Urgent Vet Visit Needed for Bella's Pain Relief

Lately, we’ve been struggling with money, and for about a year and a half, we’ve been trying to gather money to take my dog, Bella, to the vet. She’s in a lot of pain and lately can barely even control her bladder. She never used to whimper and whine, but now she does. Sometimes she can barely even walk. We need this money to bring her to the vet. I love my dog, and I want her to have the care she deserves. Please help us. We aren’t even sure what’s wrong because we don’t have the money to take her for a checkup. She’s a loving dog who’s kind to everyone despite her hurting. Please help. This money will only be used to help her with medical bills
