This product uses Fipronil as its active ingredient, which is effective in killing fleas within 24 hours and ticks within 48 hours. Additionally, it prevents flea eggs from hatching, which reduces the risk of future infestations. Suitable for large dogs weighing between 20-40 kg, it is safe to use on pets from 8 weeks of age, making it ideal for growing puppies as well.

However, there are some drawbacks to consider. While the product has a strong safety profile, as with most chemical treatments, there may be side effects in some dogs, such as skin irritation. Another potential downside is the limitation on delivery, which could restrict availability outside mainland UK.
