Fully adjustable harness, healthy Y type, fully padded. Three leash attachment points.
To determine the correct harness size, you must measure your dog in 4 places:
A - B dimension: from withers to sternum (not to be confused with neck circumference)
Dimension A - D: the back from the withers to where the string is tied
Dimension B-C: lower part from sternum to where the string is tied
Dimension D - C - D : circumference of the chest.
Using a string or leash, tie it to the dog at the widest point of the chest. Then measure the circumference around the string. Leave the string tied for the next measurement.
