Be sure to measure your pup with soft measuring tape around the biggest part of head along (in front of the ears) with the neck measurement for a perfect fit. These are not adjustable as they are made specifically to slip on and off. We will go with the bigger measurement out of the two to ensure a perfect fit.

These silicone beads are more rubbery than regular silicone due to the glow powder that has been mixed in with the beads when being made. Like most silicone beads dirt and hair can stick to them but they can eaily be washed as they are waterproof.  While these are waterproof they are not chew proof as they are silicone.
