A. Some tumors can grow relatively fast but typically not that fast. With dogs that are pretty hairy it can be difficult to see tumors growing. They can remain inconspicuous for a while when they are smaller, then a sudden growth in size finally reveals themselves to us. By that time they could have already spread to other vital organs to caused malfunction. I am so sorry for your loss. Losing a pet can be heart-breaking and only time can begin to heal the void of a lost pet.
A. Some cancers grow very slowly over the years and others grow very fast. This depends on how fast the abnormal cells divide and so make new tissue. It is quite possible that most of her tumors were invisible inside the body, and when they had reached a certain amount , the cell division just was so intense that the abnormal cells quickly seeded into the skin and muscles via the blood stream and lymph fluid. Often a body can keep cancer pretty much in check via the immune system and then you would not notice anything, but at some stage the body gets exhausted, and the cancer takes over. I am very sorry for your loss and I am happy that you were able to give her the gift of ending her suffering.
