30 Pcs Puppy Whelping Collars Newborn Pet Collars Double-Sided Soft Adjustable ID Bands Puppy Collars for Litter Newborn Pet Dog Cat 15 Colors（M）

This is a perfect size for 3 week old Labrador puppies. We have 11 all black puppies and this helps us tell them apart.

Cheap and flimsy but they work well for short term use.

Good for a new puppy as you can cut to length and the entire collar is soft and has no hard, sticky or fabric that might hurt a tiny pup! I’ve used many times for litter puppies. Good for identifying each puppy for weighing and monitoring issues. If you have pups that all look alike but one or two might be under weight, this is a nice way to know which pup is which. My first litter I weighed them all and was super ocd and crazy about each pup, the next go around was more for just knowing quickly which pup needed longer feedings then another pup. You can cut them easily and it comes with a nice log book if you like to log everything. It’s nice to have extras as well, this pack comes with a double set and it was nice to have as a few needed replacement on pups. Super easy to use and super soft! Don’t hesitate these are perfect for new born puppies! I usually change to different collars when they become 6 weeks old with bells!

Love them they multi purpose

They're easy to trim down to a size appropriate for a kitten. Honestly I could make two collars out of one for these kids. I recommend trimming the Velcro strip in half for kittens because it's surprisingly strong. I ordered a medium because it was the smallest available. I think this is fine considering that they're easily cut to size.
