Dog Flea & Worm Treatments

Petworld understands that flea and worm prevention is essential for keeping Irish dogs healthy and happy. Parasites like fleas, ticks and worms not only make dogs itchy and uncomfortable, but can also carry serious diseases. Tick and flea bites “can cause bothersome itching” and even “dangerous diseases,” so taking early action is crucial. In Ireland’s mild climate, flea infestations can happen year-round, so regular treatment is recommended. At Petworld, we stock every type of treatment to suit your dog’s needs. Spot-on (e.g. Fleaway, Bob Martin) are easy to apply between the shoulder blades and typically protect for about a month. At Petworld, we stock every type of treatment to suit your dog’s needs.

Oral tablets/chews (like Wormaway) work systemically to kill fleas, ticks and worms from the inside out. Sprays and powders can be used on a dog or in the home: Johnson’s Flea Spray and similar products kill adults and prevent eggs from hatching. Medicated shampoos with anti-flea ingredients provide immediate relief for heavily infested pets.

Frequently Asked Questions

How often should I treat my dog for fleas and worms? +
Vets generally advise year-round flea prevention (usually monthly spot-on or tablet treatments) and regular worming. For example, worming is often done every 3–4 months for healthy adults. Puppies start worming very early: as one Irish product guide notes, pups can be treated safely from 2 weeks old, repeated every 2 weeks until 12 weeks of age, then every 3 months thereafter. Flea treatments (spot-ons, tablets, etc.) are typically applied every 4 weeks.
What’s the best flea treatment for dogs in Ireland? +
There’s no one-size-fits-all “best” product—it depends on your dog’s size, age, and lifestyle. Many owners and vets recommend proven spot-ons or chewables from top brands (e.g. Fleaway, Bob Martin) for broad protection. Collars can also be effective. Always follow instructions carefully and consider talking to your vet for a tailor-made choice.
Can puppies safely use flea and worm treatments? +
Yes, most flea and worm products are labelled for puppies (when they reach a certain weight/age). For example, many spot-on flea treatments are licensed from 8 weeks of age, and wormers may be suitable from as early as 2 weeks. Always check the product label for the minimum age/weight. There are puppy-specific formulas available, so choose one meant for young dogs.
Are natural flea and worm treatments effective? +
Natural remedies (like herbal oils, garlic supplements, etc.) can provide some support and are appealing to many owners. However, for heavy infestations or high-risk pets, vet-recommended products with proven actives (such as fipronil, imidacloprid, afoxolaner, etc.) are usually more reliable.
Do I need a prescription to buy dog dewormers or flea products? +
Most over-the-counter flea and worm treatments for dogs in Ireland do not require a vet prescription. However, some oral treatments do require a vet’s prescription. When in doubt, check the product description—Petworld clearly labels any prescription-only items.
