These are the smallest collars I have made to date. This one pictured fits 5-7" necks and is 1/2" wide.
These would work nicely for younger puppies or micro-dogs like Chihuahua's or Yorkies.
At the moment, the only trims available on these are the grosgrain ribbons. Most of the jacquards are too thick and once sewn onto the webbing they will not fit through the hardware. Don't worry, there are more polk-a-dot grosgrain ribbons on order and I'm scoping a few sources for some nice striped and printed grosgrain.
Once the new ribbon arrives I will be making breeder puppy packs to make identification of those cute little bundles of fur easier.
