This Who Rescued Who Necklace is adorable! Chain goes right thru the center of the circular pendant.  Pendant is about 1.18" in diameter & hangs from an 18" chain.  It is made of lead free, nickel free & cadium free zinc alloy. Most times when we rescue a dog, we don't even realize how much they end up rescuing us!  They show unconditional love and fill a place in our hearts that we did not even know was empty. If you know someone who rescued a dog, then you know someone who will adore this necklace! If you rescued a dog, you will love this necklace!
