Similar to previous commenter, I also have a 13.5 year old shiba inu who very suddenly got horrible balance, falling, confusion, then vomiting. Rushed her to the vet thinking it could be a stroke. All blood and urine tests came back normal. The vet sent us home with Meclizine 25mg tabs to be cut in half, one half given every 24 hours. Praying hard this will be a cure. She said the alternative at this point is it could be a brain tumor. Hoping it should clear up within a week but if not I was given a referral to a neurologist veterinarian. She had ear infections when she was young but nothing recent. Worried sick, it’s such a scary thing to witness especially having had other animals die of strokes. I originally put her in a dog pen but she kept falling into the metal sides so I put her in a fabric cat pen with a pile of blankets and she’s been sleeping ever since. Small interest in water but hard for her to drink, no interest in food. I really hope she’ll be okay, poor Serendipity 🙁
