Kudos to Doggie Mom for picking up the stray or should I say Maddie! I do hope the adoption goes through. If he jumped in the car that easily he formerly had some human contact. Probably another "Throw-away". How sad. As far as dog tags, I don't know why everyone doesn't do it. Both my dogs have two tags. One with rabies vac date, the name of the vet clinic, and an ID number; and another with their name and my phone number. The microchip would definitely help in case of theft or if the collar is removed. Tags are relatively inexpensive. They can be purchased from the vet or even at WalMart they have a machine that will inscribe a tag for something like $4.00. My dogs have never been lost but I have on at least two occasions had a dog come into my yard and I was able to call the owner because their number was on the tag.
