Why is my elderly Jack Russell vomiting dark, jelly-like blood?

I would be concerned that Shadow was throwing up blood yesterday, but given that you are seeing any more of that red jelly substance, it could be something that she ate. Her vomiting could also be caused by a GI illness, intestinal parasites, or a foreign body. Because she is eating and drinking normally, and otherwise behaving normally, I can give you a home remedy to try to see if that helps. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the vomiting continues in the absence of food, she vomits the bland diet, vomits the red jelly substance again, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away.

Aw poor Jacky Gill! I'm very concerned about the blood in the vomit as this can indicate serve Gastrointestinal inflammation or ulcer formation. Jacky should see a veterinarian right away as he likely needs prescription medication to stop the vomiting and diarrhea. He may need fluids to help rehydrate him. It may also be a good idea to have X-rays done to ensure there is no intestinal blockage. Once he has received medical care a bland diet of boiled chicken and sweet potato or rice may also help him recover. Thanks for using Petco Pet Education Center, formerly Petcoach and I hope Jacky is feeling better soon!

Lucy could have a mild case of inflammatory bowel disease, a food intolerance, or an intermittent infection. The blood is somewhat concerning. I recommend discussing with your veterinarian if they would like to do any tests on Lucy or any medication. Your veterinarian may do this via a phone consultation or may require an exam first.

No, this isn't normal and can be a sign of problem such as irritation of the GI tract, anal sac infection, or a foreign body. I'd take Charlie Boy into a vet today to get this checked out since it's been going on for a week now.

These signs could be compatible with an inflammation infection of the gastrointestinal system and surrounding organs (like pancreas and liver). Dark feces could be compatible with a gastrointestinal bleeding in the upper part of the intestine. A clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like abdominal imaging as ultrasound or radiographs) may be needed. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

There could be several causes for the symptoms you have described, including chronic pancreatitis, IBD, intestinal parasites, food allergies or intolerance, GI lymphoma, bleeding disorders, some cancers, among many other things. I would recommend that you have Bonnie checked out by a vet. After a thorough physical exam, they may recommend diagnostics such as bloodwork, intestinal parasite screening, x-rays, or ultrasound.

That is extremely concerning. Coffee ground colored vomit or stool could indicate a bleed in the GI tract or stomach. If Lucy has been vomiting like this for several days, it is best to seek out care from your vet or an emergency clinic right away.
