My 10yo lab mix, Raven, has been healthy all her life. All of a sudden she got really sick this summer with dramatically elevated liver enzymes, vomiting, etc. We treated her with homecooked foods for 4 months and a round of antibiotics. All her tests (for leptospirosis, Lyme disease, etc) came back normal, so we never figured out what caused her illness. Her liver enzymes are normal now. But she has slightly low platelets.
Then twice in the past couple months she's had hot spots. She never had those before. Right before Thanksgiving, she chewed a hand-sized raw spot on her flank by her tail. It got infected, full of pus, and was very painful. She developed a fever and the shivers. She got goopy eyes and painful hips. A few times she wobbled and stumbled when she walked. She's itchy all over. Again all the tests were done and everything was negative (except the low platelets I mentioned above.)
It's now a week later. Antibiotics and skin ointment healed the hot spot, and her fever is gone now. Still isn't back to normal though. Still really itchy all over. Poor thing has been wearing an e-collar all week.
I have no idea what's going on with her! (Let me know if you have any ideas!)
There's a pet medical intuitive who owns an herb store in a nearby town. She does iridology too. Have you ever been to one? Would you go to one?
