This treatment is safe to use and has no side effects when administered at normal dosages in dogs that aren’t allergic to them, although caution should be used when administering them to Collie breeds of dog.


► Proven, efficacy against heartworm larval stages.

►Safe to use in breeding stock can be administered to pregnant and lactating bitches, stud dogs, and young puppies (from 6 weeks of age).

►Easy to administer.

►When administered at normal dosages in dogs, side effects are rare (unless allergic – which is also rare).


Why should I treat my pet for Heartworm?

Heartworm is generally spread by biting insects, especially mosquitos. Don’t think that just because your pet is an indoor animal, they are safe, we have all been bitten by a mosquito in the house or the car at some point in our lives…so can your dog.

Obviously tropical areas have a higher incidence of mosquitos and Heartworm, however, studies in foxes have shown that even in Melbourne suburbs, Heartworm prevalence can be as high as 7%, and in Sydney suburbs as high as 9%. While there have been no studies in companion animals to compare this to, it is reasonable to assume that almost 1 in 10 untreated pets may be affected by Heartworm.

Heartworm can be bad news for dogs. The adult worms set up shop in the heart, surrounding blood vessels, and lungs, causing damage to these major organs as they do so. Symptoms are as a result of heart failure, and in dogs can include:

  • Lethargy and loss of energy when exercising
  • Coughing or difficulty breathing
  • Weight loss
  • Swollen belly
  • Sudden collapse
  • Sudden death

These parasites are discreet, that is, they can hide in your pet for a long time before they begin to show signs of an infestation because they are slow to mature. Once mature, the adults start shedding microfilaria into the blood, ready for a mosquito to transfer to another dog.

Treating a heartworm infection is costly, risky, painful, and prolonged. As with most things in life, prevention is much better than cure.

Should you test your pet before starting medication with Saint Bernard Heartworm Tablets? That depends on a few things:

1)     If you have never used Heartworm prevention, it is highly recommended that a test be performed before starting treatment. It is a wise idea to do a second test, 6 months after starting treatment as the test will only detect adult worms and the larval stages can take up to 6 months to develop into adults.

2)     If you are more than a month overdue for your treatment, it is advisable to consult with a veterinarian, who will likely advise you to restart the medication and test 6 months after restarting medications.

3)     If you have been up to date on a different type of Heartworm prevention, you do not need to test before switching over to this medication.
