A SPECIAL PUPPY WELCOME
Upon arrival give each guest a pair of their own dog ears.
You can make these by attaching felt ears to an inexpensive painter cap from a paint or hardware store. Enlist a teenage or adult helper to face paint a simple nose and whiskers on each child. 
Invite the children to draw and decorate the "Dog House", with markers,
while they are waiting for all of the guests to arrive and receive their face painting. This activity is also effective for settling the children down at the end of the party - parents will really appreciate the thought!

PUPPY OR DOG PARTY GAME IDEAS
Have a dog biscuit scavenger hunt. Write numbers on the bones before
  hiding, then the children will receive a prize that corresponds to the
  number on their bone.
Water bowl relay races with real dog bowls
Tug of War
Puppy challenge obstacle course
Pin the tail on the puppy
Play "Dog, Dog, Cat" instead of Duck, Duck Goose.
Feed the Dog Bean Bag Toss
  Make a large drawing of a dog. Place it on an open cardboard box,
  or laundry basket. Provide a few bean bags and the children will
  take turns trying to get the bean bags into the box.
Puppy Match: Before the party print out some large pictures of dogs in 
  varying breeds. Cut the pictures in half. Then hide them. Each child will find
  one half of a picture. They then need to find the player who has the other
  half that matches their dog breed.
Provide a few puppy coloring books/sheets and crayons for a quiet activity.
