I don't know if the product is good or not, but I find the sale misleading.... It is not mentioned anywhere on the page with the description or in the features that it is 1 tablet per 5kg of body weight... When you have a dog weighing 65 kg, you need to give 13 tablets... How long will a package costing 41.50 euros last me? I should have had the option to give 13 tablets daily or switch to another product with fewer tablets per dose...... For this reason alone, 1 star is too much... Essentially, I should return the product, but my kids opened it.. Please try to be more responsible... Merry Christmas!
