Long Probes, Short Probes, and Correct Remote Collar FitMost Tri-Tronics and SportDOG systems come with both long probes and short probes. With the other brands it depends on the unit. We list all units that come with both.
As a general rule, dogs with short coats (English pointers, GSP, brittanys, beagles, hounds) use short probes, while dogs with longer, thicker coats (labs, goldens and Chessies) may need the longer probes.
This can vary depending on the weather conditions and the thickness of the coat or under coat of your dog.
Even with the longest probes installed it may be necessary to thin the dogs coat. You do not have to shave him to bare skin, but inconsistent (unreliable) skin contact will result in inconsistent stimulation.
All ecollars need to be very snug to work. When fit properly, they are tighter than many inexperienced users are comfortable with. If the collar is too loose you have 2 problems -- inconsistent skin contact (see above), and they can rub causing serious skin irritation. The best way to fit an ecollar is high on the neck, just off to one side of the larynx, and very snug. If the collar is fit properly it should not move from this position, even on a very active dog.
