I am sorry to read this, I will be praying for the Big Mack. Kendra, IF he has to have chemo Please contact a homeopathic vet for supplements & diet to help him through chemo. My Sparky has lymphoma & in remission now for 3 1/2 yrs, he made it through chemo with little problems & actually only had 1 problem & that was caused by a mistake his oncologist made with his metronidazole dose @ 35 mg & should have been 250 mg
IDK what he was thinking with that but once I figured out he was on the wrong dose & got the rite dose in him, he was fine. Sparky is a rescue who was near death when we found him & he's never been quite rite health wise, maybe like Mack, but I believe the supplements & diet were the key to his successful chemo & remission. We did phone appts & I can give you his number if you like, just PM me.
