A well-engraved tag isn't any good if it doesn't stay on the dog.
The tag itself is about the size of a five cent coin. The online photos show the loop on the tag is as thick as the tag itself.....wrong! It is about 1/3 as thick and the tag broke off at the loop after only 3 days on my dog's collar. I found it on the bedroom floor. My 9 year old pointer isn't real active anymore, so it wasn't playing rough that broke it. My guess was him scratching an itch. A well-engraved tag isn't any good if it doesn't stay on the dog.
