Often, I hear "The dog has it, or it does not"
Viper is a Mali that is very fearful, has poor nerves, but is already trained to work in a correctional facility. CM helps him socialize, but leaves me wondering: Would it be fair to keep him working for his original intent? It gets much worse than a skate park in a correctional facility, and this dog does not seem to have the nerves necessary for that work. Seems to me this is just another training and social issue to be worked through.
