The Bulldog Information Library has great information pertaining to Selecting a Puppy with Personality Tests...
when we went to choose a puppy , we did so with our family in mind and how the puppy would best fit into our family..that way we could give it a head start on fitting in with our children,home, and lifestyle..or your own personality ! Make sure you are able to become the alpha leader that he/she will need,although there can only be one alpha in a pack (your family ) there is a totem pole , you will decide where he/she will rank! and dont worry ,, you will have a good amount of time together to establish this but it will make it a lot easier on you if you can decipher the personality of the puppy before you buy it ! We chose a C personality , we have small children and wanted to ensure that the dog we chose would not shy away or bring about anxiety problems later on when the little ones approach him. Of course personality traits vary from breed to breed so Im sure you are already read up on all of it, haha, we checked out EVERY Ceaser Millan book our library offered and had some sent in. ! We also went on choosing a male. Of course this is preference, our boy (Samson ) has been AMAZING he is great with the children, not aggressive, (you can be in charge of keeping this in check as he/she grows )pretty much what we expected from personality test.
Best of luck with your puppy !and have fun training ! (have fun training your puppy too) It took Samson to show me how to become more assertive and a better leader !Enjoy your baby ,,whatever you decide on !
