This question is asked second to which sex is best!  I thought I would answer that question right here on the site for those considering adopting two puppies.  :

Two puppies can keep each other company during the day, which means less destructive behavior while you are away.  Not to mention, they don't get lonely.  It is a fact, that if you bring home two puppies at the same time, they will be bonded and you won't have the integration issues you find when adding a puppy to your family at a later date.  Usually older dogs don't warm to new additions as easily as a puppy.  It can take weeks to months for the new addition to be accepted.  So if you are considering having two dogs, why not adopt them both at the same time? 

Here are some more pros about adopting two puppies:

• Two dogs keep each other entertained and exercised---they are less likely to exhibit destructive behavior due to boredom, such as chewing furniture
  
• The first day in their new home is a breeze, as they don't experience any separation anxiety---they brought their litter mate with them!
• Save half the price on shipping, the pups can ship together and experience virtually no travel related stress
  
• We hear from our families that its easier to train the puppies because they burn off all that playful energy with each other and are more focused when they are with their humans.  Making a calmer easier going companion.
  
• Dogs housed together have a companion, and are less likely to develop weight issues, they play!
• No need for a large yard or house, our dogs are the perfect size for smaller houses!
• The extra dog doesn't require much more work than just having one, and they learn together. 
• They provide social and mental stimulation---not to mention they are a blast to watch! 
• Dogs will live longer and remain youthful and playful with positive interaction with a house-mate.

• We feel in the case of dogs--two is better than one!

FACT: An anti cruelty law was passed in Switzerland requiring citizens purchasing dogs and cats to buy two, instead of one.  They realize the importance of stimulation for these animals, maybe we should too. 

We are more than happy to help you choose the best two puppies for your family.  We do personality and temperament testing, too!
