I used to recommend Innova all the time but won't anymore. It has garlic in it which I thought was just fine in small amounts. I have recently read that even small amounts of garlic given over a period of time can cause dermatitis, asthmatic attacks and anemia. It seems that it isn't always larger amounts that cause it and nobody can predict the dogs this will happen to. Hemolytic anemia is extremely serious. It isn't worth the risk to me.
