Given how seasonally significant ticks are in Sweden, covered in detail in the Health section, it's worth knowing where to buy prevention products once you're there. Swedish pharmacy chains such as Apoteket, Apotek Hjärtat and Kronans Apotek stock basic over-the-counter (receptfria) tick-prevention products for dogs and cats, sold without a prescription, alongside their human-health business.

Products vary in how long they last — some are formulated to cover an entire tick season with a single application, while others need reapplying monthly — so it's worth asking the pharmacist directly which suits your situation and how long you'll be in Sweden, rather than guessing from the packaging alone.

For anything beyond basic tick prevention — a stronger combined parasite treatment, a specific medication for an existing condition, or anything a vet has specifically prescribed — Swedish pharmacies generally require a prescription, the same as most of Europe, so carry a copy of any relevant prescription or vet letter from home if you expect to need a refill while travelling.
