The IUC-5225 Receiver Collar is Out of Stock until 6.28.2010. If you need a collar that is compatible with the fence, the IUC-4225 collar is in stock, and from the MuttFence.com store comes with 2-Day Shipping. IUC-4225 collar will only work with the fence and will not respond to the remote control.

The IUC-4225 Receiver collar is compatible with both the IUC-4100 & IUC-5100 fences. (Note: this collar does not work with the IUC-5100 remote control.)

Each of these products come with one collar, the IUC-4225 for the IUC-4100 Ultrasmart Fence, and the IUC-5225 for the IUC-5100 Ultrasmart Contain ‘N’ Train. The IUC-4225 will work as a fence collar only on both systems, and the IUC-5225 will work with both the fence and the remote.

So, why would you buy one over the other?

• I want to add a dog to my Ultrasmart IUC-5100 Contain ‘N’ Train for the fence only
  You only need to get the IUC-4225 collar
• I want to add a dog to my IUC-5100 Ultrasmart Contain ‘N’ Train for both the fence and the remote trainer
  The collar you need is the IUC-5225
• I want to add a dog to my IUC-4100 Ultrasmart Fencing System
  An IUC-4225 collar is perfect

In a nutshell, if you have an IUC-5100 Ultrasmart Contain ‘N’ Train, you can add a dog just to the fence with the IUC-4225 Ultrasmart Collar, or to the fence and trainer with the IUC-5225 Ultrasmart Collar. FYI: The IUC-5100 has a two dog capacity for the remote trainer.

If you have an IUC-4100 Ultrasmart Pet Fencing System, you should only purchase an IUC-4225 Collar. FYI: The IUC-5225 would work with the fence, but it would additional cost for no benefit over the IUC-4225.

The IUC 5225 Collar has both Ultrasmart Fence and Remote Training Capability

The IUC-4225 is Fully Compatible with all Ultrasmart Fences, but has no Remote Training

How many dogs can I add to the IUC-5100?

Answer:

As you know, the IUC-5100 is a combined fence and trainer – which is why it is called a Contain ‘N’ Train system. The trainer is capable of handling two dogs. The kit comes with one IUC-5225 Ultrasmart Receiver Collar and extra collars are available.

To add dogs to the fence, you do not need the remote training feature. For this purpose, the number of dogs is essentially unlimited. To add dogs to the fence only, you still need an Ultrasmart Collar, and the IUC-4225 Ultrasmart Receiver Collar is perfect.
