So, I have a very confident dog...he literally prances when he walks...he has no shortage of self esteem- which I could learn from!  So, it is only natural that when I clip my new design on his collar, he knows he looks goooooodddd.  We love to adorn ourselves with beautiful jewelry and we love crystals that make us feel amazing.  I don't think there is any difference for our furry companions.  
Introducing...."Poochie Pendants."  These clips go right on your pup's collar. It is also interchangeable as a keychain for your keys.  I have personally stamped the metal heart with a dog paw, and on the other side I have inscribed the symbols for "peace, love, and happiness"- because that is what our dogs give us, and what we want to give back to them!  
This particular Poochie Pendant comes in "Amethyst" which is an excellent tool to combat anxiety...perhaps when you go to the store for a few hours?
