Large-dog selection checklist

For a large dog, start with measured fit, age and weight. PawTronic combines GPS boundary alerts with app-controlled training; a paired remote is optional. Check measurements before shopping.

Neck range

Measure neck circumference and compare it with the 8 to 25 inch range. Breed alone does not confirm fit.

Age and minimum weight

The dog must be over six months old and weigh at least 7.9 lb.

Boundary area

Compare circle radius or polygon acreage with your property. Fence settings and handler-selected training cues are separate.

Outdoor signal and training

Clear outdoor GPS reception and supervised training matter. The 36-hour figure is standby, not active-use battery life.

How it works

4 alert choices

A clear cue at the boundary

Draw your boundary in our free app and save it to the collar. When your dog crosses that boundary, the selected alert starts. It stops when your dog returns inside. Help your dog learn the cues with supervised practice.

  • Sound: A clear audible boundary cue.
  • Vibration: A vibration-only boundary cue.
  • Sound + vibration: Two cues used together.
  • Sound + vibration + static correction: The full selectable alert mode.

Frequently asked questions about Shock Collars for Large Dogs

About PawTronic Pro Series 2

The stated fit range is 8 to 25 inches. Measure around your dog's neck where the collar will sit and confirm a secure adjustment within that range. The dog must also be older than six months and weigh at least 7.9 lb.

PawTronic supports handler-controlled training through the app, separately from its GPS boundary alerts. An optional paired remote has individual beep, vibration and static buttons. Check the product listing for accessory details, and measure the dog's fit before choosing a setup.

Circular radius settings range from 82 to 7,000 feet. A custom eight-sided polygon can cover 0.5 to 200 acres, and up to six layouts can be saved. Property conditions and outdoor GPS reception still matter.

Pro Series 2 provides up to 36 hours of GPS standby per charge. Everyday battery life varies with activity, GPS conditions and alert frequency. USB-C charging takes approximately two to three hours.

Yes. You can save up to six layouts in the app, using a circle or custom eight-sided polygon within the supported size range. Clear outdoor GPS reception matters.

Understanding Shock Collars for Large Dogs

Shock collars for large dogs include products for different training tasks, so compare how each one delivers cues. PawTronic is a GPS boundary collar with handler-controlled training through the app. Measure neck size and check age and weight criteria rather than relying on a breed label.

Compare measured neck fit, age and weight requirements, boundary settings and training controls. PawTronic combines GPS fence alerts with app-controlled training. An optional paired remote offers separate cue buttons; check the listing to see whether it is included or purchased separately.

A dog's size alone does not determine which alert setting suits their training. PawTronic offers sound, vibration and combined boundary modes, with static correction available as one option. Use the fitting and training guidance, observe your dog's response and keep practice supervised while they learn the boundary.

Many electronic training collars offer sound or vibration modes. Check the specific model rather than choosing by dog size alone. Introduce the selected cue consistently through short, supervised sessions and rewards.

Multi-dog systems need a compatible receiver collar for each dog and controls that support the intended setup. Check each dog’s neck measurement and train individually before working with both dogs together.
