Sizing Muttluks Accessories
How do I measure my dog for accessories?
For MuTTuque, measure the circumference of the neck (A) and the head (B).
Use the larger measurement when matching to the sizing chart.
For KoziNek, MuTTravel ViziNek, and MuTTravel ComfiNek Collar with AirTag Case,
measure the circumference of the neck (A) only.
Step 1: Measure the neck (and head if applicable)

Step 2: Match to our sizing chart
Choose the size where your measurement falls comfortably within the range. If your dog is between sizes, select the larger size.
