INVIROX Shock Collar Review: Game-Changing Training?

First Impressions

Have you ever felt helpless when your furry friend bolts off during a walk, ignoring your calls? I certainly have, and that’s exactly why I decided to try the INVIROX Shock Collar for Dogs. My energetic German Shepherd, Max, needed some help with recall training, and I wanted a safe and effective solution.

When the package arrived, I was immediately impressed. The packaging felt sturdy and professional, and the collar itself had a solid, well-built feel. The remote fit comfortably in my hand. Right out of the box, I could tell that the INVIROX collar was a cut above other training devices I’d seen. The biggest surprise? Max actually responded to the training!

If you’re curious to know how the INVIROX Shock Collar for Dogs performed in real-world scenarios, and whether it truly lived up to its claims, keep reading for my detailed review.

Key Features & Specifications

Alright, let’s dive into the features of the INVIROX Shock Collar for Dogs [Ultra K9] 124 Training Levels, 4 Powerful Modes with Night-Light and ¾ Mile Range 100% Safe Dog Training Collars for Large Dogs IP67 Waterproof E Collar. I’ve put this collar through its paces with my energetic German Shepherd, Max, and here’s what I’ve discovered:

Veteran-Designed Training Modes

The INVIROX Shock Collar for Dogs [Ultra K9] boasts an impressive array of training modes, fine-tuned with 124 training levels. You get beep (1-8), vibration (1-16) and stim mode (1-99) . This isn’t just a gimmick; it’s about having granular control over the correction you administer. For instance, when Max starts barking at the mailman, I usually start with the beep, then vibration, if needed. It’s much more humane than a one-size-fits-all approach.

What sets this INVIROX Ultra K9 apart is the ability to find that perfect level of stimulation. With some other collars I’ve tested, the jumps between levels were too drastic. The subtle increments here allow you to communicate effectively with your dog without causing undue stress. I’ve found level 15 on the stim mode to be effective with Max, which is a low enough setting to simply get his attention. Plus, I appreciate the added ergonomic remote design offering three convenient carrying options; belt clip, lanyard and wrist strap.

Lab and Field-Tested Safety Features

The biggest concern with any e-collar is safety, and INVIROX seems to have taken that to heart. This safe training collar is designed to prevent accidental shocks, thanks to the integrated keypad lock. There is nothing worse than accidentally shocking your dog when you are not intending to.

I intentionally tried to trigger accidental shocks by fumbling with the remote, dropping it, and even having my kids play with it. The keypad lock is a serious feature that gives you peace of mind, especially if you have kids around. I also appreciate that they have lab tested and field tested this collar to ensure that it is safe to use on your furry friend!

100% Waterproof and Weatherproof Design

The INVIROX Shock Collar for Dogs [Ultra K9] proudly touts an IP67 waterproof rating for the collar itself and IP65 for the remote. This means you don’t have to worry about rain, snow, or even a quick dip in the lake. The INVIROX Ultra K9 is built to stand up to any elements you throw at it.

We recently went on a camping trip where it rained cats and dogs. Max, of course, loved splashing in every puddle he could find. I was relieved to know that the INVIROX Shock Collar for Dogs [Ultra K9] could handle it. It performed flawlessly, even after being submerged several times. I also like that I can use this training collar for dogs as light as 8 lbs~150 lbs size dogs

Unmatched Range for Off-Leash Training

The INVIROX Shock Collar for Dogs [Ultra K9] boasts a ¾ mile range, which is impressive. In my experience, that range holds up well in open fields. I was able to maintain a strong connection with Max even when he was exploring the far reaches of the local dog park.

Living out in the country, this range is a game-changer. I can let Max roam a bit more freely without losing the ability to communicate with him. Just be aware that obstacles like trees and buildings will naturally reduce the range. The best shock collar for large dogs lets you train your dog like a PRO!

