Some of the best places to compare dog food brands, such as Victor, with other brands are dogfoodadvisor.com and dogfoodchat.com. Both of these sites feature active message boards where pet owners can share advice and ideas.
Dogfoodadvisor.com gives extremely detailed descriptions of nearly every brand available, and it rates each food using a five-star scale. This site breaks down the ingredients in each food one by one and explains the risks and benefits of each. It also features a dog food calculator, which uses a dog's weight and activity level to determine how much food that dog should eat in one serving.
