Bella's Tumor Removal

Hello!  We are Marissa and Gabrielle- our little pomeranian has developed a tumor that's pressing on her bladder and it's noticable from just looking at her or petting her.  It's grown into a big lump and it's gotten considerably bigger even in just the past month.  This is the second time she's had this tumor develop... unfortunately we don't have the funds this time to pay for it right now and we're worried due to how rapidly it's growing.  The saddest part is that it's obviously causing her pain...  she's having constant UTI's and lately she's just been crying all the time and we think she's in a lot of pain.  We've tried home remedies for UTI's on dogs, but based on the tumor she had a few years back, it seems like nothing will help her except removing this tumor.  It's breaking our heart to see our babygirl in pain....  we've tried everything and we've been trying to save on our own, but we just don't have the funds to pay for her right now..... and it's killing us that we' can't.  Bella is such an amazing, fun, loving dog and she holds such a huge spot in our hearts, that's why it breaks ours that we can't help fix her right away
