The best choice depends on whether you need an automatic boundary, remote training, or both. The MIMOFPET combines a portable wireless fence with remote training and is designed for small breeds; PetSafe offers a simpler circular containment system. For remote training without fence containment, PATPET and HapTop provide adjustable training modes, while the GPS system is listed for dogs weighing 18 pounds or more. Check your dog’s weight and the product’s operating mode before choosing.
| Product | Best suited for | Important distinction |
|---|---|---|
| MIMOFPET Wireless Dog Fence | Small dogs and portable boundary use | Fence alerts are beep and vibration; no automatic static in fence mode |
| PetSafe Wireless Pet Containment System | Wireless circular yard containment | Up to 1/2 acre coverage |
| GPS Wireless Dog Fence | Dogs weighing at least 18 pounds | GPS fence and separate remote training modes |
| PATPET Training Collar | Remote training for dogs 8–120 pounds | Training collar, not a fence system |
| HapTop Training Collar | Remote training and two-dog households | Training collar, not a fence system |
MIMOFPET Wireless Dog Fence

Best for: Owners of small dogs who want a portable boundary system alongside a remote training collar. The product is described as designed for small breeds and combines fence and training functions.
The adjustable fence range has 14 settings from 25 to 3,500 feet. When a dog crosses the boundary, the collar gives a beep and vibration warning. The separate remote training mode offers beep, vibration, and static settings, with a stated remote range up to 5,900 feet.
Important limitation: Fence mode does not automatically use static correction. Choose this if warning signals are suitable for your containment plan; avoid it if you specifically require automatic static correction at the boundary.
PetSafe Wireless Pet Containment System

Best for: Buyers who want a wireless circular boundary around a home or yard without burying wire. The system’s portable indoor transmitter creates an adjustable circular coverage area of up to 1/2 acre.
PetSafe describes its boundary as a way to guide a dog back toward the play area. Setup does not require digging or burying wire, and the listing says coverage can be expanded with an additional transmitter.
Important limitation: The available product information does not specify small-dog weight suitability or correction details. Confirm those requirements with the full product information before selecting it for a small dog.
GPS Wireless Dog Fence With Remote Training

Best for: Owners whose dogs meet the stated 18-pound minimum and who want GPS-based containment plus remote training. Fence radii are adjustable from 25 to 999 yards, while remote training is a separate mode.
The product listing describes remote control for boundary settings, correction modes, battery status, and alerts. Remote training supports tone, vibration, or static correction, with a stated range up to 1,000 feet and control for up to three collars.
Important limitation: This product is specified for dogs weighing 18 pounds or more, so it is not a suitable match for dogs below that stated threshold. GPS containment also differs from a transmitter-based circular wireless fence.
PATPET Remote Training Collar

Best for: Owners seeking a remote training collar for dogs within the listed 8–120-pound range. Its modes are beep, vibration, and adjustable static stimulation with 1–16 intensity levels.
The remote has a stated range of 4,000 feet. The receiver is described as IPX7 waterproof, and both the remote and receiver recharge by USB. These features may suit training sessions in outdoor settings where remote communication is useful.
Important limitation: This is a training collar, not a wireless fence or automatic containment system. The listing also says the remote is not waterproof, so it should be kept dry.
HapTop 4500-Foot Training Collar

Best for: Owners of dogs weighing 10–120 pounds who want remote training, including households with two dogs. The dual-channel remote can control up to two dogs and retains each dog’s settings.
Four modes are listed: beep, vibration, safe shock, and shock boost. The static function can be turned off for a no-shock option. The remote range is listed as 4,500 feet, and the receiver collar is described as IPX8 waterproof.
Important limitation: This is a remote training collar rather than a boundary fence. Its stated minimum weight is 10 pounds, so check your dog’s weight before considering it.
Buying Guide: How To Choose A Small Dog Fence Collar
Do you need containment or remote training?
A fence system creates a boundary and responds when a dog approaches or crosses it. A remote training collar lets an owner send a signal manually. They are not interchangeable: PATPET and HapTop are training collars, while MIMOFPET and PetSafe are containment options. The GPS system lists both fence and remote training modes.
Does the product fit your dog’s weight?
Check the stated weight range before buying. The GPS model lists a minimum of 18 pounds, PATPET lists 8–120 pounds, and HapTop lists 10–120 pounds. MIMOFPET is described as designed for small breeds, but the supplied details do not give a specific weight range. The PetSafe details provided also do not state a minimum weight.
What kind of boundary works for your property?
MIMOFPET offers an adjustable distance range and is described as portable. PetSafe uses a transmitter to create circular coverage of up to 1/2 acre. The GPS model uses adjustable radii from 25 to 999 yards. Consider your yard shape and outdoor use; wireless circular boundaries may not match every property layout.
Which correction modes are available?
Compare fence alerts separately from remote training modes. MIMOFPET’s fence mode uses beep and vibration alerts, with no automatic static. Its remote training mode has separate static settings. The GPS, PATPET, and HapTop listings describe tone or beep, vibration, and static options for training. Select settings carefully and follow the product instructions.
Frequently Asked Questions
Is a shock collar fence the same as a remote training collar?
No. A fence system creates an automatic boundary response, while a remote training collar is controlled by an owner. Some products combine both functions, but others provide training only.
Does the MIMOFPET fence automatically deliver static correction?
No. Its listed fence mode uses beep and vibration warnings and does not provide automatic static correction. Static is listed for its separate remote training mode.
Which listed product is specifically described for small breeds?
MIMOFPET is described as designed for small breeds. Its supplied product details do not state a specific minimum weight, so review the full product information for fit.
Can I use the PATPET collar as an automatic fence?
The supplied details describe PATPET as a remote training collar, not an automatic fence system.
What should I verify before buying for a very small dog?
Check the product’s minimum weight, collar fit, containment mode, and correction settings. Do not assume a general dog-training collar is suitable for every small dog.
