My 8 year old cocker spaniel has been diagnosed with osteosarcoma,

Customer Question

My 8 year old cocker spaniel has been diagnosed with osteosarcoma, she had her hind leg amputated 14th Dec 15 so we are at the 5 month post op period.
In the last few days she's been extremely lethargic and only eating her evening meal, not bothering with breakfast at all.
With 3 legs she remained extremely active and it's only last couple of days I've seen a dramatic change in her. She also seems to be not walking correctly, it's difficult to say whether she's lame having only 3 legs but it doesn't look right when she walks.
I took her to our vets on Monday where she had chest X-ray and her rear limb checked, X-rays showed no sign of cancer spread of a tumor in her lungs. I did feel as if I'm over reacting after finding no problems at vets but I know she isn't right. I realise cancer hasn't spread to lungs yet but could there be another way this cancer is affecting her?

Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today. What medications is she on just now?Any breathing changes? Does she seem winded more easily?Any gagging, retching, lip licking, vomiting, or diarrhea?

She's on no medication as she's been fine and as X-ray of chest clear no medication was offered. No breathing changes or any of the above

Thank you, ***** ***** am glad to hear that she has no breathing changes, since we can have microscopic cancerous lesions in the lungs that aren't yet visible on xray. (It is these that tend to grow in time and thus become visible). And in regards ***** ***** question, we can see this tumor spread anywhere in the body which can then cause bother. Its just the reason we focus on the lungs is because they contain our smallest blood vessels (where cancer cells are most likely to get caught) and thus the most common place for spread. In any case, even if she had a clean bill of health at yesterday's examination, your feelings that she isn't quite right isn't over-reacting. These signs are subtle and don't point to one issue, but we do need to take note of this for Phoebe. It is possible that the warm weather is causing her to feel off (many dogs eat less with this) or even a brewing gut infection is making her less keen to eat. As well, we cannot rule out that she may be a bit sore (perhaps she has had a muscle strain recently, underlying arthritis, or phan***** *****mb discomfort), even if she is putting on a brave face at the vets.With all this in mind and since she cannot tell us what is causing her to feel less then 100%, I do think some supportive care is indicated. First, I would suggest that you ring her vet and discuss a trial on dog safe pain relief just in case (if she improves, then discomfort was likely here). Or we could even consider OTC joint supportive treatments like omega 3 fish oil, glucosamine, and chondroitin.As well, to counter any low grade stomach upset, consider offering a light diet option for a few days. Examples of an easily digestible diet include cooked white rice with boiled chicken, boiled white fish, scrambled egg, or meat baby food (as long as its free from garlic or onion powder). Further to this, if we see any hints of nausea, then we can also treat with an OTC antacid like Pepcid (More Info/Dose @ or Zantac (More Info/Dose @ These are usually given 20 minutes before offering food to allow absorption. Overall, while her signs are subtle and she didn't give her vet any overly clear signs of problems, I do think what you are picking up is significant. So, I would suggest trying a light diet and discussing covering that discomfort base just in case. Hopefully, as the weather cools next week, we will see her get back to normal but it is worth ruling those subtle issues out (especially if she isn't walking quite as normal) since she is telling us there is a mild issue making her feel not quite right.Please take care,Dr. B. -----------------------------------------------------------------------------------------------------------------If you have any other questions, please ask me – I’ll be happy to respond. **Afterwards, I would be grateful if you would rate my service by clicking on the "Rate my Expert' button at the top of the page as this is the only way I am credited for helping you.
