Yes, I've seen a couple in the past 6 months or so, though we don't use a huge amount - switched most to Bravecto.

yes, exactly the issue we had here. We have a whole checklist we go through including what the dog was washed with etc, whether fat full fed fleas, immature, the whole gauntlet-and once we switched products, same owners had success. I suspect Scotland makes it easy for flea products to work but where you don't get -degrees in the soil for several days then the intermediate stages can persist and you get overwhelming numbers once they do hatch. Everything I learnt about fleas in UK lasted about one month in Australia, the flea issue is all year round and at very high background levels ready to hatch. The cat Selamectin worked a bit better than the dog but Advantage outperforms it time on time here for us. And now its all Bravecto

[quote user="robloxley"]9/10 times when flea control fails it turns out to be something other than the active ingredient of the spoton, be that environmental control/ other non-treated pets/ underdosing etc[/quote]I agree which is why I usually take it with a pinch of salt but now had several who I would trust coming in with a problem.

We use tons of selamectin and not seen this problem. 9/10 times when flea control fails it turns out to be something other than the active ingredient of the spoton, be that environmental control/ other non-treated pets/ underdosing etc

Works well here but we only tend to use it for very tiny puppies and kittens, ear mites or poss sarcoptes.

Imidocloprid still kills fleas fast but unreliable for routine use because not convinced it is robust enough to last a month. Advantage and its clones are unreliable but the best of the over the counter treatments.

We stopped using it back in 2000s(Frontline in the 90s) as Aussie fleas are tough little buggers with no winter break. Applied it for weeks in one dog, no avail, one vial of Advantage-end of problem. It was good for otodectes every 21days by 2 or scabies every 2 weeks by 3 but now its just all Bravecto and nothing else really sells any more except Avantage/Advocate for cats

+1 to Gillian, we have never used much Stronghold, and now most dogs and a lot of cats are on Bravecto.

No, haven't seen any resistance to stronghold in cats or dogs. But, to be honest, most of our dogs are already on 'Bravecto and we're gradually swapping the cats into it now.
