Anti dog bark collar

I have a great dane that barks too much. What is out there that can helo me? Any advice?

How old is it? My neighbor tried using my track and train collar but his great Dane was way too big for it at 6 months. You will need one that you can control the strength and type of stimulation. Look for a used garmin trash breaker system. Depending on your dog's size you might need to expand the collar

Lemon juice.

I've got a Tri-Tronics (Garmin) bark collar deluxe & it works wonders. You might need to get 2 collar straps & tie them together

He's 3 years old and 120 pounds. Not a bug fane but very stubborn. And loud.

Bark collars work great. They start with low volts and build up if the dog continues to bark. Dont have him/her wear it more than 8 or 10 hours at a time or the 2 prongs can rub holes. Put it on pretty snug because the prongs have to contact skin.

If you go the bark collar route, put the collar on the dog and let the dog wear it for a week before it ever gets a charge. Dogs are smart and if you immediately start hitting him with voltage he'll make the connection to the collar. Not a big deal until you take the collar off and the dog starts barking again.
