How to apply correctly

OPTIVIZOR - how to apply correctly

First of all: Dogs' heads are so many and so different that each mask should actually be produced individually. Because that would be neither feasible nor affordable, Provizor has a different approach: There are three basic models (OPTIVIZOR for short, normal and long snout) and they are designed so that they can be adapted to the maximum. So please don't expect a mask to immediately have a perfect fit - this will only sometimes be the case. Here we give some fitting advice. We gladly advise you by phone, too.  For this, send us 3-4 photos of your dog with mask (from different perspectives) to We are reachable from 9am  to 10 pm, on sundays and public holidays from 11 am to 6 pm 

Even animals want to understand! ... and none other than us pet owners know better how well they do! However, we sometimes forget to explain something new to them - yes, just with our language like with a child!
So it happens, for example, time and again that the dogs of our customers get the OPTIVIZOR fitted without comment - after surgery or during the fitting; and often the logical reaction is: defense! A dog that wakes up from anesthetic is in pain, and in case wearing the mask on his head for the first time then, concludes quite clearly: "The new mask is to be blamed for my new pain - so tear it off and the pain will stop!" This objective he will follow for several days ..... especially when the dog also is blind and does not see what happens. Therefore:
- Before the first fitting, please let the dog sniff extensively and let him rub his face against it; - Tell it why the mask is good!
- Blind dogs: One imagines intensively  the dog with a mask on its head 
- Put the mask into the dog's basket, so that he gets used to the idea
- Repeat the above and then only start fitting the OPTIVIZOR
- Praise the dog and tell him how smart he looks
- Try to have the dog see itself in the mirror wearing the mask - but do not force him!
- Always tell a blind dog what you're doing!
And do not forget: Give him his favorite treats as a reward for his cooperation!


IMPORTANT! When fitting the mask on the dog for the first time, make sure the mask is closed tight enough around the neck so the dog can not slip it off to the front! Because if he succeeds once, he will try it again and again ....




Other important hints: 

How to shorten the mask for normal snouted dogs: 

- Wearing his OPTIVIZOR make the dog lie down on its belly and have it put the head on or between the paws 
- You can now see where the mask has to be shortened: The mask should end at the beginning of the nose - that is, where the nose ends and fur begins (in this photo: cutting the innermost pre-punched ring) 

Important: An unshortened mask often rests on the nose tip - which blocks ventilation and can lead to undesirable fogging. If fogging is unavoidable, we recommend the use of anti-fog sprays of Zeiss or similar.




Side strips: 

The side strips have to be put through at least TWO of the existing slots (and thereby should end at the OUTSIDE; on the photo it ends inside, just to make the slot visible!) 
You should "weave" the side strip through the slots, when the mask is very heavily used by your dog. 





Neck closure:

From the first fitting onwards, make sure the OPTIVIZOR  is tight enough around the neck, so it can not be stripped forward over the head. This is especially important because otherwise the dog will try it again to strip it after a first success.However,  in some breeds the neck is as thick as the head. In that case attach the mask  with a plain band on the collar or harness of the dog. Since this problem is particularly in dogs with short snouts, the short snouted OPTIVIZORs have two holes in the neck region of the mask through which the tape can be pulled.


Chin closure:

In case the velcro under the chin is too short (i.e. because the dog has particularly large lips; or if the mask for normal snout like for Bulldogs is applied), replace the velcro with a standard string slung through the eyelets and close it . The chin buckle should not sit tight, it only serves to keep the mask in the correct fit.
Adjusting the mask for dogs with short snouts: 
1. nose bridge 
Remove the nose bridge and adjust the edge of the mask if necessary by slight shortening if 
- The dog has no nose 
- The nose bridge is too large for the respective nose 
- The dog feels the nose bridge as a nuisance 




2. Shorten normal mask for dhort snouted dog
For dogs with short snout, on which the model shown above does not fit, the normal snouted mask can be used; the front has to be shortened quite heavily (see dotted line) but still protects the eyes reliably. But beware: DO NOT shorten it to the tip of the nose, as that results in too much space between the nose and the mask edge and the eyes during are no longer sufficiently protected when the dog is sniffing in the gras or bushes!

Cleaning the OPTIVIZOR: 

Scratches on the PVC are unavoidable unfortunately: A soft, flexible material is needed, which can not hurt the dog, as the mask is very close to the face and the edges are in the face and eye area. A mask worn at night may not be r to disturb the dog as little as possible. 
Consequently, touches and scratches that would otherwise have ended up in the face and eye, now left their mark on the mask. Depending on how dynamic a dog is, there are a lot or very few scratches. 
Continuous use of the mask very quickly results in a fine, oily film on the PVC, resulting from the contact with the skin and the breath of the dog. You can clean the mask easily with a soft cloth and warm water with a little washing up liquid - it will become significantly "clearer".
