As I said I feed a variety, but Chappie isn't something I'd feed as I looked at the ingredients.
I buy a lot of our food on Bitiba, which is the discounted sister site of Zooplus. Rocco Classic is the example I was referring to. 75% rating on allaboutdogfood. It's made of 70% meat , 28.8% broth, with minerals and linseed oil making up the remaining 1.2%.
No food is perfect and we use more expensive/ higher rated foods too but have to balance the cost when feeding 3 dogs, so use a variety as they all have different tastes and get bored easily.
I think it's important to look at the ingredients and see what your dog's food is made from, especially if your dog has allergies or intolerances. Cereals and chicken seem to cause high rates of allergies/ intolerances, including in my dogs.
Chappie is mostly unlisted cereals with the second ingredient as just 14% fish and derivatives and 4% chicken and derivatives. Not what I personally want to feed my dogs. Although for dogs without allergies to these ingredients, I can see that it is probably easy to digest and could settle a bout of colitis in the short term.
I'm not knocking cheaper foods at all. Sainsbury's Hypoallergenic Lamb dried dog food is a regular buy as our dogs love it. It is 60% lamb, contains no cereals and is £6.90 for 2kg.
