My dog has enlarged lymph nodes & breathing. Is it lymphoma or viral?

Updated On September 23rd, 2025

Pet's info: Dog | Goldendoodle | Male | neutered | 85 lbs

My dog in the past week has been very sick, not eating, enlarged lymph nodes, he had a uti, he had to be force fed. Medicines didn’t help. The vet took a biopsy for the possibility of lymphoma and gave a new set of medications. The uti passed and he pees regularly. I still didn’t get the results for the biopsy but his lymph nodes decreased 40% in 2 days and he eats by himself. His breathing however is accelerated and not normal. Do you think my dog has lymphoma or could it be viral. Treatments?

I'm sorry to hear that Rocky is having this problem. Until the biopsy results come back, it's impossible to say if this is lymphoma vs some type of infection - it could be either one. Treatment will depend on the diagnosis. So for now, I would continue on whatever medications he's currently taking as prescribed by your vet, and wait for his test results to come back. Your veterinarian will be able to advise you on treatment recommendations at that point, depending on what is found. For now, if he's having any difficulty breathing, the safest bet would be to take him to your nearest ER to be evaluated to make sure he doesn't need oxygen or other emergency care today.
