About.com is a great website. Especially interesting to HSRC members is their information on dogs and cats. Listed below are the starting sites for endless information on dogs or cats.
There are courses you can sign up for, such as one I took on kittens. You get a weekly session for 6 weeks or so.
There are also newsletters on pets that are free e-mail guides.
The following are some examples of the type of information available: FAQ's; responsible ownership; dog care basics; working dogs; pet loss; training and behavior; and so on. I have found the information very helpful. Each session refers you to other sites and sources of information. There are also many photos and a pet of the week.
