I would never use hartz and everyone needs to know that it does have a toxic ingredient than can kill your pet even the flea shampoos by hartz are dangerous. It is sad that they are allowed to still make this dangerous product. Oh and I hate flea and tick collars, they are disgusting and I get sick from being around them so I would never use those. Sergeants has different ingredients all together than hartz and I have not heard any animals getting sick off of it which is what I want to know. My dogs all get advange or revolution. I was just wondering if I could use sergeants flea med for my cats. |
