E-collar basics

Is an e-collar the same as a shock collar?

Many people call remote training collars “shock collars,” but a modern e-collar is a communication tool with three signals: a tone, a vibration, and adjustable electronic stimulation that starts at a level most dogs barely notice. Each signal works like a tap on the shoulder at a distance, paired with a command and a reward. The goal is clear communication, not correction.

How does a remote dog training collar work?

You hold a remote and your dog wears a small receiver on the collar. A button press sends a tone, a vibration or a low-level stimulation to the receiver, from up to 1,100 yards away on INVIROX models. Teach each command on a leash first, then pair it with the lowest signal your dog notices, so the collar extends your voice when your dog is far away or distracted.

Do e-collars hurt dogs?

Used correctly, no. Training happens at the lowest level your dog responds to, which for most dogs feels like a light tingle, similar to a phone vibrating in your pocket. Problems come from misuse: starting too high, poor timing, or using the collar in frustration. INVIROX collars start at level 1, include tone and vibration-only modes, and have a keypad lock against accidental presses. If your dog shows fear, stop and reset with tone or vibration only.

What's the difference between tone, vibration and stimulation?

Tone is a beep your dog learns to link with a command or a reward marker. Vibration is a buzz with no electrical stimulation, useful for sensitive or deaf dogs. Stimulation is an adjustable electronic signal (up to 99 levels on INVIROX collars) used at the lowest level your dog notices. Most owners use tone and vibration for everyday cues and low stimulation only when the dog is distracted or far away.

Do I need stimulation, or is a vibration collar enough?

Many dogs, especially small or sensitive ones, train well on tone and vibration alone. Every INVIROX e-collar includes both, so you can start there and only use stimulation if vibration stops working at a distance or under heavy distraction. You don't need to buy a separate vibration-only collar.

Can I use an e-collar with a deaf dog?

Yes. Vibration is a common way to communicate with deaf dogs. Teach the vibration as a “look at me” cue by pairing it with a treat every time, and your dog learns to check in with you when it feels the buzz. A deaf dog doesn't need the tone function.

At what age can my puppy start e-collar training?

INVIROX recommends 6 months or older, once your puppy knows basic commands on a leash and meets the minimum weight for the model (8 lbs for the 2027 Edition). Younger puppies learn best with a leash, treats and short sessions.

Are e-collars legal?

In the United States there is no federal ban on e-collars, though some states and cities have rules on how dogs may be tethered, so check local regulations. Several countries ban or restrict them, including England (Animal Welfare (Electronic Collars) (England) Regulations 2023), Wales, Germany, Switzerland, Sweden, Norway, Denmark, Spain and Quebec. This is general information, not legal advice. If you live outside the US, check local rules before buying.

How long does e-collar training take?

Most dogs understand basic cues on the collar within 1–2 weeks of short daily sessions (5–10 minutes). Reliable off-leash recall under distraction usually takes several weeks. The INVIROX Elite K9 14-Day Protocol gives you a day-by-day plan.

Can a remote training collar help with barking?

It can help when you're there to mark the moment your dog starts barking and redirect it, using tone or vibration first. It won't manage barking while you're away. Barking usually has a cause (boredom, alerting, anxiety), and training that addresses the cause works better than any device on its own.

Choosing your INVIROX collar

Which INVIROX e-collar is right for my dog?

2027 Edition: dogs 8–110 lbs, everyday training, best value. Waterproof collar; remote is not waterproof.
SPARK K9: dogs 30–150 lbs, recommended for long or thick coats. IP67 waterproof collar, up to 1,100-yard range.
ULTRA K9: dogs 8–150 lbs, IP67 collar and IP65 remote, 1,100-yard range, built for field and hunting use.
X2 systems: two dogs on one remote ( 2026 X2, SPARK K9 X2, ULTRA K9 X2).

What's the best e-collar for small dogs?

Look for a light receiver, a low starting level and a vibration mode. The INVIROX 2027 Edition fits dogs from 8 lbs, starts at level 1 and includes tone and vibration. Always use the rubber prong covers on small dogs and check the fit daily.

What's the best e-collar for large or stubborn dogs?

Large dogs need range, a stable fit through a thick neck and enough adjustment to find their working level. SPARK K9 and ULTRA K9 fit dogs up to 150 lbs with up to 1,100 yards of range. “Stubborn” usually means the dog hasn't fully learned the command yet, so turning the level up rarely helps; better timing and foundation work do.

Can one remote train two dogs?

Yes. INVIROX remotes can control up to 2 dogs, and the X2 systems include both collars paired to one remote. You switch between dogs with one button, and each dog keeps its own level.

Which INVIROX collar is best for hunting and long range?

