Contain & Train SDF-CT Overview

Summary: Good Long Range System with Added Features

The long awaited Contain + Train™ by SportDOG offers dog owners an all-in-one solution to training and containment needs. The system combines the best features of the well-loved SDF – 100A electric dog fence for up to 100 acres with the capabilities of the FieldTrainer® 425 (SD-425,). The Contain + Train™, is the best value for your money and the ultimate solution for dogs that require correction for boundary containment as well as training protocol. This is a dream come true for owners of working and hunting dogs.

Thoughtfully Designed Collar

The one inch wide waterproofed collar features numerous improvements over the predecessors. Easily adjustable buckle, two sets of contact probes included to allow you to customize to your dog’s coat length and a rechargeable receiver that lasts up to 168 hours on a single charge even when used in training and containment mode. The collar includes a display with lighted icons to help you easily set up the receiver for the desired mode

100-Acre Capacity

The basic system includes 1,000 feet of boundary wire (sufficient to cover an acres), twice the standard amount provided with other dog fencing system. The technology behind the Contain + Train™ makes it the most reliable and most expandable fence. SportDOG Contain & Train has been the go-to electric dog fence solution for most large properties around the world.

Safety Features That Matter

The system features a self diagnostics alert that lets you know when there are problems with the wire, the transmitter features anti-lightning protection and the collar is programed with an anti-linger feature to prevent the collar from running out of battery in the warning zone.

Ample Compatibility

The hand held remote is compatible with the following training collars:SD-425, SD-425S, SD-425CAMO, SD-825, SD-1225, SD-1825, SD-1825CAMO, SD-1875, SD-2525, and SD-3225. However, these collars will NOT work for containment with this system. The following fence collars will work with the transmitter for containment but not with the remote for training purposes: PIG19-11042, PRF-275-19, PUL-275, PCF-275-19, PIG00-13737, SDF-R.

Dog Capacity Limitations

The Contain + Train™ only expands to a maximum of three dogs on the one training remote. Also due to the design and bulkiness of the collars we don’t recommend it for micro breeds or dogs under 30 pounds. For containment only, this system will allow for an unlimited number of dogs.

SportDog Contain & Train SDF-CT Collar

Many Potential Training & Containment Options For Ultimate Customization

In containment mode the system offers seven levels of static stimulation, vibration and audible tone.
In training mode you have seven levels of stimulation in three different strengths each as well as audible tone and vibration. You can customize the feedback to best need the training needs of your dog

Bulky Heavy Collar

The Contain & Train collar is one of the biggest and heaviest wire dog fence collars. The size of the collar makes it completely unsuitable for dogs under 30lbs. If you have smaller dogs, use the PetSafe Deluxe Collar PUL-275 for dogs over 12lbs, or the PetSafe Little Dog for dogs under 12 lbs.

Small Collar Charger

The collar uses a quick plug in charger instead of a a permanent base-style charger. While convenient when traveling this type of charger may be easy to misplace or damage.

Superior Waterproofing & Durability

Collar Receiver is waterproof and submersible to 10 feet . The texture is rubberized for easy grip and the unit is super easy to wipe clean. While quicksnap closures are far more convenient the metal buckle featured in this collar is far more adjustable and potentially more durable

Rechargeable Lithium Battery

The lithium-ion battery gives you the peace of mind of never running out of charge. The battery charges quickly (2 hours for a full charge) and can last over 150 hours in dual mode and far more when set to containment mode only.

Easy to Read Lighted Collar Display

No more guessing. The icon based lighted display tells you exactly which setting you selected. The collar also features lighted alerts to let you know when the battery is running low.

Remote Control Unit

The remote transmitter included with the system is sturdy and easy to operate offering utmost portability and comfort in the hand. 5.30 inches long and 1.70 inches wide the unit easily fits in your pocket. The remote also comes with a very durable lanyard to hang from your neck when pockets are not an option.

The remote unit include a lithium-ion battery that charges in only two hours and offers up to 70 hours of operation between charges. This feature saves you money and gives you the peace of mind of always having a charged remote.

The remote can adjust the level of feedback to seven different strengths each one featuring low, medium and high range. In addition the remote also allows you to active vibration and tone mode.

DryTek® technology makes this remote waterproof and submersible to 25 feet in addition the charging jack has a cover that protect the entry point from water and humid exposure.

