skyhigh,
You really seem grown up at 13 to even think of a vest.
Rocket does not have one yet, so I am not sure of the cost.
It sounds like a great idea brewing in your head, though.
Rocket just started patrol about 3 months ago, she is a well rounded great dog and she is only 15 months old now. And she is certified in tracking, apprehension, and narcotic detection (when she was 12 months old). So she is doing great, and has already taken a good quantity of drugs off the street.
And she has the best personality ever.....
Best Wishes,
Julie.
