Fun games for Muzzle Desentization

Hi everyone,

I have a small Cavalier King Charles Spaniel who has aggressive tendencies around other dogs. For safety's sake(better be safe than sorry )I have decided to teach him to wear the muzzle. He has already had one bad experience with it and this time I want to really take a lot of time and teach him to love wearing it!

I have a Baskerville Ultra and as of now I have begun to associate the muzzle with treats. Every time the muzzle comes out so do the treats. I was wondering if anyone has any suggestions of games I can play with the muzzle to really reinforce that muzzle=good stuff.

Suggestions can include things to do while wearing it or just getting him used to being around it. Creativity is much appreciated!
