You should do what we were told by the local cable company... this is a quote from our actual flyer..

"Remove the dog from the backyard area, or no service will be provided..."

Later on down the deal..

Any dogs, thought to be hostile by the tech's will be pepper spray'd, and detained..

I have only had to pepper spray a dog twice in my two yrs on the job as a cable contractor, and I always thought it was a stupid thing to have in my tool belt until that stupid dog thought my skiny leg and thank god for lineman's boots.. rotfl Dog got a face full of pepper spray, and i got three stiches above the knee and then 15 on the 2nd and last one (wasnt wearing my knee highs...).. I quit after that..

See it could be worse.. well at least i hope you got no stiches or shots, those things really hurt...
