I feed raw whenever I can but as the convenient alternative I use Butchers Tripe. It's £1.25 to £1.35 for a 1200g can and that's enough for 3 days for an adult Springer with a corresponding amount of mixer. In my lot there is one greedy one, one that has to be tempted to eat and one that just gets on quietly with eating and they are all fine with this.

I think the suggestion to ask for samples is a good one but don't make too many changes trying them out if your little one has a sensitive tummy.
