A great result, the bark collar I got is very effective. I needed it to control my dogs barking. I have 2 dogs but only 1 of them need to be trained. She barks constantly, starts barking at 5am until late morning; they bark at people. I started getting complaints from the neighbours and was worried that the shire would get involved. My biggest concern was that the electric shock would hurt my dog, but after watching the videos I thought I would give it a try. The training was easy to follow and my dog settled in nicely. Now; she’s so much better; I dont need to worry that neighbors anymore. Also I no longer use it always; just selective like every 2 months or when we have occasions. As for the battery; I just charge it often and that is the only effort on my end; other than that he collar is very helpful and the owner. Colin too is very kind and helpful.
