we have just got our 8 week old pup and the breeder was feeding her pedigree chum we are slowly going to introduce her to nature diet but in the meantime roughly how much of the tinned food should she be having.
             many thanks lorraine

You breeder should proved the best guide, I would keep the pup on the same amount that the breeder had her on for now. You can gradually introduce the nature diet into the pups diet over the next week or so :)

Are you sure it was tinned chum or the complete food?

The breeder of your pup should have given you a diet sheet with rough idea of amounts to feed etc.
Also on the tins or the bags of complete they do also give you an idea of the amount to feed.
BUT it is important to remember that these are only guidelines as some dogs/pups need more
and some less.

When changing the food remember to do it slowly over a 1-2 week period by slowly increasing the ratio of new food and decreasing the ratio of the old food and it can help to put a teaspoon of natural live yoghurt with each feed.
It is also important to note that young pups can find moving to their new home very stressful so it might not be a good idea to change their diet over too quickly, let them adjust to their new surroundings first.

Hope you have lots of fun with your new puppy and remember you can never start training too early
What you put in with regard to training now you will reap the rewards when they are adults :)
