Advice from all welcomed please.
We have a new puppy! He's being fed Purina Puppy Chow as that's what he was fed before, but we've been advised by someone that its bad for dogs longer term because of the maize/grain content. They've advised a different brand which is mostly animal protein, egg, some oils but grain free. They also advised mixing with some mashed potato to give veggies (apparently the dog would eat the stomach contents of its prey in the wild for this?) and said that with the different food, the poo would become much smaller in amount (once a day if that) which was better for them.
So. Is this person a loon or is there a grain of truth in it? He's got an obvious bias, his shop sells the grain free feed at a suitably high price per kilo.
