Safest flea prevention for puppies with young children

A 5-month-old German Shepherd with young children in the house — you're absolutely right to think carefully about what you use. Before I get to prevention products, it's worth knowing that treating fleas effectively means treating both the dog and the home: around 95% of fleas actually live in carpets, bedding and furniture rather than on the dog itself, and no single product covers both. That said, you're asking about prevention, so let's start there. What's your puppy's current weight, and have you noticed any fleas yet or are you purely looking to stop them before they start?

18kg at 5 months — she's going to be a big girl! That weight actually puts her in a good spot for options. Given your priority around the children, I'd steer you away from spot-on treatments that sit on the coat, because there's a window of a few days after application where you'd want to limit contact. For a family like yours, a chewable tablet is the cleaner choice — nothing on the fur, no transfer risk to little hands at all.

Yes — at 5 months and 18kg, she's old enough and heavy enough for Bravecto Chewable Tablet for Dogs. One tablet covers her for 12 weeks against fleas and ticks, which means you're only dosing four times a year rather than monthly. It's a prescription product in the UK, so you'll need a vet to sign it off, but most practices will do that at her next routine appointment or via an online vet prescription service. Because there's nothing applied to the skin or coat, your kids can cuddle her freely from day one. It's well-tolerated in large breeds and widely used — it's genuinely what I'd choose in your situation.

Since you're getting ahead of it before any infestation, you don't need to treat the home right now — that's the ideal position to be in. Keep on top of regular hoovering, especially around her bed and favourite spots, and wash her bedding on a hot cycle every couple of weeks. If you ever do spot a flea on her, act on the home immediately — a household spray like Indorex Defence is the one I'd reach for — but for now, Bravecto on the dog and good hygiene habits is a solid, low-stress routine for a busy family.

Perfect plan. Mention her weight when you call — they may be able to process the prescription without a full appointment if she's already a registered patient. You're doing exactly the right thing getting this sorted early with a puppy. Enjoy her — German Shepherds at this age are wonderful chaos.
