UltraMax SmartReceiver - Maximum Power for the Most Determined Dog

If your dog has a more determined mindset, the UltraMax® is the collar for you. Like our other collars, the UltraMax offers many adjustable corrections. With a Stopper™ option & Anti Run-Through technology, the UltraMax is extremely convincing - the most effective dog fence collar available to keep your pets safe.


The Dog Fence Experts at Pet Stop designed the UltraMax with your dog’s safety in mind.  Though relatively lightweight, this heavy duty receiver has a range of programmability, including progressive high-level corrections. The UltraMax receiver collar boasts all these features:


Fast Reaction Time - No dog fence collar reacts faster than Pet Stop

Pet Stop Smart Receiver collars react faster than any other brand of receiver. While the EcoLite Receiver reacts in just 80 milliseconds, the UltraMax® is not far behind. Don’t be fooled by fancy names or competitive claims. Only Pet Stop is engineered to be the safest and fastest receiver available.


SafetyStop® - Prevents continuous corrections

If your pet ever gets trapped in the signal field, only Pet Stop receivers will shut off and remain off until your pet is safely out. Other products offer a similar feature, but none are as comprehensive as the Pet Stop version.


Correction Modes — Options for different situations

The UltraMax offers different modes of stimulation, giving you more flexibility to contain the more challenging dog:


► Progressive Mode used after training to advance the correction level automatically

► Standard Mode Offers 32 static correction levels


Your dealer will help you select the mode and settings best suited for your pet.

Stopper® Anti-Run Through Technology - Effectively addresses escape attempts

For difficult to convince pets, the UltraMax is capable of more powerful corrections than any other receiver. The Stopper feature can extend those corrections well past the actual boundary with three timed settings to be sure that the most stubborn dog learns to stay safe at home. 


Flash Alert™ Low Battery Light - Warns you when your battery gets weak

Flashes brightly so you know when the receiver battery gets weak, giving a 3-4 day warning. Knowing when to change the battery, or recharge it in rechargeable models, is a critical requirement for safe Pet-containment. The Pet Stop exclusive FlashAlert will remind you to replace or recharge the battery before your pet gets loose. This is a true battery-monitoring system — not a timed reminder like you might find in other brands.


Tri-Scann™ Omni Directional Antenna - Eliminates blind spots

Our receivers have three antenna with a full 360 degrees of detection. There are no blind spots or “holes” where the collar is not receiving a signal. Other receivers require the pet’s head to be perfectly straight and level when approaching the fence signal. Pet Stop is the first to offer a three-antenna receiver, which provides your pet with a full 360-degree reception of the signal, regardless of the collar position.


Comfort Contacts® and Gentle Spring Contacts

Our patented Comfort Contact collar probes come in three sizes and are made from a specially designed rubber that is more comfortable on your pet’s neck, while still delivering corrections when needed. Gentle Spring Contact posts also come in three sizes and are retractable, made to maintain skin contact no matter how thick your dog's coat - without putting undue pressure on the neck.  Including our four sizes of stainless steel posts, that's ten different contact post variations designed to suit any pet.  Compare that to the two sizes offered by competitors and you'll see that Pet Stop customizes pet containment better than anyone. 


Choice of Colors

From fire engine red to Kelly green, Pet Stop has the right color for your pets. All of our receivers come with a large choice of collar colors.  Shop for nylon collars


Replaceable Batteries

Powered by lithium technology and selected for a wide range of weather durability, Pet Stop dog fence batteries outperform other pet fencing batteries, including lithium coin cells.  Shop for dog fence batteries


Be sure to fit your pet fence collar properly so your Pet Stop dog fence will work as designed. The best fit depends on which contact posts you have, too. Your Pet Stop representatives can help you make sure your receiver collar fits correctly.
