Sportdog sbc-r
I purchased two of these collars for my dogs, a 2 year old Shih Tzu and an 8 year old Cairn X Terrier.
The Shih Tzu has been a barking menace his whole life and he tends to set off our older dog.
We put the collars on our dogs, which are both 7kgs and within two days they had stopped 95% of their barking. I have had both collars set to level 1, being the most gentle setting.
Now as soon as the dogs see the collars come out they are on their best behaviour.
We put the collars on the dogs for a few hours when out and have had no further complaints since.
I have used cheaper collars in the past and They did nothing. Spent the Money on a great product once and never look back.
Highly recommended
