Yes, they're very cute and in all likelihood harmless.
Yes, they were in your yard (at least that's where they started out) and there were people with them.
However...
There are other people in the neighborhood (like me) who enjoy walking their own dogs (as I do) and those dogs are just this side of puppy and are still learning their manners (hence the walking, on a leash, with a very short lead for control even).
All of the above is not license to allow your very small, very cute, and obviously very untrained puppy to go charging at my (much larger) puppy. See, my (much larger) puppy sees it as an invitation to play, which results in my having to hold her back while your obviously very untrained puppy goes tearing around your yard and neighbors' yards and the (thankfully quiet) street, in frenzied exuberance. Now if you were familiar with my puppy, I might let her have a longer lead and allow to her play, as she so desperately wants to, because she is the friendliest soul on the planet and hasn't ever met a doggie or human she doesn't want to play with. However, since you're not familiar with my puppy, all you see is seventy pounds of large black dog desperately wanting to get at your (obviously untrained, since she ignores your calls and seems to think that your running towards her is some new! fun! game! that gives her permission to run ever further afield) puppy.
Thankfully, I am a rather strong individual (plus, short leash and walking harness and all that) and I've been working on my puppy's manners, so after the initial burst of excitement, she heeded the command to sit and waited patiently as you chased your small (and yes, very cute and I'd hate to see anything happen to her) puppy across three yards and the street, I'm sure hoping the entire time, that a car wouldn't round the bend.
Just a word of advice—if she's that bad about listening, keep her on a lead when you're in an unfenced front yard where any manner of cars, people, and yes, other large dogs might be passing by. Just because she's small, doesn't mean you shouldn't take the same responsibilities that those of us with large black dogs do. In the end, it makes everyone's life so much more pleasant.
No love,
Me.
