We could devote an entire page to this one. First, let's look at the dogs you'll be grooming during a given day. You've got 110-lb. golden retrievers that would much rather jump off your grooming table than stand on it. You've also got ancient German shepherds and mastiffs that can barely stand up, much less stand still on a grooming table. Unless you're lucky enough to have a hydraulic table you can raise and lower, you'll have to find a way to lift these huge beasts on the table without totally throwing out your back. Then you've got to hold them still—and sometimes hold them up—while you groom them. Oh, and did we mention they'll need to get down?
At the other end of the spectrum, you've got the terrible terriers. Although some small terriers have pleasant dispositions and are just a little feisty, others wake up looking for a fight. If they can't find another dog to bully, they're happy to gnaw on a groomer's finger. True story.
Let's assume you're able to outsmart the dogs, or at least they don't send you to the hospital. You're still at the mercy of your grooming tools. Although your clipper blades are relatively innocuous, we can't say the same for your grooming scissors, which are REALLY SHARP! That's why they work so well. Unfortunately, dogs don't always hold still while you're scissoring faces and feet, which means you could slice a finger or palm before you know it. Even if you manage not to bleed on the freshly washed dog, you'll still have to wipe the collateral damage off yourself.
Finally, remember all those repetitive clipping and scissoring movements can take their toll on your arms, wrists, and fingers. If you're making decent money by cranking out multiple dogs each day, the carpal tunnel might be a bit easier to take. Your clients might also toss you a few more tips if you flash your wrist brace at them.
