The right invisible-fence collar depends on the transmitter and receiver system you own. The PetSafe Ultralight is best for adding a pet to many PetSafe in-ground systems, while the PetSafe Wireless collar is for PetSafe wireless transmitters only. The Stubborn Dog collar is designed for dogs needing stronger correction options. A replacement strap may fit many existing receivers, but it is not a receiver collar. The GPS model is a separate containment system, not a compatible replacement for a traditional PetSafe fence.

PetSafe Ultralight In-Ground Fence Collar
Best for: Pet owners who need an additional receiver collar for a compatible PetSafe in-ground fence. PetSafe says the collar works with its in-ground systems except YardMax and UltraSmart, making model verification essential before ordering.
The receiver offers a sound-only training mode and four static correction levels. It is waterproof and has a low-battery indicator. The manufacturer describes the collar as an add-a-dog option, so it can suit households adding pets to a supported system.
Limitation: It is not compatible with every PetSafe fence. Avoid this choice if your system is YardMax, UltraSmart, or a wireless model.
PetSafe Wireless Fence Collar
Best for: Owners of a PetSafe Wireless Fence transmitter who need a collar for another pet or a replacement. It adjusts for neck sizes from 6 to 28 inches and is listed for pets weighing 8 pounds and up.
The waterproof collar works with PetSafe Wireless Fence transmitters. Its battery is specified to last one to three months depending on use, and a low-battery indicator alerts owners when replacement is needed. It uses a PetSafe RFA-67D-11 battery.
Limitation: This collar is explicitly not compatible with PetSafe in-ground fences or remote trainers. Choose it only for a supported PetSafe wireless system.
PetSafe Stubborn Dog In-Ground Collar
Best for: Owners of a compatible in-ground fence who need a receiver with a higher correction intensity option. The collar has four adjustable static correction levels, including the highest intensity available in the product’s listed range.
It also provides tone and vibration warnings, which may be useful for training a hearing-impaired dog. The waterproof receiver has a low-battery indicator and uses a 9V alkaline battery.
Limitation: The supplied product details do not name compatible fence models. Check the fence manufacturer’s model compatibility information before choosing this collar; its in-ground design does not establish universal compatibility.
Rhea Rose Replacement Collar Strap
Best for: Owners whose existing training or fence receiver works but whose strap needs replacing. This 3/4-inch strap fits neck sizes from 9 to 26 inches and is described as compatible with most brands and models.
Listed examples include PetSafe UL-250, PUL-250, UL-275V, UL-275M, UL-275D, PUL-275, PIF-275-19, and PRF-275-19, as well as SportDOG SDF-R. The floral pattern offers a different appearance from a plain strap.
Limitation: This is a strap, not a complete receiver collar or fence system. “Most brands” does not guarantee a fit, so compare the receiver’s attachment layout and dimensions before buying.
AIVEYSYA GPS Fence and Training Collar
Best for: Buyers considering GPS-based containment instead of a buried-wire or transmitter-based fence. The product combines GPS fencing and training functions, with app-drawn circular or polygonal boundaries stated to range from 82 to 7,000 feet.
Listed features include beep, vibration, and static modes with adjustable levels, an IP67 waterproof rating, and no subscription fees for app access. The product description says GPS performance is best outdoors with an unobstructed view of the sky.
Limitation: This is not a collar that adds to or replaces the receiver for an existing PetSafe invisible fence. GPS positioning depends on outdoor conditions, so compare the operating approach with your current system before choosing it.
Buying Guide: How to Choose a Compatible Collar
Does the collar match your fence system?
Start with the fence’s brand, system type, and exact model number. In-ground and wireless systems may use different receivers. A collar that fits the same brand is not necessarily compatible with every system from that brand. Check the product’s stated exclusions as well as its supported models.
Do you need a complete receiver or only a strap?
A receiver collar contains the electronics that communicate with the fence. A replacement strap only holds an existing receiver. If your receiver is missing or incompatible, a strap alone will not make a fence work. Check whether the product listing includes a receiver before ordering.
What correction and warning options are appropriate?
Compare the available sound, vibration, and static settings with your training needs and the fence manufacturer’s instructions. The Ultralight offers sound-only mode and four static levels; the Stubborn Dog model lists tone, vibration, and four static levels. Follow the system’s training guidance and use the least intense setting appropriate for your dog.
What fit and maintenance details matter?
Measure your dog’s neck and compare it with the stated range. Also check collar width, battery type, waterproof description, and low-battery alerts. For the PetSafe Wireless collar, confirm that the required RFA-67D-11 battery suits your maintenance preferences.
Frequently Asked Questions
Can any PetSafe collar work with any PetSafe invisible fence?
No. The wireless collar listed here works with PetSafe Wireless Fence transmitters but not PetSafe in-ground fences. The Ultralight in-ground collar excludes YardMax and UltraSmart systems. Verify the exact model before buying.
Can I use a replacement strap as a fence collar?
No. A replacement strap holds a compatible receiver but does not contain the receiver electronics needed to communicate with a fence.
Is the GPS collar compatible with a traditional invisible fence?
No compatibility with traditional fence transmitters is listed. The GPS model is a separate containment and training system.
How can I check compatibility before ordering?
Find the model number on the fence transmitter or receiver, then compare it with the collar’s compatibility list. If the model is not listed, confirm compatibility with the manufacturer before purchase.
