Why You Should Not Split Heartgard Medicine in Half
We get it. Taking care of a dog does cost quite a fair amount of money, especially when it requires medicine regularly.
Lots of pet owners we speak to have similar concerns, thus resorting to some actions such as:
- Cutting down the budget
- Reducing costs by trying to find alternatives
- Splitting up medicine in order to give two or more dogs in their household
However, in order to ensure the health of your dog is in the best order, it is important to give them the exact dosage that the vet prescribed.
Skimping on them might lead to very undesirable effects and harm your dog!
With that out of the way, read on for some of the key reasons you should not cut Heartgard Plus in halves.
1. Not having the right amount of medication
The majority of heartworm preventive medications come in the shape of delicious soft chews or flavored tablets.
Additionally, they are combined with medication like ivermectin meant to ward off heartworms or other parasites.
If you divide the medication in half, one half might have all of the medication while the other might not.
The required medications are fully dosed in the pill, but they are not dispersed uniformly across the entire pill.
That is the main reason why you should never attempt to split Heartgard into halves or any medication for that matter.
2. Lose efficacy
Another important thing you should know is that when you split a Heartgard tablet or soft chew in half, it will start to lose its efficacy quickly.
By the time you reach the next month when you want to feed your dog again, the medication is very likely ineffective already.
3. Not recommended by the manufacturer
And lastly, the manufacturer of Heartgard Plus has stated clearly in its factsheet that the dosage must be administered whole and does not indicate anywhere that it is safe to split in half.
Assuming that you feed your dog halves only and end up not being able to prevent heartworm in it, I am sure the manufacturer can excuse itself from being responsible.
There is also lots of advice from vets online to not split the medicine in half.

Can I Give My Dog a Lower Dose of Heartgard?
Some pet owners might be concerned with overdosing, especially when they have very small dogs.
That’s a legitimate concern.
If my dog weighs only 3 pounds or less, and you are asking me to use a medicine suitable for a dog up to 25 pounds, I would naturally be quite worried.
However, we have checked with a few vets and luckily, there is almost zero chance of your small dog overdosing on the medicine.
Problems only tend to arise due to allergies, rather than the medicine being too much.
You may wish to verify this is your vet too if you are still worried.
Alternatively, you can also consider other types of heartworm medicine such as Interceptor Plus.

Can I Give My Dog a Higher Dose of Heartgard?
There is no need for you to give your dog a higher dose of Heartgard.
However, if you accidentally gave your dog an extra dose once or twice, it will be fine and won’t have any significant unpleasant symptoms at all.
This is because both of its active components, ivermectin and pyrantel pamoate, have exceptionally broad margins of safety.
