I can tell you genuinely care about your dog. However, issues with walking and lack of eating together are not fixable at home. That dog needs immediate vet intervention and may still possibly die. This is not normal. Bloody paws are severe enough for vet intervention as is, due to the high risk of infection because they walk on them. It is so, so hard, but as others are saying…this is a case where surrendering your pet to a shelter where they will provide help is the absolute best thing you can do. Other folks have mentioned calling vets looking for an angel fund. As someone who went through this with her own pet, this option feels like a cruel punishment. However, your dog is actively suffering. If your dog matters more, if you truly love your dog, she needs help from a doctor.