The ULTRA K9, including the Hunting Limited Edition in camo. It reaches up to 1,100 yards in open terrain, with an IP67 waterproof collar and an IP65 waterproof remote for rain, water retrieves and cold mornings. Range drops in dense woods and hilly ground, so test your levels in the field before a hunt.

Will an e-collar work on long or thick fur?

Yes, as long as the contact points touch the skin. For long or double coats (German Shepherds, Huskies, Malinois), use the long metal prongs with rubber covers, part the fur where the receiver sits, and choose SPARK K9 or ULTRA K9. A bungee collar helps keep contact without over-tightening.

Is the INVIROX e-collar waterproof?

All INVIROX e-collar receivers are rated IP67, so they handle rain, lakes and short swims. Remotes differ: the ULTRA K9 remote is IP65 (rain and splashes), while the 2027 Edition remote is not waterproof. Rinse and dry the collar after salt water.

How does INVIROX compare with premium e-collars that cost $200 or more?

INVIROX collars cover the same essentials: tone, vibration, fine-grained stimulation levels, waterproof receivers and up to 1,100 yards of range, at a lower price, and they're designed by K9 handlers. Premium brands may offer lighter micro receivers or longer track records. Compare the specs that matter for your dog: its weight, the range you'll really use, and waterproofing.

Do INVIROX collars need an app or a subscription?

No. INVIROX e-collars and wireless fences work straight out of the box with the included remote or base unit. No app, no Wi-Fi, no SIM card and no monthly fee.

Setup, fit and safe use

Where do I start with e-collar training?

Read your user manual first ( ULTRA K9, SPARK K9, INVIROX collar). Teach the command on a leash, then pair it with tone or low vibration and a reward. Keep sessions to 5–10 minutes. If you're unsure, work with a professional trainer.

How do I pair the remote to the collar?

Hold the receiver's power button for 3 seconds to turn it on.
Click the power button 3 times to enter pairing mode.
Press a training mode button on the remote. The receiver confirms the pairing.

How do I fit the collar correctly?

Snug enough that both contact points touch the skin, loose enough to slide one finger under the strap. Place the receiver on the side of the neck, move it to a different spot every 1–2 hours, and check the skin daily for redness.

How long can my dog wear the collar each day?

No more than 8 hours a day. Move the receiver to a different spot on the neck every 1–2 hours, use the rubber covers, and take the collar off overnight.

Should I use the rubber covers?

Yes. The rubber covers protect your dog's skin and prevent irritation, especially when the collar is worn for more than 2 hours. Replacement prongs and covers are available.

How do I find my dog's working level?

Start at level 1 in a quiet place and go up one level at a time until you see a small sign your dog notices: an ear flick, a head turn, a pause. That's the working level. Most dogs respond in the low range. Raise it slightly for high-distraction settings and go back down when things are calm.

What are the most common beginner mistakes?

Starting at too high a level, poor timing, using the collar in frustration instead of as communication, and a loose fit that loses skin contact.

My dog ignores the collar. Why?

Usually one of three things: the contact points aren't touching the skin, the environment is too distracting for the current level, or the dog doesn't understand the command yet. Check the fit, move to a quieter place, and build up gradually.

My dog seems scared of the collar. What should I do?

Stop the session. Fear means the level, the timing or the foundation needs work. Go back to tone and low vibration only, pair every signal with rewards, and consider working with a professional trainer before continuing.

How do I prevent accidental button presses?

Use the remote's keypad lock whenever you're not actively training, and practice button placement a few times without your dog before a session.

How do I check that the collar is working?

Use the tester light included in the box: hold it against both contact points and press a stimulation button. If it lights up, the unit works. If your dog doesn't respond, check skin contact and fit first, and use longer prongs for thick fur.

How long does the battery last, and how do I charge it?

On ULTRA K9 and SPARK K9, the collar lasts up to about 15 days of use per charge, with longer standby. The GPS fence collar runs up to 24 hours continuously. Charge with a 5V USB charger; a full charge takes about 2–3 hours on ULTRA K9. Charging cables and 5V charger blocks are sold separately.

How do I assemble the collar strap?

Step-by-step strap assembly is in your user manual ( ULTRA K9, SPARK K9, INVIROX collar). Replacement TPU straps and bungee collars are available.

Wireless dog fences (GPS and Radar)

What's the difference between a GPS fence, a radar fence and an in-ground invisible fence?

An in-ground invisible fence uses a buried wire, which takes installation and can break. A GPS fence ( INVIROX GPS) draws a circle up to 999 yards around a center point with no wire or base station, suited to large open properties. A radar fence ( INVIROX RADAR) uses a base station to set a precise 10–120 ft boundary, suited to typical yards and indoor areas.

Is there a GPS dog fence with no monthly subscription?

