LupinePet Fi Collar Basic Solid Colors
How do I choose a width?
What size collar should my dog wear?
Small Dogs - Collar lengths 6"-16" by 1/2" - Best for dogs under 20 lbs.
Medium Dogs - Collar length 9"-25" by 3/4" wide
Large Dogs - Collar length 12"-31" by 1" wide
The most accurate way to choose the correct size range is to measure your dog - but don't worry, it's quick and easy!
A fabric dressmaker's tape measure is easiest and most accurate. Or, a piece of string can also be used and then measured.
Measure the dog's neck comfortably snug against
the fur. Take the actual measurement and add 5% to determine the best size range.
Example: Actual measurement is 20" + 5% = 21"
