What the tag is for
It lets anyone who finds or is bitten by your pet trace it back to a vaccination record through the clinic or county that issued the tag. That is its job, and it matters. It just does not carry the details someone checking your pet needs.
What people checking actually need
- The date the vaccine was given, and the date it is next due.
- Which animal it was given to.
- The product and lot, and the vet’s name, license and signature.
All of that is on the certificate, none of it is on the tag. Tags are also often a year or two out of date, because nobody swaps them.
Keep the tag on. Keep the certificate close.
Leave the tag on the collar and keep a photo of the certificate on your phone. If you do not have the certificate, get a copy from the clinic.