Contain & Train SDF-CT Transmitter


The transmitter is the very heart of the containment system. The unit is sturdy and offers simplicity and durability. The lateral lighted display will alert you of loop issues allowing you to quickly address any potential problems. The unit will also allow you to quickly adjust boundary width both for audible/vibration warning as well as correction.

Largest Capacity in The Market

No other system even gets close to this. The Contain + Train can cover up to 100 acres with additional wire. This fence will allow you to maximize your property giving your dogs maximum roaming area.

Adjustable Boundary Only

The dial on the transmitter allows you to quickly adjust the warning and stimulation width. Customizing the width of your boundary allows you to address issues with stubborn dogs and also to reduce the width when your space does not permit for a wide boundary.

However, the boundary correction and warning distance cannot be adjusted independently and instead move together.

No Battery Backup

Our perfect system would have redundancy to ensure power continuity. The Contain + Train does not. If you have a power outage, down goes your barrier until the power is back. Consider using a battery backup if you are in a rural area with frequent outages.

Contain & Train SDF-CT Wire and Accessories
Dog Fence Wire Gauges

Boundary Wire & Acessories

Tester Tool

The Contain & Train system includes a basic tester tool for checking whether the collar is working (without you needing to find a patsy to shock).

Professional Gauge Wire Available

The basic system includes 20 gauge wire, but can be upgraded to 18, 16, and 14 gauge wire. Thicker wires like  16 and 14 gauge are considered professional grade and is what you would see on an Invisible Fence installation. With professional grade, the copper wire and protective insulation are both four times thicker and stronger than the standard wire. This makes the wire stronger and more durable and therefore less likely to break.

For small installations, upgrading the wire is a modest investment and will dramatically reduces the likelihood of you needing to hunt for wire breaks.

For large installations, the thicker gauges of wire are useful because of their superior transmission characteristics. However, the additional cost imposed by the thicker wire can quickly add up.

1,000 feet of wire, 100 Flags and 2 Splices

The SportDOG Contain & Train includes double the usual amount of boundary wire, 1,000 feet of 20 gauge. This allows you contain 1 acre. Additional boundary wire is available for purchase, with the system capable of powering over 9,000 feet of wire.

The wire is direct burial rated, so holds up better in the ground than standard electrical wire. The boundary wire is surrounded by a PET jacket. This protects the wire against the elements better than standard PVC coated electrical wire that will tend to rot, particularly in acidic soils.

The standard Contain & Train by SportDOG Fence kit includes 100 flags to mark the boundary line during training. It also includes 2 wire splices. Additional flags and splices are available through our online store.

We just bought a house that already has the wire installed, can I buy just the transmitter and collar for the contain and train unit? We have an 11 week old lab, would it work for him?

ADMIN – Hi Mike. As long as the wire is still in good shape, you should be able to use it. However, we do not recommend beginning fence training for any dogs until they have reached at least 6 months of age.

Chris thieman June 4, 2018 at 3:32 pm

Is my sport dog 425 compatible with regular sport dog underground fencing

ADMIN – HI Chris. No, the SportDOG training collars are NOT compatible with the containment transmitter. However, they would work with the remote that comes with the Contain and Train system.

Kit Carlson May 30, 2018 at 11:48 am

I take my dog hiking frequently but at times she will run off after squirrels. What is the range for the “training” component of the collar outside the containment area?

ADMIN – Hi Kit. The range on the remote is up to 500 yards, per SportDOG.

TAMMY FREDRICKSON March 29, 2018 at 4:45 pm




ADMIN – Hi Tammy. For a single sided boundary loop, you will want a traditional system such as the PetSafe In-Ground Fence PIG00-13661: PetSafe In-Ground Fence PIG00-13661 is cross collar compatible and works with MOST PetSafe collars but DOES NOT WORK WITH THE YARDMAX COLLAR. This system would allow you to use the PetSafe Deluxe Collar (Standard correction levels, good for dogs between 5 and 90 pounds, $69.95), Stubborn (for large dogs or dogs that need more corrective power that are over 40 pounds, $79.95), PetSafe Rechargeable In-Ground Fence Receiver (A rechargeable collar with 4 correction levels ($119.95), Elite Little Dog (for dogs under 10 pounds, $99.95), Cat or SportDog (most rugged and waterproof collar and is meant for dogs that are hunting or farm dogs ($99.95)) collars. All of these collars are battery operated and have indicators to let you know when the battery needs to be changed. This system only operates in traditional mode and does not offer the run through deterrent. This is a good, reliable system that will work well in most configurations. This system will support up to 25 acres of wire.
