Save Bella: Our Beloved Family Dog

My dog Bella we have had for 5 years randomly started having a seizure which is normal for chihuahuas but after she couldn’t walk we don’t know what is wrong with her yet 100 percent but the vet is saying since it’s not a disease it’s most likely a brain tumor because they did a blood test and numerous tests on her my mom has been crying all day this Dog is more than an animal to her and to all of us she is a part of the family and I don’t want to lose her the tests alone and everything else to try and help her are around $1000 percent appointment and we don’t have the money for that if you can help us it is very much appreciated
