Hello, My name isXXXXX will try and help you as best as I can. First a few questions: what kind of liver infection did your dog have? is he able to walk at all right now? Do you see a head tilt at all? Any vomiting or diarrhea? Is he on any medications at the moment?
The liver infection was bacteria in nature. He can walk. He dies gave a head tilt. Little to no no appetite. Vomited once think he overate befire this occured. No diarrhea.
I think he likely has vestibular disease, most likely due to idiopathic vestibular syndrome also called old dog vestibular syndrome. This is a condition that many dogs will recover from over a period of a few weeks. Treatment is mainly going to be symptomatic with medications to control nausea and vomiting. Signs however may not improve and if that is the case, a brain tumor will need to be considered and would require an MRI to fully diagnose. If you begin to see any seizures, a brain tumor is much more likely.
Would he survive a tumor removal? What are his chaces statistically?
I think the tumor is much less likely, however it should still be on the list. If it was a tumor, it would most likely not be removable. That being said, this is most likely just old dog vestibular disease and I would only consider a tumor if your dog did not improve over the next month or began having other issues, (mostly thinking seizures).
You're welcome. Please let me know if you have any more questions. I'll check up with you in a few days to see how your dog is doing. Have a good night, and please don't forget to leave feedback. Thanks.
