Agree totally with Chelle. The whole process starts with a basic & its important to create a broad foundation & not always stay on schedule.
In a few weeks you should see Douchie begin to put it together, oh that word/sound means I have to do thusly & then get that treat. Then the training may get a bit easier.
I have good results like if teaching sit, in the beginning, when Douchie is 'about' to sit & you can see he's maybe thinking, go ahead & say 'good-boy' or 'yes' whatever but expect him to go on & do the sit with maybe a bit of gentle physical placement/treat.
After he is catching on, you can expect better/quicker responses.
Now with a Bassett, it may not be as much of a problem, but in general at first a dog might actually sit for only a split second & you have to be quick to praise/treat for even that, & in time the length of sit increases.
Always end on a positive, if he is having difficulty with a new lesson, then after that brief session, do something he likes & is good at.
One thing about going to classes is that a 3rd party (instructor) can observe some of the more subtle body language of handler & dog & coach you to emphasize or avoid those specific to you both. In that way dog training is like gymnastics.
