hi there
how wonderful !

Well, my idea is geared more toward having a business that just spoils pets.
Most working 'metro' people will pay top dollar for their pet to be well cared for while they work/play.
Maybe start MORE than just a dog walking service, it can be called something creative like - BEST FRIEND VISTIOR, HUGS DAILY.
Something where you are giving love and attention to ( in my opinion) neglected animals. Where you play with them, walk them, even a light groom or spoil with a treat daily. Like a big dose of love. ( for 25 mins, it will cost $25)- part of your costs can be donated to shelters etc, so the people feel like they are helping more than their own dog, and you will too!
something creative!
My other idea is for an indoor doggie park.
Like a skate rink, where in the middle is the dog park, and on the side it is a coffee bar, computer place, etc, and the dogs mingle with eachother. That is huge and needs huge backing. but i think it would be so cool!
