CHECKLIST FOR USING FRONTLINE SPOT ON:
- Your dog is at least eight weeks old
- Your dog weighs at least 2kg
- Your dog shows no signs of lesions or feeling unwell. If they show any of these signs, you should not apply the product and see a veterinary surgeon
No flea product can stop fleas jumping onto your pets. It is normal to see a few fleas on your pet after treatment as new fleas continue to hatch out from infested environments. These fleas will be killed within 24 hours of jumping onto your treated pet.

As veterinary experts we are pet lovers like you. We're committed to keeping your four-legged friend happy and healthy with our range of products and professional advice.
HOW TO WEIGH YOUR DOG SAFELY
If you can lift your dog without risking injuring yourself, then first weigh yourself on your bathroom scales, then set the scales to zero and stand on them holding your dog to work out your dog's weight; or weigh yourself holding your dog and subtract your own weight. Alternatively ask for a weight check for your dog at your veterinary practice or local pet shop.

*For dogs over 60kg, apply two Large Dog pipettes.

I followed the instructions but she still carried on itching, I kept using the flea comb on her and even a week later there were still live fleas on her.
I went to the vets and got Advocate (prescription treatment) which worked and killed the fleas within 24 hours.
I wouldn’t buy Frontline again, either the formula has changed or fleas have evolved, either way I’d spend a few pounds more and get vet prescribed flea and tick treatment.
I don’t use every six weeks, just as and when because I don’t like putting strong chemicals on my dogs. On this occasion I had to put two different sets of chemicals on her because the Frontline did not work.

Great stuff, it works a treat and is essential for ticks in a rural area like this.

Great stuff, it works a treat and is essential for ticks in a rural area like this.

After purchasing some cans of Indorex we got it under control.
Will definitely be looking after other cat and dog flea treatments after we have used these up.
Do not waste time and money on frontline!!!!!!
I would give no stars but amazon won’t let me......
Our lurcher is into smelling all manner of scents and has had a series of three ticks attach themselves to her ears. The first two ticks each dropped off after two, maybe three days without any attention from us. The third tick was noticed a couple of days before our dog was due at the vets for her annual injection and check-up and while the vet actually took the tick out, the tick failed to grow into a normal bloated body but stayed thin and looked more like a splinter of wood and was clearly on its way before the vet intervened.
