We pick up our puppy next week. Just making sure we have everything ready for him coming. From the breeder should we receive anything other than KC registration paper, puppy pack etc? Is it best to give the puppy the same food that they've been eating for a few weeks before changing it? As for worming tablets.....is it best to have the same brand that they've been given and how often should they keep recieving them? Flea/tic treatment, should I put that on the day we collect him?
