Having 7 dogs myself, these a affordable and a great alternative to frontline, you wont be disappointed.
I used this on 10 dogs after seeing a flea infestation. I found it to be very easy to apply, not messy and every single sign of fleas were gone the same day and did not return.I am going to reapply now after 2 months to to on the safe side. I did use 2 flea bombs at the same time.
We had a bad flea problem with our 3 dogs in the summer. We used the most popular treatment as 'recommended' my our vet, Frontline which cost us nearly £70, but it simply did not work. Because of this we thought we would try a cheaper alternative as we were quite desperate but did not want to spend a fortune so we ordered some Fibrospot which for the same doses cost us a little over £20 for all 3 dogs. The result was excellent, in just a few days we were combing out dead fleas and within a week the flea infestation was gone. What a great purchase, I would recommend this product to anyone.
