A muzzle is an effective humane tool for dog training.
The basket type muzzles are the best for the dog because they will allow them to pant and drink water.
Muzzle training your dog does not need to be hard and stressful.
Slowly introduce the dog to the muzzle.
Let the dog sniff the muzzle.
Put treats in the muzzle & let him put his nose inside to get the treat out.
Some customers use peanut butter, dog food or treats.
Make the muzzle a happy and positive thing.
For some dogs getting them comfortable with the muzzle can be done within 20 to 30 minutes, for other dogs it might take a few days.
Once you feel the dog is not afraid of the muzzle put it on him.
During this time be sure to praise him.
Some dogs actually associate putting their muzzle on with getting to go outside.
