>I do think that choosing and using a product that is loaded with chemicals and pesticides based on what is easy to use is pretty shocking.
What are you talking about? Drontal Puppy is extremely safe and effective and used by many hundreds of thousands of breeders, the world over. It is just as effective and safe as Panacur.
Given that they are equally effective and safe, I choose the product which is easier. Thanks for the snarky remark, though.
Different wormers suit different pups/breeds/individuals, so some will have a reaction to Panacur. Others might react to Drontal. Breeders know their lines and what their particular dogs and lines are ok with. None of that means that, overall, one is safer than the other.
Any product which has been licensed for use in the UK has been through vigorous testing procedures.
