Okay. I have news!
The last two weeks...
Ruger has had swelled lymph nodes across his entire body. The swelling was increasing at an exponential rate, and so my heart started sinking...that it had to be cancer, and then he started to stop eating which is not like him and his drinking went through the roof. He was emptying 2 water bowls every hour. Mastiffs are genetically prone to getting lymphoma and all of his symptoms mimicked what I had read through several research articles and medical pages.
No vets wanted to see him since he doesn’t like people. We finally managed to get him scheduled with one but this was 2 weeks after the initial swelling and he was having trouble breathing. I was preparing myself for the worst (and by preparing I mean I was sobbing every night and forcing myself to talk about it in public so that way I could not be so sad).
His vet appointment was yesterday. Ruger was so perfect. He had one accident (peed on the floor) when a couple barged into the vet clinic even though they could clearly see Ruger was right by the door. During the exam, which was done in the back room on the weight scale, we pulled blood (a hind leg since they didn’t want to be near his head lol) and he didn’t even cry out even after they blew a vein.
Tests...
At the vet office, we had the 4DX test done. Ruger came back heartworm positive which was something I hadn’t even considered, and my heart stalled.. I was in the set mindset that he now had heartworm AND lymphoma. He was put on 14 pills a day. (5 antibiotic and 2 steroids twice a day)
Bloodwork was sent to an outside lab and we just got the results back 20 minutes ago. Kidney and liver levels were tested as well as a CBC for the WBC.
Results are...
Kidney and liver levels were perfect!
The vet told us that 30k WBC was high infection, and anything from 60k and above was likely cancer...
His WBC was 23k!!!
The vet said that she isn’t worried that it’s cancer, and to update them in 4 days if the swollen lymph nodes aren’t going down.
TLDR: Ruger our mastiff was thought to have lymphoma due to symptoms, he has heartworm instead and vet isn’t concerned about it being cancer.
