Go to Better business Association and read the full history on what transpired with Bret MArk. He totally lied. He was offered a replacement puppy immediately and he turned it down , we offered to pay half of any surgery and none was required by the vet. See documents from the actual vet from Mark's cardiologist saying no treatment or any further visits was not required. He absolutely lied and is why he dod not respond to the BBB inquiry after I supplied all documents.
