One major reason why someone would get a tattoo of their pet is if they lost the pet. A pet tattoo is great way to honor their memory whiles keeping them close as a part of you forever.
Although they are animals, pets can become a very important part of your life when you keep one. You take care of them, train them and bond with them as you watch them grow. They become your companion and a part of your family.
So the death of a pet can be very heartbreaking and it is normal to want to get a tattoo of them. This is a reminder of how much they meant to you and how much you loved them.
