Factors to Consider

Before purchasing an over-the-counter heartworm prevention product for your dog, there are some essential factors to consider:

1. Effectiveness: Make sure to choose a product that is proven effective against both adult worms and larvae stages of heartworms.

2. Ingredients: It is crucial to check the ingredients in the product to ensure they are safe for your dog. Some dogs may have allergies or sensitivities to certain ingredients.

3. Spectrum of Protection: Some over-the-counter products not only prevent heartworms but also protect against other parasites like fleas and ticks. Consider your dog’s lifestyle and geographical location when choosing a product with additional protection.

4. Age/Weight Restrictions: Most over-the-counter products have age or weight restrictions for dogs. Make sure you select a product suitable for your dog’s age and weight range.

Recommended Over-The-Counter Products

4. ProHeart 6 Injection: This six-monthly injection provides continuous protection against adult worms in dogs weighing at least 6 pounds.

Final Thoughts

It is essential to note that while over-the-counter heartworm prevention products may be effective in preventing the disease; they cannot treat an existing infection. Therefore it is crucial to have your dog tested annually by a veterinarian even if they are on preventative medication.

In conclusion,‘s recommended over-the-counter products provide excellent protection against heartworm disease when used correctly according to their instructions. However, always recommends consulting with your veterinarian before starting any new medication or changing your pet’s preventive regimen.
