ID tags are a must for every dog. If you don't have a license, at least have an ID tag for your pet. If your pet ever accidentally runs away this is a great way for a good samaritan or shelter to find the owner. My dog has a gold bone shaped one.

Pros: Different shapes, colors, sizes

Cons: none

Everyone needs to have an id on their pets!! Although my dogs were able to some how get these off and I had to find a stronger way to attach them to their collars. I used the ring of a key chain holder instead of the flimsy one they came with.

Pros: Helps return lost pets.

Cons: Not strong enough for my pets!

I personally think this is something great for my dog to wear in case he gets lost since all of his information would be on the tag =]

Pros: Works great in case your dog gets loose

Cons: none

To not have a tag on your pets would be very irresponsible. This is a good one to use, because it is easy to read and inexpensive

Pros: easy to use, get your pets home

Cons: none

very good to have these. Important for your pet to be identified

Pros: important

Cons: ?
