Our 5 month working cocker is currently on CSJ little champ not sure if people recommend it or not but she loves it, I was just wondering does anyone recommend and add things like fish oil supplements to their dry food?
I'm guessing you are in the UK? Labeling requirements are different, and I'm used to reading US labels, but it looks like a perfectly decent food on paper. If she likes it and is doing well on it (nice skin and coat, good poops, and plenty of energy), then I see no reason not to feed it. Fish oil is okay for adult dogs, but not something I'd recommend for a puppy. If she doesn't seem to be doing well on this food, try something else to see if it works better.
