Dog Fence Buying Guide: Wireless, In-Ground, and GPS Options Explained

Buying a dog containment system is confusing because the marketing makes every option sound perfect. Words like “invisible,” “wireless,” and “smart” get thrown around interchangeably, and the actual differences between products aren’t always clear until you’ve already bought one.

This guide cuts through the jargon. By the end, you’ll know exactly which type of fence matches your property, your dog, and your budget.

Step 1: Assess Your Property

Your property determines which fence types are practical:

Small, Flat Yard (Under 0.5 Acre)

All three types work. A wireless RF system is cheapest and simplest. An in-ground wire provides the most precise boundary. A GPS system works but is overkill for this property size.

Best option: PetSafe Stay & Play Wireless Fence ($200-$350) for simplicity, or a basic in-ground wire system ($200-$400) for precise boundaries.

Medium Yard (0.5 - 2 Acres)

Wireless RF reaches its limits. Most RF systems max out around 0.75-1.5 acres, and the circular boundary may not match your property shape.

Best option: In-ground wire (any property shape, most precise) or GPS (easier installation, portable).

Large Property (2+ Acres)

GPS becomes the practical choice. Burying wire over 2+ acres is a major project. GPS systems cover up to 1,000+ acres with the same collar.

Best option: SpotOn GPS ($999-$1,295) or PetSafe Guardian GPS (~$450).

Irregular Shape

Wireless RF is eliminated. You can’t make a circular boundary fit an L-shaped or oddly shaped property without leaving gaps or extending beyond your property line.

Best option: In-ground wire (follows any shape precisely) or GPS (draw custom boundaries via app).

Step 2: Evaluate Your Dog

Not every dog is a candidate for electronic containment:

Good Candidates

• Dogs that have already been trained on basic obedience (sit, stay, come)
• Dogs over 8 pounds (most collars have minimum weight requirements)
• Dogs over 6 months old (puppies under 6 months shouldn’t use correction collars)
• Dogs with moderate to high food motivation (makes training faster)

Poor Candidates

• Dogs with severe anxiety or fear-based behavior
• Dogs with aggressive behavior toward people or animals outside the boundary
• Deaf dogs (can’t hear warning tones)
• Dogs under 8 pounds or under 6 months
• Dogs with a history of seizures (consult vet first)

Prey Drive Consideration

Dogs with high prey drive (chasing squirrels, rabbits, cats) may blast through a containment system if the stimulus is strong enough. No electronic fence is a guarantee against determined pursuit. If your dog has extreme prey drive, physical fencing may be the only reliable option.

Step 3: Set Your Budget

Upfront Costs

System	Equipment	Installation
Wireless RF	$150-$450	$0 (plug-in)
In-ground wire (DIY)	$200-$400	$0 (your labor)
In-ground wire (professional)	$200-$400	$500-$1,500
GPS (entry)	$450-$600	$0 (walk perimeter)
GPS (premium)	$999-$1,300	$0 (walk perimeter)

Ongoing Costs

System	Monthly	Annual
Wireless RF	$0	Battery replacements (~$10-$20/year)
In-ground wire	$0	Battery replacements (~$10-$20/year)
GPS (no subscription)	$0	Charging electricity only
GPS (with subscription)	$5-$20	$60-$240

Extra Collar Costs

If you have multiple dogs, each needs its own collar. Additional collars cost:

• RF/in-ground wire: $50-$100 each
• GPS: $200-$600+ each

This is where GPS systems get expensive with multiple dogs. Two dogs on SpotOn means two collars at ~$1,000 each.

Step 4: Understand the Training Commitment

Every containment system requires 10-14 days of structured training. The fence technology is just hardware — the training is what makes it work.

Training Overview

1. Days 1-3: Flag the boundary visually. Walk the dog on leash near the flags. Let them hear/feel the warning. Redirect them away and reward.
2. Days 4-7: Increase the dog’s proximity to the boundary. The warning tone should trigger an automatic retreat. Reward heavily for turning back.
3. Days 8-10: Practice with controlled distractions (another person walking by, a toy thrown near the boundary).
4. Days 11-14: Supervised off-leash time within the boundary. Watch for boundary testing.
5. Weeks 3-6: Gradually remove visual flags. Dog should respect the invisible boundary by now.

Skipping training is the #1 reason containment systems fail. Don’t do it.

Step 5: Choose Your System

I Recommend Wireless RF If…

• Your yard is small and roughly flat
• You want the simplest possible setup (30 minutes, plug and play)
• You rent and can’t install permanent equipment
• You’re on a budget under $400
• You only need to contain one or two dogs

I Recommend In-Ground Wire If…

• Your property is irregularly shaped
• You want the most precise boundary (1-2 feet accuracy)
• You’re a homeowner and won’t be moving soon
• You have areas to exclude (gardens, pools) within the containment area
• You want zero monthly costs

I Recommend GPS If…

• Your property is larger than 1.5 acres
• You want tracking capabilities along with containment
• You need to contain your dog at multiple locations
• You don’t want to bury wire or can’t due to property restrictions
• You want the boundary to be easily adjustable via an app

Frequently Asked Questions

Are electronic dog fences humane?

Modern systems use multiple escalation levels: tone first, then vibration, then static correction. The static correction is designed to be surprising rather than painful — comparable to a static electricity shock from touching a doorknob. Most dogs learn from the tone alone after 2-3 days of training and never experience the correction level.

That said, some dogs with anxiety or fear-based behavior respond poorly to any correction. Evaluate your individual dog’s temperament before choosing an electronic system.

Can a dog run through an electronic fence?

Yes, if sufficiently motivated. A dog chasing a squirrel through an adrenaline rush may blast through the correction zone. The correction is calibrated to interrupt normal behavior, not override extreme prey drive. Physical fencing is the only truly escape-proof option.

What happens if the power goes out?

Wireless RF systems stop working immediately since the base station needs power. In-ground wire systems also lose the boundary signal. GPS systems continue working because the boundary data is stored on the collar (for most models) or in the cloud, and the collar has its own battery.

How long do fence collar batteries last?

RF and in-ground wire collars use replaceable batteries that last 3-12 months depending on usage. GPS collars have rechargeable batteries lasting 18-36 hours (GPS active) to 3 months (standby mode, Fi collar). Budget for regular battery replacement or charging as part of the ongoing cost.
