What Size E Collar/Remote Dog Training Collar Do I Get?

In terms of size of the e collar, you might look for two main things:

– The weight range of the collar i.e. it might say ‘for dogs 8lbs and over’

– The neck size that the collar fits i.e. it might say for dogs with neck sizes 6 to 28 inches



– Find out the weight of your dog

– Measure their neck size and compare it to the collar strap length that the collar comes with

– And, make sure you follow the manufacturer’s sizing specifications for the e collar you want


Safety Considerations With A Remote Dog Training Collar

Safety is extremely important with a remote dog training collar.

Always always get your vet’s advice or the advice of an animal health and/or training expert – nothing is a substitute for professional advice.

Some general safety guidelines for using an e collar humanely might be:

Buy from a reputable company who put proper use of the e collar and the safety of the dog as a priority 

Read and follow the operating guide, instruction/safety manual and training guide that comes with the e collar system from the manufacturer for operation and safety instructions and guidelines

Pay attention to any warnings issued by the manufacturer

Monitor your dog’s response both mentally and physically to using an e collar. Take the collar off immediately and discontinue use of the system if you notice any negative implications or reactions


A good remote dog training collar that uses static stimulation should simply stimulate the muscle (to the point of reflex) to get the dog’s attention, but should not cause pain (it might be slightly annoying for the dog to act as a small deterrent – but shouldn’t cause pain or harm). It certainly shouldn’t cause a ‘sharp pain’ to the muscle or body. 

To get a safe stimulation level – you can always start from the lowest stimulation level, and work your way up to a level that gets the dog’s attention (such as changing body language when a stimulation, vibration or tone is administered) without any visible sign of pain or harm (such as yelping, or showing signs of stress).

A good e collar company should give you all the necessary safety, use and training instructions, and should have a dedicated customer service line to help when you being using the collar system.

The static stimulation function does not need to be used either – tone and vibrate training modes can be used instead.

Some owners like to even use their e collar as a temporary training tool, and may go back to using body or verbal commands once behaviors are reinforced (if suitable).
