Hello,
I am a volunteer dog trainer at the San Diego Humane Society on Gaines St. As a first choice I would recommend Nan Arthur who was the senior dog trainer at the SDHS for years. She is now a private trainer. Her web site is
www.wholedogtraining.com. The SDHS is also a very good facility and does private consultations for behavior issues just like what you are facing.
Whatever you do PLEASE beware of harsh training methodologies. Using punitive and harsh methods on a terrier WILL back fire on you. There are much more effective and positive methods available in the last 5 years or so.
If you have any questions please feel free to email me directly. I'm at
rparker5@san.rr.com
Sincerely,
Beth Williams
