Thanks for getting back to me, even though it's been a few days:)
It's great that she's doing so well; I'm constantly amazed at these older dogs after a splenectomy!
Dogs don't become anemic when their spleens are removed. In fact, red blood cells can be sequestered in this organ, thus causing anemia. It's possible for some dogs to do better after their spleens are removed but much depends on the underlying problem that affects this organ.
Without a biopsy of the spleen, it's obviously going to be difficult to know how serious the situation might be with Noodle but the possibilities are either cancer or a benign process such as multiple hematomas...although I suspect that this is something that you already know.
1. If this was cancer, then clearly the long term prognosis isn't very good...not because the spleen was removed but primarily because there is usually metastasis to other organs by the time the diagnosis is made. The average life expectancy could be anywhere from 4-6 months.
Something to consider for Noodle would be a cancer diet which is high in protein and low in carbohydrates. There is a prescription cancer diet (N/D) which could be given but you would have to purchase this diet from your vet...it's not available in stores. There haven't been any specific studies, though, that prove if it will help with this kind of cancer.
There are cancer diets listed on the internet but you have to be somewhat careful of them since they may not be balanced.
High doses of fish oil (fatty acids) are often recommended for their anti-oxidant properties but, again, no specific studies have been done to prove their effectiveness in slowing the progression of cancer.
Probiotics such as Forti Flora may be helpful; these products can help boost the immune system.
There are a number of spices shown to have anti-cancer activity.
Garlic --Try FRESH minced garlic - about 1 clove per 40 pounds of body weight. Be careful of the dose, though, since in large amounts, garlic can cause toxicity (anemia). A cbc (complete blood count) should be monitored regularly to monitor potential problems.
