Leave it or Off has worked well for us with our dogs. You could also try the Gentle Leader or Halti--they are not muzzles (they go over the dogs face but the dog can still open its mouth/eat/etc) and I have found the Gentle Leader to be amazing. Our one beagle was nearly impossible to walk and he will do 'off' inside the house but not so reliably when we are outside on walks. The Gentle Leader calls itself something like the 10 minute attitude adjuster and it really is. Walks are much more fun now and I know our dog is safe from himself!
