They don't remind me of dog tracks either, by the say you some of them together. I'm thinking like Indiana Karen, either a rabbit, or a squirell, looks like something that kind of hops as it runs or goes. Perhaps it was a small dog running around. I have a big old lab, and from this angle it don't look like my dogs prints.
I can see you now, all bundled up and following the tracks...
I hope whatever it is, doesn't end up falling through the ice.
