Michelle, try not to worry or think the worse (I know, easier said than done!). My Bichon had almost the exact same thing happen, he developed a lump seemingly overnight on the very lower back/upper haunch and it was bigger than a golf ball when it appeared and got bigger by the next day when i took him in. They aspirated and mentioned the same scenerios your vet did, then had surgery the next day and it turned out to be just a fatty lipoma. It was such a relief and hoping it is the same diagnosis for Jada! I know and understand how worried you are! but try to believe it will be a non issue after they remove it. Keep ♥ all your thoughts positive for Jada. Sending healing prayers for Jada and huggles for you!!