🚫 Serious Hunters or Field Trainers

Pros & Cons

Okay, here’s my take on the INVIROX Shock Collar for Dogs [Ultra K9]. I’ve been using it for a couple of weeks now with my overly enthusiastic Golden Retriever, Max, and here’s what I’ve found:

Pros:

• Impressive Range: The ¾ mile range is no joke. I tested it out in a large open field, and I was able to maintain consistent communication with Max even at a significant distance. This gave me real peace of mind during off-leash training.
• Customizable Stimulation: The 124 training levels are a game-changer. It allowed me to really fine-tune the stimulation to Max’s sensitivity level. Started super low and gradually increased until I got the desired response, without causing him any distress.
• True Waterproofing: The IP67 rating lived up to the hype! Max loves to swim, and I’ve had no issues with the collar malfunctioning even after he’s been completely submerged in the lake. It’s definitely a relief to not worry about water damage.
• Safety Lock Feature: I appreciate the keypad lock that prevents accidental shocks. It’s a small feature, but it’s given me a ton of confidence that I won’t mistakenly activate the stimulation mode when the remote is in my pocket.
• Multiple Training Modes: The beep, vibration, and stimulation modes offer flexibility. I started with the beep and vibration settings to redirect Max’s attention. Only after those failed did I cautiously introduce the lowest stimulation level.
• Long Battery Life: The battery life is outstanding. The remote lasted nearly a month on a single charge. The collar lasts well over a week, even with daily training sessions.
• Comfortable Design: The collar itself seems comfortable for Max. He doesn’t try to scratch or remove it, which is a good sign. The adjustable strap ensures a snug but not too tight fit.

Cons:

• Stimulation Curve: Even with 124 levels, the jump between the very lowest levels can be noticeable, especially for sensitive dogs. Took a few sessions to dial in the perfect setting for Max.
• Remote Size: The remote, while ergonomic, is a bit bulky. I wish it was a bit more compact for easier carrying. But it’s understandable given the range and features packed in.
• Night Light Dim: While the night-light is a nice addition, it isn’t super bright. It is helpful for locating Max in the dark, but it won’t illuminate a large area.

How It Compares

Okay, here’s a competitive comparison of the INVIROX Shock Collar for Dogs [Ultra K9] based on my experience with it and some similar models.

INVIROX Shock Collar for Dogs [Ultra K9] vs. Petrainer PET998DRB1

I’ve spent quite a bit of time working with different e-collars, and the Petrainer PET998DRB1 is one I used before I got my hands on the INVIROX Shock Collar for Dogs [Ultra K9]. The Petrainer is a decent, budget-friendly option, but after using the INVIROX Shock Collar for Dogs [Ultra K9] for a few weeks, the differences become pretty clear.

First, the range on the INVIROX Shock Collar for Dogs [Ultra K9] is noticeably better. They advertise a ¾ mile range, and while I haven’t exactly measured that, I can confidently say it outperforms the Petrainer in open fields. With the Petrainer, I sometimes struggled with connectivity beyond a couple hundred yards, while the INVIROX Shock Collar for Dogs [Ultra K9] remained reliable even further out. That added range gives me peace of mind when letting my energetic Golden Retriever, Gus, off-leash at the park.

Another area where the INVIROX Shock Collar for Dogs [Ultra K9] wins is the sensitivity and control over the stimulation levels. With 124 levels, you can really fine-tune the correction to find what works best for your dog. The Petrainer has fewer levels, which sometimes felt like too big of a jump between settings. Getting that stimulation just right is important for responsible training.

The one thing the Petrainer has going for it is the simpler remote design. It’s very basic and straightforward. Some people might prefer that if they are intimidated by a lot of buttons, but for me, the added functionality and control offered by the INVIROX Shock Collar for Dogs [Ultra K9] are worth the slightly steeper learning curve. I’d recommend the INVIROX Shock Collar for Dogs [Ultra K9] if you’re looking for reliability and precise control during training sessions.

INVIROX Shock Collar for Dogs [Ultra K9] vs. SportDOG Brand FieldTrainer 425

The SportDOG Brand FieldTrainer 425 is another popular e-collar, and it’s definitely a step up in terms of overall build quality compared to some of the cheaper options. I actually liked the rugged feel of the SportDOG. However, the INVIROX Shock Collar for Dogs [Ultra K9] still edges it out in a few key areas.

The INVIROX Shock Collar for Dogs [Ultra K9] includes a night-light feature, which is surprisingly useful for evening walks. The SportDOG lacks this, and it’s a feature I appreciate, especially during the darker winter months when Gus still has energy to burn after dinner. Being able to activate a light on the collar to keep an eye on Gus is a real bonus.

Also, the INVIROX Shock Collar for Dogs [Ultra K9] has that higher range. The SportDOG states a range of up to 500 yards, but, in my experience, the INVIROX Shock Collar for Dogs [Ultra K9] gave me a stronger, more consistent signal, especially when there were obstructions like trees or buildings nearby.

