Ask a Dog Vet and Get Answers to Your Dog Veterinary Questions
I am sorry to hear you are worried about your dog. My name is Rebecca. I am a veterinarian and will do my best to help.
It is unlikely that a dog would bleed to death from an abscess. If you look at his gums, are they pink or pale in appearance? If his gums are pink, he is not losing too much blood. Direct pressure may help slow the bleeding, and some might a cool compress like a bag of frozen peas.
The elbow is a common site for a "hygroma", swelling and fluid and blood and sometimes infection, especially in larger or overweight dogs. These are usually treated with antibiotics, bandaging, and pain medication. If this is a hygroma, I like a bandage called "Dog Leggs" for covering and protection. You can find these online.
He probably needs to see a veterinarian for treatment and antibiotics.
Let me know what else I can answer or help with.
I hope you were able to see what I sent. How is he doing? Let me know if this was helpful.
