Here are some great websites to check out. There is lots of good information and/or articles on them.
EXCELLENT article on Dog Psychology 101
Dog Aware - Great information on feeding and health problems!
Dragonfly Training Levels - Wonderful info on training levels to complete and articles on dominance etc.
The Flying Dog Press - Worth reading - He Just Wants to say "Hi""
Clicker Solution Traing Articles
I am not a fan of Cesar Milan of the TV show "The Dog Whisperer". Here are a couple of articles that mirror my thoughts.
Talk Softly and Carry a Carrot or a Big Stick? SPCA article - click on "Whispering About it" under the archive list on the right.
The Anti-Cesar Millan - Ian Dunbar's been succeeding for 25 years
Pack of Lies a NY Times article
If you can't get the above article at the link above, I have copied and pasted it here
I have posted the books as links to Dog Wise or Barnes & Nobles just so you can look at them in further detail. They are just where I usually buy my books. I do not make any money off of the selling of these books.
They are just listed here as books I liked and feel are worth reading.
I do not always agree with all of each authors recommendations in all situations but in general I like their approaches to working with dogs.
For example, Suzanne Clothier does not like head halters and I use one on my dog and absolutely love it and I've seen them work wonderfully on many other dogs.
Any piece of equipment must be used in the correct manner and on the right dog.
I am a strong believer in positive training, as you could probably tell by the book titles.
