If you own a dog- put identification on it!!! I am always coming across dogs that have gotten loose somehow. They almost always have collars on but no identification. An ID tag costs less than $5. As a dog lover whenever I come across a loose dog I try to catch it so it can be returned to its owner. If the dog has no ID it can be impossible to bring the dog home. I then have the choice of setting it loose hoping it finds its way home without getting hit by a car or calling animal services to come pick it up. On my ride today I came across two separate dogs running loose on busy streets with no ID. All I could do was chase them away from the road so they wouldn't get smashed. A few bucks for a tag is much less than the vet bills for a dog hit by a car or what animal control charges to give you your dog back. A rabies tag is not identification, so don't think that is enuf to have on your pet.
