Kate that's awful
The training curses I've been on have been really enjoyable for both puppies/dogs and owners!
If there's not another course nearby you might like to have a look at
thisIt's cheap, and quite simple but effective - so long as your dog likes food/treats
The puppy course Minnie and I went to used them. It didn't work for her as she's just not food-orientated, so one treat fine, but not interested after that! Fortunately I'd been on enough training courses before to work withe her anyway, plus she was very trainable, but it's much better really to be with the other dogs.
