To
measure your dog for a
Martingale Collar, use a soft
tape measure or a piece of
string and take the measurements
at point A, B, and C in the
drawing below. Choose the size
that fits within this range to
ensure that your collar fits
perfectly.
For Sight Hounds,
the measurement at points A and
B may be the same or very
similar, this is because their
heads are often the same size or
smaller than their necks. For
non-Sight Hounds, these
measurements will be different
and you will need to choose a
collar size that is large enough
to slip over the head (point A)
but not too large to fit
correctly at point B.
In other words,
choose the smallest size that
will still fit your dog. If
your dog has a 15 inch neck,
choose the Medium, which is
adjustable from 13-18 inches
rather than the Large, which is
adjustable from 15-20 inches.
