After I posted that Vioxx and Heartguard were owned by the same company, I received a very nice e-mail informing me that I was not correct. My original information came from my vets office, the correction came from a lister. << Please correct the misinformation that you posted. Heartgard is made by Merial. Vioxx is made by Merck. Two different companies. >> Without trying to search on companies, subsidiaries, and brands, I'm posting the correction I received. I received it nicely so apologies to whomever is right or wrong.
