Hi, we have just got our first cocker puppy, he is almost 10 weeks and fed on Purina Pro Plan soaked in water, he dosen't really seem to relish his food, gradually eating it, so I tried mashing a teaspoon full of Butchers puppy food in the foil container in to tempt him, this works but his poos are a little softer since I've done this, am I right to do this ? also he sometimes eats his poo if I'm not quick enough to scoop, Is this to do with what he's eating ? TIA