Where the SportDOG shines is its reputation and history in the dog training world. SportDOG has been around for a long time, and they’re a well-respected brand. If brand recognition and a proven track record are important to you, then the SportDOG might be a good choice. But, if you’re after a slightly more feature-rich collar with better range and a handy night-light, the INVIROX Shock Collar for Dogs [Ultra K9] is definitely worth considering.

Lisa from Suburban Ohio, First-Time Dog Trainer: “I was honestly a little nervous about using a shock collar, but the INVIROX Ultra K9 made me feel comfortable.

My Experience

My Three Months with the INVIROX Shock Collar for Dogs [Ultra K9]

When I first integrated the INVIROX Shock Collar for Dogs [Ultra K9] into my daily routine back in January, I was primarily looking to curb my overly enthusiastic Labrador, Gus’s, habit of chasing squirrels into the neighbor’s prize-winning rose bushes. What I didn’t expect was how it would completely change my approach to off-leash training.

During a particularly frustrating incident last month, the INVIROX Shock Collar for Dogs [Ultra K9] proved its worth when Gus spotted a deer during our usual walk in the woods behind my house. Before I could even react, he was off, bounding through the trees. Normally, this would result in a frantic chase and a lot of yelling on my part. But this time, I remembered the remote in my pocket. I pressed the vibrate button, and to my complete surprise, Gus stopped dead in his tracks, turned around, and came trotting back to me. It felt like a small miracle.

I’ve been testing the INVIROX collar now for about three months. My wife even tried it out a few times when she took Gus for walks in the park. The remote fits comfortably in my hand and the buttons are easily accessible, even with gloves on during our colder morning walks. The collar itself feels quite sturdy and the IP67 waterproof rating definitely came in handy during a particularly rainy hike. I was initially concerned about the “shock” aspect, but the adjustable levels and the vibrate/tone options really put my mind at ease. I honestly rarely have to use anything beyond the tone function anymore.

One unexpected benefit I discovered was the night-light. We often let Gus out for a potty break before bed, and the light makes it easy to keep track of him in the dark backyard. The ¾ mile range is impressive. While I haven’t needed to use it at that distance, it gives me peace of mind when we’re in more open areas.

I did initially have a bit of trouble figuring out the optimal level for Gus. It took some careful observation to find a setting that got his attention without causing him any distress. But once I found the sweet spot, it made a world of difference. I’ve used other training collars in the past, but the INVIROX’s range and multiple modes offer more precise control, and the battery life is noticeably better.

Final Verdict

Final Verdict

After a couple of weeks putting the INVIROX Shock Collar for Dogs [Ultra K9] 124 Training Levels, 4 Powerful Modes with Night-Light and ¾ Mile Range 100% Safe Dog Training Collars for Large Dogs IP67 Waterproof E Collar to the test with my headstrong German Shepherd, Max, I’ve formed a pretty solid opinion. He’s usually a good boy, but his recall when squirrels are involved? Forget about it! This collar has been instrumental in improving that. While the sheer number of training levels – 124! – felt a little overwhelming at first, I appreciated the granular control it offered, allowing me to find the perfect setting for Max without overdoing it.

I think owners of particularly stubborn breeds, or those working on very specific behavioral issues like excessive barking or chasing, will benefit the most from the INVIROX Shock Collar for Dogs [Ultra K9] 124 Training Levels, 4 Powerful Modes with Night-Light and ¾ Mile Range 100% Safe Dog Training Collars for Large Dogs IP67 Waterproof E Collar. The biggest strength, without a doubt, is its range. The ¾ mile claim held up even in my slightly wooded neighborhood, which is fantastic. The biggest limitation, honestly, is that initial learning curve. You really need to read the instructions carefully and start at the lowest settings to avoid any discomfort for your dog.

Overall, I recommend the INVIROX Shock Collar for Dogs [Ultra K9] 124 Training Levels, 4 Powerful Modes with Night-Light and ¾ Mile Range 100% Safe Dog Training Collars for Large Dogs IP67 Waterproof E Collar, but with reservations. It’s a powerful tool, and with great power comes great responsibility! If you’re committed to responsible and ethical training, and especially if you have a larger dog with some serious focus issues, it’s worth considering. At the current price, the INVIROX Shock Collar for Dogs [Ultra K9] 124 Training Levels, 4 Powerful Modes with Night-Light and ¾ Mile Range 100% Safe Dog Training Collars for Large Dogs IP67 Waterproof E Collar is a competitive option with excellent range and customization. Just be sure to prioritize your dog’s well-being and use it judiciously.
