Fleas, ticks, and worms are among the most common health issues new dog owners face — and the good news is they're largely preventable with a simple routine. Some, like certain ticks and worms, can cause serious illness, so prevention is far easier than treatment. Here's how it works, with the reminder that your vet will recommend the right specific products and timing for your area.
Fleas
Fleas cause itching, skin irritation, and can lead to infestations in your home that are a nightmare to clear. Modern preventatives (spot-ons, chewables, or collars) stop them before they take hold. Prevention year-round is often recommended, especially in warmer climates where fleas never fully die off.
Ticks
Ticks can transmit serious diseases, and in some regions certain ticks can be life-threatening to dogs. If you live in or visit tick-prone areas, prevention is critical, and you should check your dog's coat after walks in grass or bush. Ask your vet which tick preventative is right for your region — this is one where local advice really matters.
Worms
- Intestinal worms (roundworm, hookworm, tapeworm, whipworm) are common, especially in puppies — many are born with or quickly pick up worms
- Heartworm, spread by mosquitoes, is far more dangerous and is prevented with regular medication in at-risk areas
- Puppies are usually wormed frequently early on, then on a routine your vet sets
- Some worms can transfer to humans, so prevention protects your family too
Flea & Tick Prevention
There are many effective options — spot-ons, chewables, and collars. The best choice depends on your dog and region, so use this as a starting point and confirm the right product with your vet.

A simple, consistent prevention routine spares your dog discomfort and serious illness — and your home an infestation. Because the right products and schedules vary so much by region (especially for ticks and heartworm), make this a conversation with your vet rather than guesswork.
