When buying a dog deterrent, you must understand some basic components. When buying a new dog training tool, you must keep the following points in mind:

There are two types of dog repellents available, handheld and fixed. Hand-held tools can be carried with you; they are portable and used to train or frighten dogs on the go. Generally, these devices use rechargeable AAA or 9V batteries. In contrast, fixed equipment is designed to be installed in a fixed location. These devices use sensors to detect nearby animals.

Please note that stationery deterrents are only used to drive animals away. You cannot use them to train/teach your dog. However, the hand-held tool can be used as an insect repellent, as a training device, or both.

Advanced and high-quality handheld dog training can reach a range of 30 feet. In contrast, stationary insect repellents can easily cover 50 feet.

Most new stationary dog ​​repellers run on solar power, but they are also powered by backup batteries. Whenever the solar energy runs out, the backup battery will start and help the equipment to function.

The situation of hand-held dog training equipment is slightly different. They are powered by 9V or AAA batteries, and the average use time can reach 60 days. In addition, some tools provide charging capabilities, while others require new batteries when the old batteries are exhausted.

Finally, of course, it is also important that the dog training tool has some additional functions. Some have variable/fixed frequency buttons and lights, while others have different modes. Based on your usage, choose a device that includes your preferred features.
