Family looking for puppy in Vancouver, Washington For Sale

Hi our family would love to add another pup to our home we are not really set on a breed we just want to naturally fall in love. Only thing is my husband says if we want one we need to find one for free so we can afford the 300 downpayment for banfield wellness insurance. Im hoping that someone will give our family a chance . We are a very loving family . We have 3 children 2,5 and 7 also a maltipoo that is almost 2 she is the happiest puppy ever.
