So they have cons as well! That sucks!

Hard To Metabolize For Some Dogs

A possible con is that any collie family dog breed may have a genetic mutation that affects their ability to metabolize some heartworm prevention medications of the ivermectin family (like Proheart or Heartgard). However, this issue does not affect Bichons.

Monthly Expenses

Another con is that you need to spend money every month on a prevention medication, whether your dog is exposed or not.

But you can take it as some sort of insurance against infections borne out of infected mosquito bite.

And always keep these possible risks in mind.

What To Look For When Buying Heartworm Preventives?

wondering cute dog

So, follow these to find the best heartworm prevention.

There are things that you should always have in mind while you consider buying the best heartworm preventive medications.


There are various forms of heartworm preventives.

Among the most common forms are topical medication, shots, and chewing tablets.

They come in various forms that make for easy administration. But before purchasing the medication, you need to consider the behavior of your pet.

If he has an aversion for injections, stick to chewing pills.

Topical medication is the best choice for dogs that are intolerant to strange flavors.


The main reasons for giving dogs heartworm prevention is to keep away infections.

Preventives are costly. But as pet owners, it's our obligation to see to the optimal well being of our fido.

However, a costly drug can dent a household's budget.

You need not buy product based on pricing alone.

Sometimes, the cost doesn't even infer the efficiency of a product.

Rather than considering cost, look out for the drug's composition and check whether it has the right components and active ingredients.

One can also consider primarily a drug's viability against different parasites.

The greater the assortment of parasites a drug terminates, the more beneficial it is to you and your dog.

Weight And Age

Nowadays it is recommended to weigh your pet before purchasing any heartworm medication.

Most of today's medications are manufactured with dog age and weight specifications.

Giving your pet any medication without accurate knowledge of its age and weight may result in fatalities.

For instance, giving 1 entire bite to a 6-week old dog can cause an overdose.

Measuring your fido's bio data in a timely manner can help avert costly mistakes.

The correct knowledge of its age and weight is one of the basics of a proper, seamless prescription.

A common rule of thumb is the heavier the pet the greater the amount of solution needed.

This is more true if the solution is in a powdery form.

If the quantity of the medication administered to a big dog is insufficient, a potential infection from various parasites remains imminent. 


A product's list of ingredient determines the product's effectiveness.

Certain ingredients are known to prevent possible complications from attending the drug administration, like a dog being susceptible to some prescriptions.

It’s always advisable to consult your veterinarian about possible allergic reactions to a chosen dog medication.

The most widely used ingredient in heartworm medications is Ivermectin --an anti-parasitic substance that eradicates heartworms, scabies, head lice and other types of infestations.

Moxidectin is also widely used. It eradicates intestinal worms. Another is Selamectin, repels insects, ear vermin, sarcoptic mange.

It is always better to purchase an item that eradicates more than 1 sort of parasite.
