Mammary tumours in G S D - Page 1

A month ago, my 12 year old female German Shepherd had 2 mammary tumours removed. One was a benign tumour that had been there for at least 5 years and the other was cancerous (located between hind legs). The pathologist wasn't sure if the cancerous one was a transitional tumour or a primitive tumour. He suspected that if it was transitional then its a secondary tumour possibly from the bladder although she doesn't have any symptoms of urinary cancer. If it's a primitive tumour then he thinks it's the primary tumour.

A few days after surgery one of her hind legs swelled. 1 week after surgery, an infection developed at the drain site. She had a second surgery to "clean up" the areas that included removing a lot of hemotomas (clotted blood). The swelling in the hind leg went away and stayed that way even after I stopped giving her meloxicam.

On Thursday (a month after the 1st surgery) both her hind legs swelled. One worse than the other. The next day, I took her back to the vet also because I noticed a new lump and she seemed painful when I took her for a walk and when she tried to lay down. The vet wonders if the new tumour is inflammatory mammary cancer and has prescribed a drug that women take for inflammatory breast cancer in addition to a diuretic. This new tumour is a fair size and has developed over 2 weeks.

I'm wondering if anyone else has had a dog with one type of cancer and then after removal, a new type of tumour developed over a few weeks.

I have her on turkey tail (coriolis) and theracumin, wild salmon oil, and just started giving her 500 mg of vitamin C.

She has EPI and has been on a raw or home cooked diet her whole life, and gets regular exercise. She only gets a rabies vaccine.

Any suggestions would be appreciated.

Thanks,
