Most dog groomers careers last just 10 years. It is physically demanding, and grooming 5, 20# dogs a day you have physically moved 1 TON of weight usually by noon. My back, shoulders, and wrists are shot.
Pet owners out there, do your research, observe, ask for references, take the time to find a groomer like you would finding a doctor for your child. Even then accidents can and will happen.
1) Don't leave them tied up anywhere, bathtub, or table they WILL hang themselves or fall (I have caught a few unattended dogs falling off tables at dog shows), and no choke chains, or leashes in kennels, again, they will figure out a way to hurt themselves.2) Don't leave a dog in a dryer cage, or with a force air dryer hooked to the kennel running unattended ever, even ambient air dryers use surrounding air be that 60 degrees or 90 degrees to dry the dog.3) Be honest with the owner, I don't know your dog, it doesn't know me so give me at least 4 hours to do the dog. Do new dogs when you have plenty of time. Take your time and don't get distracted that's when accidents happen.
