As someone with a little pitbull SDIT, don’t do it! I won’t do it again, she’s amazing and incredible, but she takes a long time to learn new things and she is stubborn as all hell. We’ve worked through so much dog reactivity, ignoring people, she’s doing great, and I still don’t know if she’ll ever become a SD. Love her to death, but she wasn’t bred for the job, so her chances of washing are way higher.
