Very Vocal dog

Water pistol as above, but also have the dog on a lead 100% of the time for a while. I know its a pain but dogs feel secure on a lead and it teaches then that you are the boss, you are showing them which way to go etc. when walking do a few 180 degree turns, randomly to show her you are in charge but also if she barks or misbehaves.

Use of a lead is very much underused for dog training.

What's all this water pistol thing, do you want soggy pockets ? Some dogs would also see a water fight as a fun reward ! LOL
Time it well and correct it with good timing and mild but well timed aversion its a simple thing if its occuring close , a poke and a sharp "No!" further away is slightly harder but making a big fuss without correction well timed aint going to help . you dont want to cause pain or damage your just stopping the chain of thought . then re-direct ! Dont waste you beath and energy if you have no remote correction or you miss the event in action as the dog wont know " why" and make the connection .
