Easiest way I know to help insure you get your dog back, should he become lost. There is very little chance, if the dog has no tag. I have the stainless, and it is very durable, and holds up well.

Pros: Durable

Cons: None

this is an excellent grade product and the warranty is the best...more than I expected

Pros: all

Cons: none

Only needs to be changed if you move and it only takes 24 hours.

Pros: stainless steel, tough, never have to change

Cons: none

I went to this style tag after the plastic one broke. It has lasted a long time and easily fits all my contact info.

Pros: durable

Cons: n/a

The size of this tag is great and you can get one at your local pet store and have it personalized. I was able to include 4 lines including Pet's name, address and 2 phone numbers (home and cell). My dog has had his for several years and it has held up well. It is important to check it from time to time as I have seen dogs wearing tags but the engraving is no longer visible.

Pros: Good size

Cons: engraving can wear off
