I learned a few days ago that Spica, my lovable-but-not-too-bright younger Doberman, has damaged her ACL. This isn’t really a surprise; Spica is a career runner who chases squirrels up and down the fenceline and spins in circles barking at them for about six hours each day, so her legs are under constant strain. In addition to the dog’s confinement and treatment (and her owner’s possible loss of sanity, living with a dog who isn’t allowed to run for six weeks!), this injury means that we’re likely to be seeing more of our veterinarian than usual.
