Sizing your Optivisor
A Snug Fit!
When fitting your new OPTIVISOR, make sure the neck collar is fastened firmly, otherwise your dog is less likely to accept the collar. Depending on the temperament of your dog, you may loosen the collar slightly after the OPTIVISOR has been accepted by your special friend.
Head measurement instruction
STEP 1 – LOCATE THE MID POINT
Run an imaginary line across from behind one ear all away up and across the dogs head to the back of the other ear you will find the mid-point located in the centre of this line. This mid-point is used to establish the head measurement.
STEP 2 – ESTABLISH THE HEAD MEASUREMENT
Measure from the mid-point to the tip of the dogs nose – DO NOT follow the contours of the dogs face. – Measure in a STRAIGHT LINE ONLY (you may need to lift a straight ruler away from the dogs head see below diagrams) The resulting measurement represents the head measurement, you will use to size your OPTIVIZOR using the table provided.
STEP 3: FINAL SIZING
Using the tables provided size the OPTIVIZOR by head measurement and by canine weight. You may find you have 2 different sizes according to the 2 charts. This is because, as we know, dogs come in all shapes and sizes. Simply pick the smaller size. It is always better to size down when in doubt.
Size Chart
Catered for dogs of different shapes and sizes!
Short Snouted Dogs
To determine the correct size for dogs with short snouts is difficult, as the breeds in question often have such a small snout, that we can not use the same method as for normal snouted dogs.
The good news is we have a special product just for them, the ‘short-snouted’ Optivizor. We use the head’s circumference to help indicates the best size.
Please measure the dog’s head from the top of the head between the ears (mid point), then down and around behind the jaws and back to the mid point. Measure relatively tight around the head to avoid oversizing.

Normal Snouted Dogs
To determine which is the best fit product for your dog, simply follow the sizing guide below. Please follow the directions carefully and when in doubt size down
Important note: When measuring for size, please use a straight edge and DO NOTfollow the natural curves of the dogs face, or you are likely to oversize.
Long Snouted Dogs
So, you have a whippet, or greyhound or another breed with a long snout. To determine the correct size for these dogs read the same instructions as for ‘normal snouted’ dogs, but use the reference table shown below. We will only be looking at the dogs head measurement to determine size.
There are 3 sizes available.
Important note: Remember when measuring for size, please use a straight edge andDO NOT follow the natural curves of the dogs face, or you are likely to oversize.
