I own a dog in partnership with 3 frinds, one of whom Vanhalla also posts on this board.
You have to be clear from the outset what form this partnership will take, and draw up an agreement of how long it is to last, and what happens when the partnership is disolved.
in our case one of us has an account into which we all pay money as and when needed, and out of this all the dogs expenses are paid. the person with whom the dog lives is reimbursed the cost of his keep.
A freind of mine has a dog in partnership, and to all intents and purposes the dog is hers, she pays for all his keep, and the other person pays nothing. In this case the partner owns the sire and he was her stud fee pups, which she gave to my freind free of charge. If the dog is used for breeding then she will also have to agree as will be required to sign the litter registration form, but I think any stud fees will be kept by my freind(this is the sort of area that needs to be convered in an agreement).
