A machine that take all the loose hair from a dog or dog and collects it. Must be effective. Great for pet friendly hotels. Dog and cat is shedding too much hair.

Pet goes into an enclosure with its head sticking out and turn on the vacuum for 15 minutes. The amount of suction should suck all the loose hair out of the dog for collection.

Optionally, water jets could also do the same thing while also rinse cleaning the dog.
