Tattoos are not just for the bipeds anymore. Veterinarians have been tattooing livestock for years to prevent theft. but some vets are taking tattooing to new levels. For instance, take Dr. Jacque Rosholm of Main Street Animal Clinic in Payson, Arizona. She routinely gives animals ear tattoos to ensure proper identification to protect against theft and animal testing. By inking both ears, implanting a coded microchip and then inking the codes from the chip onto the animal's groin area, Dr. Rosholm can give pet owners an extra sense of security when it comes to their beloved four legged friends. Another use for tattoos is cancer prevention. At high altitudes or areas like Arizona where the sun shines a majority of the time, vets are able to tattoo the lighter skin areas such as a dog's nose. By giving the dog a layer of ink protection, the odds of skin cancer decrease significantly. Although it sounds a trifle extreme, it is a fabulous display of love as to just how far pet owners are willing to go for their animals.
