Heartworm and Flea Tick Prevention Calendar

Heartworm prevention is monthly. Flea and tick prevention is monthly. Dewormer cadence varies by region and vet. The single most common reason puppies and adult dogs end up with heartworm or tick-borne disease is not a failure of the preventative product. It is a missed dose followed by a second missed dose. The pill in the kitchen drawer that nobody remembered to give.

The Parasite Prevention Calendar is the document that prevents that.

What this document does:

It tracks monthly parasite preventatives across a full calendar year, with a row per month and check-off columns for heartworm and flea-tick treatments. Hang the sheet wherever you keep the medication. Check the box on the day you give the dose. Patterns emerge fast: most missed doses cluster around the same month or two when the household is busy.

The document also captures the products in use (heartworm, flea-tick, dewormer, and any other) along with the dose, frequency, and start date. That product reference matters when a vet asks what your dog is currently on, or when a boarding facility wants confirmation before accepting a stay.

What is included:

• 1-page parasite prevention tracker
• Dog identification section with name, date of birth, and current weight (which should be updated quarterly since dosing is often weight-based)
• Preventatives in use table covering heartworm, flea-tick, dewormer, and other categories with product name, dose, frequency, and start date
• Monthly dose log for all 12 months with click-to-check boxes for heartworm and flea-tick plus date-given and initials columns
• Print version with paper checkboxes for handwriting
• Digital version with clickable form-field checkboxes that work in Word, Pages, and as a fillable PDF

Format and how it works:

Print version and Digital version, both as Word .docx and PDF. The Digital PDF has true AcroForm checkbox fields. Click a checkbox in any modern PDF reader, save the file, and the checked state persists. Most owners keep one filled copy on the fridge or with the medication, plus a saved PDF on their phone so the latest status is always accessible.

Use one tracker per dog per year. Save the previous year's tracker as a permanent record before starting fresh in January.

Why this version is different:

Generic medication trackers do not understand the cadence quirks of dog parasite prevention. Heartworm needs to be given within 30 days of the last dose to maintain efficacy. Many flea-tick products lose effectiveness 28 to 32 days after application. Some dewormers run on a quarterly schedule, not monthly. This tracker organizes those differences into a single sheet so the owner does not have to remember three different cadences across three different bottles.

The tracker is not a substitute for the dosing instructions on each product label. It is the master log that tells you whether you actually followed those instructions this month.

Who this is for:

For new puppy owners starting parasite prevention for the first time, typically around 8 to 12 weeks depending on the product. For owners of adult dogs who have ever missed a dose or two and want a system that prevents that from happening again. For owners in heartworm-endemic regions (the southern US) where missed doses carry real consequences. Pairs naturally with the Vaccination Record and the Vet Visit Tracker.
