Current cure rates using stem cell therapy in dogs approximates that achieved in humans, 40-50%. When cost is a factor, prednisone used alone can improve the symptoms dramatically, but it does not significantly affect the survival rate. The average survival times of dogs treated with prednisone and untreated dogs are both one to two months. [1]
Additionally, dogs have much larger olfactory mucosa and a larger part of the brain dedicated to odors. Whereas in humans, 5% of the brain is dedicated to odors, in dogs this figure is 33%. Dogs are able to detect odors 9 orders of magnitude more faint than humans, who can detect odors up to 1 ppb .
Dogs have an overall reported incidence of mammary tumors of 3.4 percent. Dogs spayed before their first heat have 0.5 percent of this risk, and dogs spayed after just one heat cycle have 8 percent of this risk. [1] The tumors are often multiple. The average age of dogs with mammary tumors is ten to eleven years old. [6]
In about one fifth of the dogs with a mastocytoma, feeding instability, vomiting, tarry stools and anemia occur as a result of gastric or duodenal ulcers, [10] in autopsies such ulcers are even detected in more than 80% of patients. [18] About 80% of the dogs with such ulcers are euthanized due to poor general condition. [19]
