Age for Prong?

[Ucdcrush]

I am using one on a 6 month old, high energy puppy. Her biggest problem was losing focus when walking and sometimes forging ahead while sniffing, or at worst, veering off towards a bird. The prong collar has really helped her focus, and I've only administered small corrections with it.

Keep in mind like everything else, there are levels of correction with a prong collar. You're not going to yank the dog around with it, just give it the level of correction it needs to lose the focus on the car/bird/etc. and get the focus back on walking next to you.
