I wish you good luck. And hopefully your dog will recover soon. Having his leg in a splint seems awful :(

Those jumping spiders are a species on their own :) I remember when my parents bought the house we would live in ( I was seven ), we had a stroll through the abandoned garden. The grass was long and yellow, dried out. With every step you took on that grass, like a hundred little jumping spiders jumped away. Awful. I still remember that :)
