i'm away from home for a couple of weeks with our golden retriever who normally eats mainly a raw diet. For convenience yesterday i bought a pkt of value frozen lamb mince but when i got home noticed it is a mixture of soya and lamb. Is this ok or would i be better to cook it?

I don't think Soya is any good for dogs.

I'm sure its on the no no list.  could be wrong of course.  I'd buy the usual food and freeze it to defrost or give them a treat of tinned for variety.  Dog might like it for a week.

Have you time to swap their food over before you go?  Then swap back on return.
