I often see suggestions to go to a "good dog trainer" to solve your dog's behavior problems.
fyi A-N-Y-O-N-E can get a biz license, create a website & get into the dog training biz. There are all kinds of classes & certificates that you can obtain over the www or in person & then you can claim yourself "certified" as a dog trainer. It's sort of like going to a week-long Lego course & then claiming you're an architect.
If you're really interested in training I suggest:
--Bridge & Target (google Kayce Cover) for a manual you can download-extremely helpful for communicating w/your dog
--Handbook of Applied Dog Behavior and Training, Vols. 1,2&3
&/or Michael Ellis
videos available on the www.
attend some Ivan or Ellis seminars after watching videos on www
If you still want to see a trainer, watch some of their videos (they should have videos (not just pictures) on their website or YouTube Channel to get an ideo how they train & the results they achieve. They should have examples of puppies & adult dogs.
An excellent example of a training session is on this site right now:
The dog is joyful the handler obviously loves her dog & you can see for yourself the results.
