Who would have thought having thousands of tiny hairs blasting everywhere - as well as the general dander and dirt that comes off dogs - would be so damaging to your lungs? Well it is, obviously. Surprisingly, its not just what comes off the dogs that can give you a cough like a 30-a-day smoker with asthma, its also the numerous sprays, shampoos, and other grooming products that cause problems. Wearing masks can help, but theyre not 100% effective. As well as being bit, this is another real hazard of the job. So remember people, always tip your dog groomer, they have to endure a lot.
