We currently feed our dogs skinners ... about £20 for a 15kg sack and I believe about 26% protein (although would have to check!)
We have a border collie cross who cannot have any artificial colours or preservative due to his skin and who holds his weight well, a black lab who will eat anything you throw at him (but won't touch the other dogs bowls once his is empty!) and a Spanish Mastiff cross who we struggle to keep weight on in the winter.
Our dogs are free fed in that their bowls are refilled whenever they are empty. They are all looking very good right now and are very fit and healthy. They get the odd gutted rabbit or squirrel if my OH has been shooting and pretty much as much horse poo as they can eat
Would be interested to see if anyone has any opinions on the feed we use. I second that arden grange is a brilliant food but our collie doubles in size on it!!
In my opinion loosey, Skinners isn't too bad.
I've said before that feeding raw gutted animals is wonderful so keep that up as much as you can. Even the horse poo is good, just minging for us to watch
I wouldn't worry too much about protein levels. The amount of good quality ingredients is most important. NO derivatives.
