1) Measure
length of pet's back from
the base of the neck to
the base of the tail.
If the measurement
is between sizes, we recommend
going up one size.
2) Measure your pet's neck circumference.
3) Measure the broadest part of your pet's neck
Also, if pet has a stout
build, a deep chest, or
is overweight, we recommend
going up a minimum of one
size for proper fit.
If
the dog is long-backed,
like a Dachshund, a smaller
size is recommended.
