Both. Collar for ID tags ONLY. Harness for walking on a leash. If you're baby is young (under 18 months) you can find inexpensive harnesses at Petco/PetSmart taht will get the job done, help get the pup use to it, and not break the bank. When your pup is done growing, you can invest in something like a Buddy Belt. I personally love them. They're leather, will really mold to your baby's body, and will get buttery soft with time and use. I only have one pup, but I'm already up to 3 BB's and looking at possibly more. (I keep forgetting the harnesses and like to keep a spare in each car) I tend to suggest waiting to "upgrade" to a BB because they will set you back a few $$ (Starting at around $40). It's a shame to spend that much on a BB they will grow out of in a few months.
