Help save my dog by donating money to vet bills

This go fund me is for my french bull dog, Angus. This is our last option or we have to put him to sleep My family got him when I was around ten years old and he’s grown to be my best friend over the years. Last night, he started throwing up blood with no visible reason on why. My mom and stepdad had to go to an emergency vet visit. I, however, had to stay home with my baby sister. They weren’t allowed to go in with him due to COVID restrictions, but they had to wait around. They wanted him to stay overnight and put him on oxygen and fluids. That specifically costed us around $2,000-$3,000 without even knowing what was wrong with him. This is such an issue because my stepdad is the only one working and we still have to pay rent with the holidays coming around. We learned today that he has pneumonia, but they’re still unclear on why he was vomiting blood and might have a blockage. With pneumonia that will cost us for antibiotics and he has to stay for another 3 or 4 nights. If he does have a blockage that can cost up to $9,000. I’m starting this asking for help. Every dollar counts
