ADMIN – Hi Sean,

The twisted wire is used in some layouts to join the loop to the
transmitter. This twisted section is not active and will not correct
the dog if they go over it. For full details on the twisted wire, see
here.

I would like to get your opinion. I live in the country so there will be no interferance with neighboring systems. I have a nine pound chihuahua. I just want to protect him from roaming to the road. I am wondering which system would be best. The petsafe little dog or the perimeter technologies. And which collar would be the best fit? Thank you so much for your informative web site!

ADMIN – Hi Nikki,

With a dog under 12lb, I prefer to use the PetSafe Little Dog. The size of the collar will be fine on either. But, the correction levels on the PetSafe are lower and more appropriate for a small dog. The Perimeter is a good system, but everything but the lowest correction level is going to be inappropriate for your dog, and even that lowest level may be too much.

ADMIN – Hi Allison

With a dog under twelve pounds, they will be happier with the PetSafe Little Dog. Although it has a nice small collar, the correction levels on the Perimeter are set too high for an eight pound dog.

ADMIN – Hi Adriana,

The Perimeter Ultra collar is indeed waterproof. The Perimeter and the SportDog SDF-100 are generally considered to have the best waterproofing.

ADMIN – Hi Liz,

If you set them at two different frequencies, there should be no interference between the two systems. But, the frequencies are close, so you could get some beeping (but no correction) with the signal from System A accidental getting detected by Collar B. This would be very confusing for the dogs, so I would avoid doing this.

One idea, would be for you to do one big boundary around both yards. I am not sure if that configuration makes sense for your situation, but that would let the two dogs play in both yards.

ADMIN – Hi Sharon,

The Perimeter Technologies inground is a really good system. The reason it is not so prominent as say the Innotek’s and the PetSafe is that the price is a bit on the high side and the unit is saddled with a proprietary battery. For the same price you can get say an Innotek IUC-2100 and have a similar system that is rechargeable.

The two really strong points are the collar and the ability to switch frequencies. The collar is really small and light! The system itself can work on different frequencies that you can adjust at the base station. This makes it a great choice where the neighbors have a system and you could get interference. Most of the time, you can just use a different frequency and avoid the interference issues.

Thanks!

ADMIN – Hi Nichole,

if you use any of the ultra models (Perimeter ultra or Perimeter ultra deluxe) you can have independant correction levels that you could use with your Beagle and Lab.
