I've been searching the internet for all the causes and illness, but I'm stuck. So this is the situation. We are living in a small town, and 10 days before, my Labrador retriever was bitten by a tick. I thought nothing serious and removed that tick myself. Four days passed, I was walking in a park with my lab(it was a sunny hot day) and when we get back home I noticed that he started panting fast and heavily even when lying on the ground.
I thought something is wrong and took him straight to our local vet. Told him about that tick and he injected something against Babesiosis. Also some antibiotics. My dog's body temperature was 102. Now he has been on antibiotics course for 5 days and his condition is getting even worse.
He is very tired all the time, wants to lie, sleeps all day, breathing fast and drinks lots of water. Urinates for like a minute, but not that frequently. Eating is normal and he wants to eat, also no diarrhea. Today that vet tested a urine sample and said that everything looks normal. He doesn't know what could be that inflammation cause... I don't know what to do, how to help my boy and it's breaking my heart
