Dog tries to tell owner? (dog training tip)

A very cute and smart dog, spent 3 months trying to tell his owner that he wants to.. (you’ll have to watch the video) If you’d like to support my channel, please click the LIKE button, and subscribe. THANKS

I am thinking about doing a little dog training. What can anyone tell me about their experiences?

I have trained my own dogs for hunt tests, which are similar to field trials. Anyway, I have been thinking about placing some ads to see if I can get a few customers for basic obedience. At this time I have not attended any formal training other than some videos and group training sessions. Has anyone tried to do something like this part time? Thanks.
