Anyone's boxer baby experienced the same and what was the outcome

[Julie T]

We got a beautiful white deaf boxer female 8 years ago. I was wondering if you could give us some advice. Last Thursday she slept all day. When she did go out into the garden she was very unsteady on her feet and seemed disorientated. Friday she was still the same but toppled over. We immediately took her to the vets who done bloodwork and checked heart lungs etc but all was fine with the results. Gave her injections of pain killers antibiotics and anti inflammatory. That evening she seemed to look like she was going to sit but not like her back legs were weak. we had followup appointment next morning. The vet said it's neurological either lesion on her brain a tumor or a stroke prescribed antibiotics and steroids. She is completely back to her old self. The vet basically said she will be on steroids for the rest of her life. She has had a lot of ear infections but apart from that she has been perfectly healthy. Have you had any experience with anything like this? please advise
