Hi Jennie,
Sorry to hear that you had a bad experience with our dog tags.
We use great materials and personally we inspect each dog tag before it leaves our HQ, but some times mistakes happens.
Please keep in mind that our tags are not indestructible and they are not chew proof. If your pet is a tag chewer, it's recommended you move the tag to a harness or a collar reserved for special occasions.
Our customers satisfaction is very important for us. So please send us an email to hello@upet.co and we are going to be more than ready to assist you with this issue.
