Our dog has several masses inside and on the outside left hind leg. We have has him to two vets and one says remove them and the other said it cant be removed because of where the masses are located. Both suggest a aspiration/biopsy.
The second vet we went to said that it couldn't be removed only amputation.
Before making the decision about the amputation or if it can not be removed, it is necessary to do the aspiration/biopsy.When the vet gets the results of the biopsy,then the vet will be able to say:the masses can be removed or not or needs a treatment or amputation.
