I have a rescued dog that had been rescued because the orig. owners did not want to chase her anymore! After 3 years of doing absolutely everything in our power to contain her within a yard we decided on the wireless containment system. One that delivers "pulse-rate" charges (intermittent, short charges) while the dog is out of range. Please note however,
this was used as a last resort.Her running became a health and wellbeing issue when I found her stranded on a rock in the middle of a fast moving river adjacent to our home. We had tried everything previous to this (this dog even chewed right through several steel tie outs and understand this is a dog who was never left outside for long periods of time). This system was able to train her to stay in the yard - but keep in mind it is i
mparitive that you follow all instructions carefully as if you do not it can have deadly results.
I do have a second dog who does not run off - sometimes he wanders but I would
never think of having him on this system because he is "containable" and has an exciteable sort of temperment and would find himself outside of the designated area often despite training. This is not a tool for a dog who just wanders off occasionally - and only should be used if all other methods have been exhausted. If it must be used in that case, I urge the use of the wireless "pulse-rate" system as the old systems deliver a constant charge that could kill the dog (systems which I think are very inhumane) - also the wireless system continues intermittent shocks until the dog comes back into range - so ther is no issue with the dog wanting to come back. My every diligent dog only got shocked once and she is a dog I thought would even find a way to beat this system! I do reccommend as does the manufacturer that you not leave the collar on all the time. I remove hers at night (I must leave it on the rest of the time as she will run out of any open door).
PS- sorry if I misspelled anything - am burning a pizza while I write!
