Pet leasing is the practice of leasing a pet, usually a dog, to a customer on a contract basis. The practice is controversial, because some customers believed they were taking out loans to buy a pet when, in fact, they were only leasing an animal that could be repossessed by the lender in the event that payments were not kept up.The process of leasing a pet typically starts in a retail pet store, but the loan is made by a third-party contractor. The revenue model for pet leasing is the same as car leasing. The borrower enters a contract, typically for two years, and agrees to monthly payments. The lender typically requires proof of income, which may be as low as $1000 a month.
