same food, different flavour

[karendorman13]

My 8 week old pup in on pro plan chicken and rice and would like to get him the salmon and lamb flavours, so he has some variety. I know if you are completey changing brands of food to do it slowly, but as it is the same brand would it be OK just to give him some straight away.

I always have and been fine. I think as  you say if its a different brand then do it gradual, but same brand different flavour should be fine.
