Our verdict
The BLACKDOG OT9 pairs a 4,200 foot range with 4 training modes, a flashlight and strobe light, and a battery Blackdog says lasts up to 3 months, and it's earned a strong 4.5 star average from 699 reviews at 79.99 dollars.
Owners who want a mid priced collar with a long working range, added visibility features like flashlight and strobe, and a battery that doesn't need frequent charging.
Skip if
You don't need flashlight or strobe functions and would rather have a simpler, lighter collar focused only on training modes.

Popularity3.8/5
699 owner reviews, more than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other dog and cat food, health, gear and grooming we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The OT9 is built by Blackdog for dogs from 5 to 150 pounds, covering nearly any size, with 4 training modes and a claimed 4,200 foot range that's well beyond typical yard or field use. It's IP67 waterproof and made from plastic and resin, weighing in at 410 grams.
Beyond training modes, it adds a flashlight and strobe light built into the collar, which can help with visibility during early morning or evening walks, a feature not every collar in this category includes. Blackdog backs it with a 2 year warranty.
At 79.99 dollars it sits in the middle of this roundup on price, and its 4.5 star rating from 699 reviews, one of the higher review counts covered here, points to a well proven track record among a large number of buyers.

What buyers say
A 4.5 star average across 699 reviews is one of the stronger combinations of rating and volume in this roundup, suggesting the collar holds up well across a large number of real world buyers rather than just a small early sample.
Blackdog rates it for dogs from 5 to 150 pounds, which covers nearly every breed size, though very small or very large dogs at the extreme ends should double check fit.
How long does the battery last?
Blackdog states the battery lasts up to 3 months per charge, longer than many collars in this category that need charging weekly.
What do the flashlight and strobe features do?
They're built into the collar housing to add visibility during low light walks, separate from the training modes, a feature not every collar in this roundup includes.
