So yesterday, I gave Vermont Dog Trainers' podcast a try. It was very easy to listen to, and went over topics that I am going through like now (example senior dogs, we have 3). They discuss things that I can relate to, and I am sure other dog owners can relate to as well. Also, if you are a dog trainer, they cover topics that we deal with all the time. I have only listened to a few so far.
I should also mention, the podcast also does interviews with other dog trainers. That happens to be interesting to me, since I am mostly chained to my house or I may get out to see a certain dog trainer at a seminar. Often I don't know of many dog trainers that may be right around me.
