I have tried this, as well as soaking orange or lemon peels in oil (any type you use for cooking) for a week or so, then spreading it around my garden. It does seem to help as long as it does not dry out or rain excessively. I've used completely cooled wood ashes for other types of nuisance animals, but the best solution I've found for everything is having someone let my dog out at unpredictable times of the day.
My arugula reseeds itself, no need to plant it
Dandelion does not thrive in sandy soil
I could have gotten at least 4, but I wanted to live to see the next day, so I only took 2 and regifted one of them
let’s hope late frost doesn’t kill the bloom as it did last year 
My outdoor lettuce is like that, it bolts almost as soon as it comes up - which is why I’m planting some indoors. It may eventually go outdoors, along with the rest of the greens, but hopefully I’m not overcharging it with the grow lights again and I’ll actually get a couple salads off it before it gets to that point. I managed it two years ago but didn’t manage to duplicate that success last year.My arugula reseeds itself, no need to plant it
Wow, I never imagined dandelions being difficult. They certainly do better and grow bigger in soft loamy soils. I dry the harvested leaf in a cupboard and use them like dried parsley. The chickens also really enjoy a sprinkling of them in their seed. I used to do the same for my little budgie when the commercial seed stopped adding greens to their mix. Dandelions are very high in vitamin C.
I've used pepper, and a dog or two also helps
