Good Afternoon and welcome! I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
If there are multiple places where the Lymph nodes are enlarged such as the Mandibular nodes by Tiny's jaw and the Popliteal nodes by her rear legs, then this is most likely Lymphoma. If this were due to an infection , only one or 2 nodes would be affected in a certain area.
The treatment is appropriate because not only is your vet using a good antibiotic but also using Prednisone, which is a good chemotherapeutic medication used for Lymphoma.
I would have liked to see your vet do a fine needle aspirate of one or 2 of these nodes since , if this is :Lymphoma, the quicker it is treated, the more time Tiny would have with you possibly.
Does that make sense to you?
Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please REPLY so I can clarify for you.
Sincerely, XXXXX XXXXX
