Sometimes it's suggested to find a neutral vet and ask to meet breeder there and have a vet look over the puppy before taking the final step to ensure it's in tip-top condition. It may be a small cost to you but the benefit of knowing before you take a puppy on that it is in a healthy condition, is well worth the cost.
Lastly, before you pick up and take your puppy home, it is always better to be prepared so an earlier visit to a few local vets to find the one you are most comfortable with is recommended.
Also talk to your local pet specialty store and they can assist you in making sure you have prepared for the arrival with help on your puppies diet, bedding, training, water and food bowls, flea and worm treatment etc. Also investigate puppy classes to get them and you off to an ideal start to puppy life. Day cares are a possibility if you plan to be away from your puppy during the week which will also help with socialisation.
Finally, ensure your property is well-fenced and puppy-proofed to ensure optimal safety of your puppy. You should now be well-prepared to bring a new puppy home and start the wonderful journey of raising and enjoying your new friend.
