Lightweight Round Shaped Medical Identification Disc. Important information regarding your pet's health or temperament can be engraved on the back of these discs. If your pet already wears an identification disc, these medical discs can also include your Vet's phone number. Engraving examples: "I am deaf", "I need heart medication, Vet Ph 8xxx-xxxx", "I have Epilepsy, Need daily medication", "I do not like Men", "I'm Very Timid". Knowing some of these things can help the professionals at the Animal Shelters, Councils and Vet Clinics to care for your pet if they happen to go missing, until they can be reunited with you. Size 31mm. Size best suited for Medium to Extra Large Dogs. Comes with Split Ring attached. $5 will be donated to the AWL or Fairview Lodge Animal Rescue for every disc sold. Please select which charity you would like to receive the donation.