Yes. The INVIROX GPS Wireless Dog Fence has no subscription, no app, no SIM card and no Wi-Fi. You set the center and radius on the collar, with GPS accuracy of 1–2 yards, and it works anywhere with open sky.

Is the INVIROX GPS fence an alternative to Halo or SpotOn?

Yes, for owners who want a GPS boundary without an ongoing fee. Halo and SpotOn offer app features, custom-shaped boundaries and tracking, with subscriptions or higher prices. INVIROX GPS is a one-time purchase with a circular boundary up to 999 yards and no app. If you need an irregular boundary shape or live location tracking, an app-based system is the better fit.

Can I take a wireless fence camping or traveling?

Yes, with the GPS fence. There's no base station, so you set a new center point wherever you are and the boundary moves with you. Walk your dog along the new boundary on a leash a few times first.

Which wireless fence works for small yards or indoors?

The RADAR fence. Its boundary can be set from 10 to 120 feet, far tighter than GPS allows, and it works inside the house, for example to keep a dog out of the kitchen.

Can one wireless fence contain two or three dogs?

Yes. One RADAR base station supports up to 3 collars, with 2-dog and 3-dog kits available. Each GPS collar holds its own boundary, so several can run at once.

Do wireless dog fences work for small dogs?

They can, if the collar fits the neck and the dog is introduced gradually with warning tones and leashed boundary walks. The GPS collar fits necks from 7 to 22.5 inches and the RADAR collar 6 to 23 inches. RADAR is designed mainly for medium and large breeds.

Will my dog get a correction when coming back into the yard?

Not with RADAR. It uses correction-free re-entry, so a dog returning to the safe zone gets no signal. Rewarding your dog for turning back is what makes the boundary stick.

How much does a wireless fence cost compared with a traditional fence?

A wood or chain-link fence for an average yard often costs thousands of dollars installed. A wireless fence is a one-time purchase of a few hundred dollars, installs in minutes and moves with you. It's a training system, though, and won't keep other animals out.

Where should I place the RADAR base station?

Away from routers, heavy electronics and large metal objects, with a clear path to the area your dog moves in. Confirm the boundary is stable in Test Mode before switching to Working Mode.

Why does my RADAR fence lose signal?

Check that the boundary is within range, move the base station away from Wi-Fi, Bluetooth and other electronics, and test again in Test Mode before going back to Working Mode.

My dog crossed the GPS boundary. What went wrong?

Usually the dog hasn't learned the boundary yet, the radius is too small, or off-leash use started too early. Go back to leashed boundary walks with warning cues and rewards for turning back.

My dog is afraid of the boundary. How do I rebuild confidence?

Pause unsupervised use for 3–7 days, lower the intensity, and return to leashed walks near the boundary, rewarding every turn back toward the safe zone.

How do I stop my dog from creeping toward the boundary?

Address it early with 5–7 days of daily leashed boundary practice, rewarding your dog for turning back before it learns to linger near the edge.

Bully sticks and dog beds

Are bully sticks safe for dogs?

Yes, when you supervise and pick the right size. Bully sticks are single-ingredient, digestible beef chews. Take away the last 1–2 inches before your dog can swallow it whole, and choose a stick your dog can't fit entirely in its mouth. Our bully stick reward protocol shows how to use them safely after training.

Do I need a bully stick holder?

A holder helps fast or aggressive chewers by keeping the end out of swallowing range. If you supervise and take the last piece away, you don't need one.

Are bully sticks OK for puppies?

Generally yes for puppies over about 12 weeks, in short supervised sessions, and they can help with teething. Start with 10–15 minutes and ask your vet if you're unsure.

Why don't INVIROX bully sticks smell, and where do they come from?

They're oven-baked, which removes most of the odor while keeping the chew natural. Each stick is a single ingredient: grass-fed beef pizzle, sourced from Brazil. Sourcing and safety standards are listed in our compliance and safety hub.

Where can I buy INVIROX bully sticks?

On invirox.com in 5, 10, 15, 20 and 25 packs, with a subscribe-and-save option, and at Chewy.

Is the INVIROX XL bed a good orthopedic bed for large or senior dogs?

Yes. The INVIROX Luxury XL Dog Bed measures 45″ × 35″ × 7.7″ with a 33″ × 23″ sleep area and a 4″ orthopedic memory-foam base, and suits dogs up to 150+ lbs. The high-density foam supports joints, which helps large, senior and arthritic dogs.

Is the dog bed cover washable?

Yes. The plush cover is machine-washable and replaceable, and a waterproof inner liner protects the foam from accidents. The base is anti-slip.

What does CertiPUR-US certified foam mean?

CertiPUR-US is a nonprofit certification for foam made without formaldehyde or regulated phthalates and with low chemical emissions for better indoor air. The foam in the INVIROX XL bed is CertiPUR-US certified; see our compliance and safety hub.
