• -It's recommended to have your dog microchipped. If your dog is lost and found by someone, they can have the dog scanned at the local vet's office or animal shelter. 
• -Slip leads can be good with a separate collar with identification on it.

 (this one doesn't always work for very young puppies because the gaps are too wide. This pen is GREAT for older puppies/adults because they usually can't climb over them since there are no horizontal bars.
