Your Indoor Pet Isn’t Safe from Parasites

By Randi Lintrup, DVM, Veterinary Manager, MSD Animal Health Nordic

It’s easy to believe that a cat lounging on the sofa or a dog spending most of the day indoors isn’t at risk from parasites like fleas and ticks. Unfortunately, that’s not the case.

Parasite risk depends on lifestyle and location. Dogs exploring the bush, parks or even gardens can be exposed to ticks and fleas. Indoor cats and dogs can also be at risk, as fleas thrive inside homes and parasites like mosquitoes can fly indoors. Pets travelling with their owners may encounter parasites not usually found in their home region.

Fleas: More than just an itch. Fleas don’t just cause severe itching, they can trigger skin disease, spread infections, and even transmit tapeworm if ingested. Adult fleas on your pet are only 5% of the problem; the majority of eggs, larvae and pupae are hidden in the environment. One female flea can lay up to 50 eggs per day, making infestations fast-moving and difficult to clear without continuous treatment.

Ticks: Not just in the countryside. Ticks are commonly found in parks and gardens as well as rural areas, spread widely by wildlife and migratory birds. Some ticks can complete their entire lifecycle indoors, creating a serious household problem. Beyond irritation, ticks can transmit dangerous pathogens to both pets and people, sometimes with fatal consequences. Daily checks are important, but research shows visual inspection alone isn’t enough for protection [1,2].

What should pet owners do?

Protect pets preventatively, even if they spend most of their time indoors.

Treat all pets in a household to prevent re-infestation.

Consult your veterinarian for the right preventative care, tailored to your pet’s lifestyle and local risks.

Five quick facts about parasites:

  1. Flea dirt turns reddish-brown when placed on damp tissue.
  2. Flea bites on ankles may indicate an infestation.
  3. For every flea seen, many more are hidden in the environment.
  4. Pets ingesting fleas can get tapeworms.
  5. Visual inspection alone is not enough to protect against ticks.

Don’t assume your pet is safe – talk to your vet about comprehensive parasite protection. And choose Bravecto® to keep your pet safe from ticks and fleas for 12 weeks in a single dose.
