Our 9 year old dog Mack was diagnosed with lymphoma after we noticed his lymph nodes swelling a few months ago. They tried two rounds of strong antibiotics first, thinking it was an infection, but the lymph nodes remained and got larger. Two weeks ago they took tests to confirm what they had thought, it was lymphoma. They put him on a strong dose of prednisone twice a day. We thought we would have a few months left with him, however the side effects from the prednisone made him miserable. Restless and unable to sleep at night. Heavy panting. Very thirsty and frequent urination. We made the decision to wean him off the steroids 5 days ago so he wouldn’t be plagued with these symptoms the last part of his life. Yesterday, his breathing/panting picked up and seemed to distress him so we called the vet and made the decision to put him down. We got to hold him and comfort him as it happened so he went peacefully. But the grief is so strong. This was my first pet that I’ve had this long. I keep second guessing myself if we did it too soon. There were still times when he would be good and playful..then I tell myself he couldn’t have been feeling good. I feel like we did the right thing but the second guessing myself if hard. Anyone else have a similar story with lymphoma?
