Review on 🐶 Inoosky Ultrasonic Dog Bark Deterrent: Effective Anti-Barking Device & 2-in-1 Training Tool by Victoria Smith

My dog doesn't bark often but we have been trying for years to stop him from barking at people who walk/ride/bike near our home. We live on a semi-quiet street, but when the weather is good people like to go for a walk and then my dog's barking gets annoying. This is a large dog, over 100 pounds and 4 years old. The description of the device says "FOR DOGS OF ALL SIZES" and there is also a picture showing the age of use for dogs from 6 months to 8 years. This was something I was concerned about, so I made sure the device would actually work for my dog. Upon arrival I noticed that there are a number of pictures in the instruction manual showing what works and what doesn't with this product. There is a particular image that is less than £50 with a check and more than £50 with an 'x'. In fact, this device is not recommended for dogs over 50 pounds. That being said, the device still seems to be effective about half the time. However, if I had known the size recommendations beforehand, I would not have bought this device.
