The most common reason for this is that the yellow plastic guider on the Canny Collar nose band is not positioned under your dog's chin. Ensure that you have pulled the nose band through the guider and that your dog doesn't have a piece of yellow plastic on the side of his face (or on top of his head!).
Another possible reason is walking with too long a lead. The key to keeping the nose band on your dog is twofold: keep your lead short (but still loose) and your dog’s head upright. Try beginning your walk with the pressure applied on the Canny Collar and then slackening off the lead just enough so that the lead clip either just rests on the back of your dog’s neck or that the nose band of the Canny Collar is loose enough for your dog to open his mouth.
This means the Canny Collar is loose and comfortable on your dog but that there is not enough nose band for it to move towards the end of your dog’s nose and fall off the end. We don’t recommend using a flexi lead with the Canny Collar for precisely this reason as it allows too much lead with the possibility that the nose band will then come off the nose.
To keep the head upright, you will need to watch your dog for the first couple of minutes of your walk so that if his head drops, you can gently correct him by easing his head up off the floor with a steady upward action on the lead. As soon as his head is upright, give him plenty of vocal praise and slacken the lead once again. Don’t say anything negative to correct him if he drops his head again, just lift his head and then praise him when it is upright – this lets the Canny Collar do any corrective work (as it does with stopping the pulling) and you can then give the vocal praise reward.
Much the same as you expect certain behaviour from your dog when he on lead (ie. not pulling you), the same applies to other things like stopping to mark territory, pulling towards other dogs etc. You should be in control of your dog’s walk and not your dog, which means you decide (perhaps with a special training command such as ‘free!’) when your dog is able to do as they please, for example when your stop to let him off lead, meet other dogs, stop for a sniff etc. The first couple of minutes of your walk are the most important and set the tone for the rest of the outing.
After a few times of beginning the walk this way, your dog should start to become accustomed to you being in control of the walk and keep his head upright with no pulling. It doesn’t mean that he can’t stop and sniff etc, the only difference is that this happens when you decide and not your dog. The key to walking your dog well on a lead is consistency and if we are trying to gain your dog’s respect for your authority when lead training, he will get mixed messages if we are trying to control one aspect of the walk (the pulling) but allowing him to do the other things that often impede a pleasurable walk.
The nose band on the Canny Collar is designed to be free-moving rather than in a fixed position, so that when your dog is walking well, he doesn't feel any pressure at all on his face. This is in fact how the collar works, using a pressure and release system - pressure when pulling, no pressure when not pulling - this is your dog’s ‘reward’ for walking well and he should only feel pressure if he pulls.
If the collar was in a fixed position, there would be (at least some) continual pressure which means no actual training is taking place and your head collar is working more like a restraint. Your dog will only walk well on a loose lead and this is what we are looking to achieve.
When he is walking well, it is important to keep the lead short but just slackened off, so that it is not so loose for the nose band to come over your dog’s nose. The yellow guider underneath the chin is designed to be loose, free-moving and not fixed as the collar is a training aid to train your dog to eventually walk without pulling.
An extendable lead or similar long lead is not recommended for use with the Canny Collar.
