My favourite is Golden Eagle Salmon formula on plus supermarket food mix.  I get mine from Pet Lovers Centre.

The Dog Whisperer episodes shown now on hyppTV are 2009 to 2010.  Caesar already used positive reinforcement on selected dogs only.  His critics who are not employed by any tv station mostly say it is wrong to use threadmill, wrong to put dog in even big cage, wrong to tug the dog leash a dog to correct it, cruel to kick a dog lightly to the side to snap dogs aggression, wrong to walk a dog less than 1 hour a day and cruel to show who is the boss to the dog.
