Study finds only low levels of methylmercury in dog foodApril 25, 2019A study by the University of California (UC), Davis on levels of methylmercury in samplings of commercial dog food has found low concentrations in the majority of the tested brands. Only three of the 24 types of dog food tested positive for low concentrations of total mercury, and only one contained detectable methylmercury. "The concentrations detected are unlikely to pose a risk to healthy adult dogs," says lead author, Rae Sires, a nutrition resident at UC, Davis's Veterinary Medical Teaching Hospital. "These results should be reassuring to dog owners." Other studies have measured total mercury in dog food, but this is the first time testing for methylmercury has been done. As methylmercury is present in aquatic species, researchers evaluated dog food containing fish, as well as fish-free foods. They found two of the three positive samples among the non-fish diets, which suggests common sources of mercury in pet foods. "We need more data to determine where the total mercury detected in dog foods is coming from, but our study doesn't support avoiding fish or salmon-based diets," Sires says.

Talking the talk—What to say when clients prefer raw dietsMarch 21, 2019One only needs to pay attention to the news or trending items on Facebook to see the spate of pet food recalls happening in our country. And with an uptick of pet parents feeding their dogs raw or freeze-dried raw food, it is important veterinarians have honest and open conversations with their clients about concerns surrounding these diets. The following is American Veterinary Medical Association's (AVMA's) position statement on raw diets: "AVMA discourages the feeding to cats and dogs of any animal-source protein that has not first been subjected to a process to eliminate pathogens because of the risk of illness to cats and dogs, as well as humans." Katy Nelson, DVM, medical director of Pet Health for Stop Aging Now, agrees. "Cooking or pasteurization through the application of heat until the protein reaches an internal temperature adequate to destroy pathogenic organisms has been the traditional method used to eliminate pathogens in animal-source protein, although the AVMA recognizes that newer technologies and other methods, such as irradiation, are constantly being developed and implemented," Dr. Nelson says. "Most veterinarians are going to listen to the governing body of our profession, as well as the Centers for Disease Control (CDC) and …
