is passed to dogs and cats via an infected mosquito. The larval worms found in the animal’s bloodstream is the first stage towards developing heartworm disease. Heartworm preventatives do not actually stop infection but they are able to eliminate any parasites in your pet’s bloodstream.
All preventative heartworm medicines target and destroy these larval worms which are then absorbed by your pet with no problem at all. However, if your pet had picked up heartworm larvae last season they may already have matured into much larger adults and started congregating in key heart and lung blood vessels. Now, if a preventative heartworm med is given, these adults may be destroyed which may result in large volumes of toxins being released into your pet’s bloodstream. This, plus the larger more dangerously concentrated dead worms make it much more difficult for your pet to absorb the worms.
Therefore it is critical that your vet confirms your pet is clear of heartworm disease prior to starting those heartworm meds. Otherwise your good intentions good put your pet in more harm. Each spring your pet should be tested for heartworm disease again before you start another course of preventative medicine.
