What's the biggest non-essential expenditure that you've made for your dog? Fun Question!?

Probably buying a new house with wooden floors and a fenced yard so that they could safely spend more time outdoors. Other than that, there isn't a grooming tool, toy, collar or leash that we don't own. They're flush with hunting accessories, too: neoprene vests, canvas chest protectors, e-collars, etc. The little one has steps to help her get up into the bed, and the big ones have memory foam dog beds. We, too, upgraded to leather on our last vehicle purchase, to make it easier to clean up after the dogs.
