Reflective Underground Fence Collar
What size Underground Fence Collar should my dog wear?
Medium Dogs - Collar length 9"- 31" 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.
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”
The Invisible Fence brand recommends the collar be snug enough to slide only one finger between a correction post and your pet’s skin. Remember to adjust the fit of the collar as your pet’s coat, weight, and age change.
Please Note: Collars have two heat-sealed holes for DogWatch® systems or, three heat-sealed holes to fit all Invisible Fence Brand® receiver models as well as Pet Stop®, Pet Safe® and Dog Guard® systems.
