This is a specific conversation about Flea treatment for dogs — getting on top of it fast — ask about yours and get one honest answer for your exact situation.

Before we dig into the branded versus generic question — which is a fair one — it's worth knowing that treating fleas properly means tackling both your dog and your home. Around 95% of fleas actually live in carpets, bedding and soft furnishings, not on your dog, so a single product rarely gets on top of it. To point you in the right direction: what breed and rough size is your dog, how bad does the infestation seem right now, and have you done anything to treat the home yet?
She's a mongrel, about 2 years old, roughly 12kg. I've spotted a few fleas on her but haven't seen them jumping around the house yet. Haven't treated anything else. And yeah — basically I want to know if I need to pay for Frontline or if a cheaper version does the same job.

Good news: for a healthy 2-year-old mongrel at 12kg with an early-stage infestation, a generic spot-on can absolutely do the job. The honest answer is that many cheaper products use the same active ingredient as the big brands — the difference is mostly packaging and marketing. That said, there are cheap products that use older, weaker compounds, so you do need to pick the right one. What active ingredient are you seeing on the label of anything you've looked at so far, or are you starting from scratch?
Starting from scratch really. Just want something that works without spending a fortune.

In that case, my recommendation is Beaphar Spot-On for Dogs — specifically the medium dog version for 10–20kg, which fits her perfectly. It uses permethrin as the active ingredient, kills fleas and ticks, and costs a fraction of Frontline or Advantage. It's widely available on Amazon UK and well-reviewed. It's not quite as long-lasting as fipronil-based products like Frontline, so you're looking at re-applying every 4 weeks rather than every 6–8, but for the price difference most owners find that a straightforward trade-off. One important note: permethrin is toxic to cats, so if you have a cat in the house, come back to me and I'll suggest an alternative.
No cats, just her. That sounds good actually. What about the house — do I need a separate spray?

Yes, and don't skip this part — it's where most people go wrong. Since you haven't seen fleas jumping yet you've likely caught it early, but the eggs and larvae are almost certainly already in your carpets and soft furnishings. Pair the spot-on with a household flea spray that contains an insect growth regulator, or IGR — this stops eggs and larvae developing rather than just killing adult fleas. Indorex Defence Household Flea Spray is the one I'd point you to: one can covers up to 18 rooms and lasts for 12 months. It's a few pounds more than supermarket sprays but it's genuinely worth it. Vacuum thoroughly before you spray, and wash her bedding on a hot wash the same day.
Perfect, that all makes sense. Thanks — really helpful.

You're in good shape — catching it early makes a real difference. To recap: Beaphar Spot-On for medium dogs for her, applied every 4 weeks, and Indorex for the home. Do both on the same day if you can. If you see fleas persisting after two treatment cycles, that's when it's worth stepping up to a vet prescription product, but most early infestations like this clear up without needing to go that route.
