My little boy boxer of 6.5 years old just got diagnosed with hemangiosarcoma (cancer) of which was found in his hind leg...in the thigh. His back leg is really swollen and he is not using it currently due to it being in his muscle. All of this just happened in the past 1.5 weeks....needless to say we are sooo sad. The vet has prescribed tramadol and gabapentin for pain (still isn't using his leg). We have an ultrasound and xrays scheduled in 2 days to understand if it is in other places. Does anyone have any experience with this awful disease? Any suggestions?? Also prayers are certainly appreciated.
