Innotek Smart Dog-2100 Collar

Model: SD-2225

Availability : Out of stock


No Hassle 30-Day Returns
Upgraded Warranty


The Innotek SD-2225 is the Innotek collar used with the SD-2100 or SD-2200 in-ground fence systems. 

The collar is rechargeable and charges atop the transmitter for your unit. The battery takes about 8 hours to charge and does produce an audible hum as it charges. It holds it's charge for roughly a month.

The clunky receiver box is mounted on a blue nylon collar with a reflective strip for nighttime visibility. The collar is durable and completely waterproof.

The collar is capable of 3 progressive correction level settings, but because they are set at the transmitter level individual correction levels are not possible and all collars on the system will be subject to the same correction.

Any number of extra collars may be added to the SD-2100 or SD-2200 systems.

The Innotek SD-2225 extra collar is compatible with the Innotek SD-2100 and SD-2200 pet containment systems and allows you to add any number of dogs to your current fence (each with their own collar).

  1. All the dogs have one Review by Mary DifFebo - Vineland, NJ

    I ordered three of these to go with my Innotek Smart Dog system. I have 3 adult dogs and a puppy (25 pounds already) and this works for all of them. They have gotten wet and we have had no problem with them at all. Love that they are rechargeable. The lifetime warranty lets me breathe easy. (Posted on 2/15/2013)

  2. Hooray for collars Review by carry

    I love the fact that this collar is rechargeable and has 3 progressive correction levels along with a limited lifetime warranty. Not to mention the waterproof feature and value for money in terms of overall quality. This is truly a one of a kind deal.

  3. Innotek collars! Review by Sonya

    Just got two Innotek collars and they work wonderfully! They are also rechargeable, waterproof, and come with a limited lifetime warranty. A very good decision indeed!

  4. Cali Dog Owner Review by Jerry

    - Hello, my name is Jerry. I wanted to take a sec to say that I really enjoy the service that FlexPetz offers. I already had the Innotek SD 2100 from my first purchase (works great by the way) but just needed an extra collar. Once again they delivered just what they said they would. The extra collar is rechargeable, it has a limited lifetime warranty, and it’s waterproof! I am very glad to have found this website!.

November 05, 2014

i have a sd 2100 in ground fencing and have a Gordon setter and pointer with the collars that came with unit ,i would like to know if i could use the same collar on another dog we have that is 28 lbs , or do they make a smaller unit for small dogs.



The Innotek Smart Dog-2100 Collar Model: SD-2225 will be a great fit for a 28 lb dog. This collar is the only collar that is compatible with this system.
