I've been using frontline spot on for the last 3 and a bit years on my dog but I bathed and defleaed her Thursday and since then I keep finding the odd flea on her coupled with her incessant nibbling.

I'm now thinking perhaps the fleas or her are being immune to Frontline. I just wondered what everybody used?

i use advantage i get it from medic animal

I use Advantage too. My vet was punting a new one by Pfizer saying it was cheaper than the rest but as their last one was taken of the market for adverse reactions I wouldn't touch it with a barge pole.

i use advantage because i found frontline was crap and my little one is allergic to stronghold they are indoor anyway but still need treating as my neighbour has cats and i go in there daily and hers go out

I use advocate because it prevents against Lungworm aswell, nothing else does.

My vet has been using Advocate for at least the last 3-4 years. She says many cats are now resistant to Frontline. The only issue for me is the price because it costs over £90 for 3 cats for 3 months supply. I usually apply it every 6-7 weeks rather than monthly but my cats are flea free. In fact, none of my cats have ever had fleas.

The only issue with Advocate is that it isn't suitable for Collies - otherwise its brill

Ahhh yes i remember reading that somewhere the other day now, good point.

I may ring the vets and see what they recommend because she has incredibly sensitive skin. I've had to resort to giving her piriton, cod liver oil and evening primrose oil everyday because her scratching is becoming a problem. Previously after using flea treatment she settles down and hardly scratches at all but if the Frontline is no longer working she needs something else that is going to work.

How about Frontline Plus? The plus one is better and only available with a prescription. One of our cats has it and she has sensitive skin. The others have Advocate, but it's a bit strong for the sensitive cat.

can i ask why i hadnt heard of that

Another vote for Advocate.

i imagine because it contains ivermectin, or some derivative of ivermectin

which can kill collie breeds as they seem to be very sensitive for it. i have to be very careful around ours when dosing my guineas and rabbits with it not to transfer any to where he could come into contact with it.

i'm kind of thinking i've been lucky now as the vet once prescribed us advocate for our border when we asked about it
this was around the time of the initial lungworm scaremongering started

we've been using the bob martin equivalent of advantage (bob martin double action - wouldn't dare touch the other bob martin stuff) for years now and never once seen a flea on the boy

a friend just got advocate for her cats because of a really bad flea problem - frontline was completely ineffective.
the advocate began killing the fleas within 6 hours of administration.

on the plus side of that, it's also a wormer, so no forcing a tablet down their throats

As xdow says, its because it contains a derivative of ivermectin. Not all Collies are sensitive to ivermectin but those that are get a serious - potentially fatal - neurological reaction.

Its a genetic sensitivity that (so far) only collies and Collie crosses have.

thank you for all your replies - i shall have a look online later at the brands you've suggested but i think i'll pop into the vets next week and get something. i've diluted a small amount of tea tree oil with warm water to spray on her coat, i know tea tree oil is toxic to dogs but most flea shampoos contain a small amount so I'm guessing as i've diluted about 5 drops in 400ml it's not going to harm her and hopefully will help with the fleas. she's a labrador so advocate should be fine.

Slice A lemon & boil in 1 pint of water.Allow to cool & strain off the liquid.
Use the liquid to bathe the dog.Do NOT attempt to dry the dog at all

I feed a small amount of garlic to my dog and have never had to use a flea treatment on him. You have to be careful not to give dogs too much garlic though, although he's never had any trouble digesting it.

I'm very glad I googled Bob Martin flea products before deciding what I was going to use on my cat. So many reports of people's cats having fits and dying because of Bob Martin flea treatments! Couple of facebook groups with lots of people who've lost cats to it too. I don't know how they can justify not withdrawing it.

Years ago i used it on my cat, the cat went and hid under the sofa and was frothing at the mouth, i took her straight to the vets and the vet said she had a bad reaction to the Bob Martin as it is alcohol based. I have never touched a Bob Martin product again, not even grooming products, absolute trash.

Glad you got her to the vet in time Swinetown. I lost one of mine to Nuvan Top years ago.

From what I've read online it's a good idea to wash the product off as soon as you notice an adverse reaction and then head for the vet.
