My dog with hemangiosarcoma is weak, pale, not eating. What's wrong?

Absolutely, you are correct in thinking that there could be an internal bleed causing these episodes of pale discoloration to the gums. An abdominal ultrasound and chest x-rays would be helpful right now to see what is going on internally. There could be a catastrophic event at home if a major blood vessel bursts or a large vessel bursts / ruptures on a tumor in the abdomen causing severe hemorrhage in the abdomen. If you notice the belly getting larger, there may be a slow bleed inside the abdomen. I would have Kayah rechecked as soon as possible so that you can get more information. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Thanks for using Petco Pet Education Center, formerly Petcoach! Loss of appetite can be observed with many conditions such as gastroenteritis, dietary indiscretion, kidney disease, pancreatitis, among many other possibilities. This could absolutely be due to anemia given her pale mucous membranes. I recommend that you have Snow evaluated by your veterinarian for further assessment and treatment. They would be able to check for these possibilities and others depending on the findings on exam. Treatment would be based on findings. Good luck and have a good night! Hoping for a speedy recovery!

Hi. The pale gums and weight loss are very serious signs! I don't know the age, or sex, or history, so it's a bit hard to review the most likely possibilities. But with pale gums and weight loss, 8d be concerned about internal bleeding, cancer, immune mediated disease, parasites, k8dney disease, and many more. An exam, lab work, and x-rays will be needed to get down to the the potential cause. I would recommend getting him seen right away.

If she has pale gums then she needs to be examined by a vet immediately to determine the cause and treat, especially if she also has abnormal breathing. Please call your vet or go to an emergency clinic. She could have an infection, parasite, clotting/bleeding problem, hemolytic anemia, mass, etc. and may need immediate treatment.

I'm so sorry to hear Samson is so sick! I'd recommend taking him to see a veterinarian right away so they can help you decide if he is suffering. All of the signs you've described make me concerned for blood loss, organ failure, or cancer so I think it's very important Samson see a veterinarian. Thank you for using Petco Pet Education Center, formerly Petcoach.

With a Doberman, I would first want to rule-out heart disease. Dobermans are predisposed to having a heart condition that can cause heart failure, which would present like this. However, the fact that she is a cross makes hereditary heart disease less likely. There are many other conditions that can cause these exact same problems such as intracellular parasites/bacteria, intestinal parasites and blood clotting disorders leading to anemia. Either way, the fact that she is pale and lethargic warrants an urgent visit to the veterinarian. The vet will be able to help narrow-down the cause of this and advise the best treatment. In many cases, these signs can be completely reversible and she can have a good quality of life again. I hope that helps and Sassy gets better soon.

The white or pale gums are a sign of severe anemia. It could be due to a high worm burden or it may have another underlying cause. Vegeta should be seen by your veterinarian to diagnose the underlying cause. Given current circumstances, you may need to drop him off at the clinic then wait for your veterinarian to call you. Supportive care may be indicated until he is feeling better.
