A woman writes to holistic vet Dr Middle about her Pomeranian dog which has a tumour that she, as a pensioner, cannot afford to have treated with chemotherapy. That was two years ago, and now the lump is "40 or 50 cm in size".
If Wikipedia is to be believed, Pomeranians average 13-28cm high. If Nova is to be believed, the tumour has now grown to twice the size of the dog. Even if the dimensions are taken as 40-50mm it's still a large tumour, and the implication is that in the two years it has been growing its owner has not been back to the vet.
Dr Middle advises (EoR's emphasis):
It does sound as if the lump on Snowy's leg is a nasty one if the vet has recommended chemo. If it is a tumour of the bone, or an osteosarcoma, then it may have spread to other parts of the body, but small dogs rarely get this type of tumour. It is more likely to be a fibrosarcoma, which is unlikely to have spread. So if the vet has done a biopsy and knows it is this type of tumour, then this might sound drastic, but amputating the hind leg may be the best and most cost effective option if the lump is causing him pain. This would be easier and more successful than trying to remove the tumour, according to the information you have given me. Small breed dogs do not carry much weight on a hind leg and usually do well after an amputation.
However, if the lump is not causing him pain, that is, if he is using the leg without much of a limp, then it may be best to do nothing about it, or use herbs to reduce its growth rate. You can buy these herbs cheaply from a herbalist or health food shop which sells herbs, in either a dry herb or liquid tincture form. The herbs are, Burdock, Slippery Elm Bark, Sheep Sorrel, Red Clover, Indian or Turkish Rhubarb Root and Blessed Thistle.
Call EoR old fashioned and alarmist, but his recommendation would be for a vet to examine the dog urgently to determine the nature of the growth and how it has progressed. A fibrosarcoma is less likely to have spread, but is also extremely rare in comparison to osteosarcoma in dogs. How Dr Middle can differentiate based on a brief letter is an amazing demonstration of her skills.
Sadly, at 11 years old, and this advanced, it may well be that nothing can be done. Sitting back and seeing whether a hodge podge of herbs and doing nothing will effect a cure, however, are the sort of actions that kill people suffering from cancer.
Dr Middle also warns most strongly:
do NOT feed him dried commercial food, as the carbohydrate will weaken his immune system
because, you know, processed carbohydrates are all different from any other carbohydrates, with a completely different chemical structure, and they go straight for the immune system.
