What is the light on the transmitter?

The status light on the transmitter lets you know if the transmitter is turned on. When using a boundary wire with the MB-2, the status light glows green only when there is a continuous signal loop. See Owner’s Guide for additional information. Note: The green light may be steady green or blinking green. This depends on the frequency setting of the transmitter.

How do I increase and decrease the signal range (the distance the signal radiates from the transmitter) to make the “off-limits” avoidance zone area larger or smaller?

On the back of the transmitter, there is a signal range knob. Turn the knob toward the ‘Max’ to increase the signal range. This increases the size of the signal field. Turn the knob toward the ‘Min’ to decrease the signal range. This decreases the size of the signal field.

Do I need separate collars for inside and outside?

You do not need separate collars. Use the same collar inside and outside.

How large can I make the “off-limits” area?

The MB-2 can be used with up to 500 ft of wire to protect a large area or create multiple “off limits” zones. When used wirelessly, the MB-2 can be adjusted up to a maximum of 13 feet in diameter (6.5 feet in all directions from the transmitter).

Can I use the MB-2 outdoors?

No, the MB-2 is designed for indoor use only. If you are looking for a portable pet fence that can be used outdoors, check out our MB-1 Indoor/Outdoor Wireless Dog Fence. Or if you are looking for a pet fence to give your dog or cat freedom in your yard, check out our wired underground Outdoor Hidden Fences. Important: Do not set the transmitter on or near large metal objects.

Not All Rules Are Meant to Be Broken

The MB-2 is our most flexible indoor boundary solution. Its transmitter works with or without a boundary wire to keep your pet(s) safe and out of trouble. The MB-2 is compatible with all DogWatch FM receivers, so if you already have an outdoor hidden fence, you can use the same collar indoors and outdoors!

You can install the MB-2 with up to 500ft wire to protect a large defined indoor area (such as a dining room or second floor). Or you can use it without a wire for greater flexibility to protect smaller areas (such as kitchen counters or litter boxes). Used wirelessly, the MB-2 can protect an area up to 13 feet in diameter (6 1/2 feet from center).

 Trustindex verifies that the original source of the review is Google. Troy is fantastic. He came in and assisted with the set up. A full tutorial for me and family. Afterwards, he has taken my calls on stupid questions whenever they come up (a battery needed to get changed out today on a Sunday for instance, and Troy texted me back right away). Also the product is tip top. Highly recommended!

i've had a dog for the last six years who is all "hound" And luckily, the DogWatch vibrate E collar has saved her life more than once. She finds no discomfort from it because she knows that when she comes back to me she gets positive rewards in the form of treats. Due to the fact that she is a hound, it's a natural instinct for her to to chase the squirrels and the deer, etc. The collar is a way to keep her safe and happy! Troy, who is one of the managers of the company has always been there for me and my dog Poppy for any questions I've ever had or for any needs that I've had in dealing with the DogWatch collar

Hershey is our 4-year-old dog, and for the first two years he never hopped our fence. But in the past two years it became completely out of control — he would leap over our 5 ft redwood storybook fence like it was nothing. As a mom of three young kids, constantly chasing him down and finding him was exhausting. We tried so many solutions — even hiring a specialized dog trainer. Other barrier solutions made our yard look like a prison yard, and other invisible fence companies couldn’t figure out the closed-loop circuit, charged twice as much (or more). A new redwood fence…quoted tens of thousands of dollars. Then Troy came.

He was on time, professional, and figured out what others said couldn’t be done. The training was thorough and I couldn’t believe how quickly we got results. Hershey, who had been anxious and obsessed with escape, suddenly became calm, relaxed, and more connected with the family. Now he happily sunbathes, runs free, and even lounges peacefully with our chickens — without that wild, frantic look in his eyes.

Troy is efficient, knowledgeable, and always available for questions. If you’re struggling with an escape artist dog, Troy is the one to call. We couldn’t be happier.

 Trustindex verifies that the original source of the review is Google. Troy is just the best. Easy to work with, helpful in problem solving, super knowledge, cares about the dogs and is just overall a genuinely good human. So happy we made the decision to invest in an invisible fence and work with the company.

Troy and his team are fantastic. Clear about the process, professional at all times, and super friendly. He worked through some installation issues (on our end), always with a smile. He trained Chase and me! His prices were fair. The process was quick. He's a delight....and he brings you a gift at the end of the process. I wouldn't use anyone else!!

 Trustindex verifies that the original source of the review is Google. Troy is a very competent and skilled person and truly enjoys his job and dogs. He installed a pretty significant system on our property years ago, and it has hardly needed repairs (typically due to chewing vermin or tree roots). He has been with me now for almost nine years and several new dogs (we have four total now). He is a credit to his industry!

 Trustindex verifies that the original source of the review is Google. We live in a semi-rural hilly woodsy area. We had a young pup who was visiting our neighbors house.  He’d get into food their and play with their dogs and was getting all sorts of positive feedback for running off.  Troy worked with us to fence the premiere of our home in a challenging environment and supply us with other tools to keep our young dog under control.   It wasn’t cheap - but it worked and Troy was great.

You Asked, We Answered

DogWatch Indoor Pet Fences emit a radio signal that is detected by the receiver collar worn by your pet—the same way the outdoor hidden fence systems work. As your pet approaches the signal field (initially marked with a series of flags to help your pet identify the area), the receiver collar begins to emit an audible (or vibration) warning beep. If your pet goes beyond the warning zone, the warning is quickly followed by a ‘correction’— a mild electrical stimulation from the receiver collar. With proper training, your pet will quickly learn to stay away from areas that he associates with the warning.
