interesting reads, although like everything must be interpreted. The first article had to do with know carcinogens in humans. Probably the same as in dogs, but what quantity is needed to be an issue. A tablespoon a day? I doubt it. The second article might be more interesting if it wasn't written by someone who has something to gain by saying what he is saying. He is a promoter of health foods for dogs. Does he have an agenda, I say yes. He is also a proponent of feeding dogs raw meat. I have actually at one point thought about this so I have done a little research on the idea. A very respected vet I know advised against it. Yes, he admitted it could be good for some dogs, but there are a number of dogs that will develop permanent or long last irritable bowel syndrome. This is a condition I don't want any of my dogs to get. So everyone who has a good idea, there are side effects to each of them. I don't have any fat or overweight dogs, but if i did I would watch what they eat. I actually monitor my dogs weight very closely to make sure they are not loosing to much or gaining to much weight. During the height of the hunting season I make sure they are not dropping weight, and actually prefer them to put on 2-4 pounds. In the off season sure they stay at 51 to 53 pounds each. That is their ideal weight.
