Sparky is still with us & it's been 13 mo since his diagnosis. He is still doing well & his same crazy little self. We were told 6 mo to 2 yrs is average life expectancy for lymphoma with the majority between 12 to 14 mo. We also contacted a holistic vet & had him on supplements & diet during his treatments to help with side affects of the chemo & I believe is why he did so well. A couple of things to keep in mind, #1 have plenty of Metranidazole on hand & #2 Cerenia. The only problem Sparky had was one of the drugs can cause colitis & the Oncologyst only gave a Hamster size dose of Metranidazole
So it was not enough to keep him comfy, once I figured that out & called my reg vet & we upped the dose, he was like new in just a couple of hrs. Every pup responds a little diff so if there is a problem with vomiting or yucky poos, Call the vet ASAP to see if you can adjust the dosses for him.
