The spray is not harmful. The burst of spray distracts or interrupts your dog's pattern of behaviour. Spray is available in citronella scent or unscented refill cans. Some dogs find one scent to be slightly more unpleasant than another and this can make fast training at times or you, as the owner, may have a preference. Regardless of the scent, the spray dissipates quickly and is safe for humans and pets.
Be sure that the collar and remote are correctly charged and/or have batteries with enough charge.
Make sure there is enough spray in the collar.
If your collar is equipped with a counter (Spray Trainer), check if it needs to be reset.
If you have not used the system for a longer period, sometimes the spray can dry in the outlet valve. To resolve this, hold the collar under warm water (max. 35-40 degrees Celsius) for a few minutes. This should make the spray fluid again. Dry thoroughly afterwards.
Sometimes air can get trapped in the collar, which will impede the spray to make enough pressure to come out, or the air can be blocking the outlet valve. To remove trapped air:
Empty the collar of all spray by pressing down into the spray inlet-valve (where you would normally fill it) with a small screwdriver or old pen. Keep your face away from the spray and watch for the small black washer, as it can sometimes fall out.
All of the spray should now come out. Continue to press until empty. It should take 5-15 seconds to release any air blocked inside.
Give the collar a couple of taps on a hard surface to mix everything. Press again with a small screwdriver in case there is anything left.
Refill the collar. Turn it on and test again.
For the SSSCat™ Spray Deterrent Kit: Turn the unit off. Remove the motion detector from the refill can. Turn on the device. Wait 30 seconds. Pass your hand in front of the device. If you hear a click, put the motion detector back in the can. Then if it still won’t work, contact the Customer Care Centre for a replacement.
