There are lots of people getting their hands on several pet products and medications to sell to the loving pet owner who wants to desperately to do what is right for their pet.  Yes, the products and medications can be costly.  It does sound good to get those products that you need cheaper.

I know for a fact that Merial (the maker of Frontline Plus) does not sell to any companies or pharmacies other than veterinarians.  Now, how people aquire the products is actually unknown.  Do they purchase from over seas?  I'm sure some do.  But I do know this, if you purchase from someone other than your veterinarian, the manufacture warranty is VOID!  If your pet becomes sick because of the medication you have purchase from some other source, the manufacture will not back it.  You MAY be able to get a refund from whomever you purchased the product, but you will receive no help from the manufacture in the treatment for your pet. The use of a product off label is VOID as well.  Merial does not recommend using the product in any other way than the way you purchase it through your veterinarian.  I am a Vet Tech and I am not trying to just sell you a product.  I have treated a cat for seizuring from having flea preventative applied that was to be used for a large dog.  You will find sellers who sell large doses of canine Frontline to break down to treat several cats or smaller dogs.  These people do not work for pharmaceutical companies and can not purchase from them without federal i.d. numbers.  There is currently a new flea product on the market called Promeris.  The pharmaceutical company has ensured that this product will not hit the outside stores, internet or magazines.  They have cleverly attached a tracking code to each box.  If the box get in the hands of an unauthorized dealer, "hugh trouble".  You are only able to purchase exclusively through your veterinarian.  Ask your veterinarian what I have spoken about.

This information goes for just about any product you can think of.  From Frontline to HeartGard, Rimadyl to k9 Advantix.  Think about what you are purchasing, will it be cheaper in the long run?  Please always talk with your veterinarian before making any decisions concerning any medication for your pets.
