Question

My friend, her brother, and I are going to start a dog walking business, and we don't know how much to charge. What would you think is an agreeable price for these--

Below is: the size-- example of dog

Extra Large-- Great Danes

Large-- Golden Retriever

Medium-- Lab, poodle, Cocker spaniel

Small-- Reg. Yorkie

Extra Small-- Miniature, teacup, or runt of the litter of any type.

Answer 1

how about  making it more simple

long walk 1hour- £10

medium walk half an hour- £5

small walk- £3.50

(somthing like that but better) because its a bit confusing with all those sizes of dogs!! lol hope i helped!! :D x
