Is the result visually noticeable after using the drug?
If the animal was severely infected with helminths, then after treatment the animal's appetite and stool will become normal and the state of the fur will improve etc.
Improvements are especially noticeable in kittens and puppies – they significantly gain weight and grow, become more active and their forms become more attractive. These changes will occur only if the problems are associated with helminth infection.
If the animals are not severely infected or the drug was used for prevention, there will be no visible changes.
