A dryer is an important purchase for a groomer. There are 3 types of dryer available:
blasters
finishing dryers
combination dryer/blaster
For the start-up groomer, a combination machine will give you the best of both worlds. An established groomer may use a separate blaster and finishing dryer. Regardless of your choice, it is sensible have more than one dryer, in case one should be in service or in need of repair.
