My name is ***** ***** I’ve been involved professionally with dogs in the health and behavioral fields for over 18 years. It will be my pleasure to work with you today.
I am assuming your dog had the version of vestibular disease related to old age. That does resolve itself over a few weeks as a dog learns to cope with it.
I personally have the human version of vestibular syndrome which is vertigo. The way my doctor explained it is that certain forms of the disease are due to things like ear infections or tumors disrupting the vestibular system. Others are viral (in the case of vertigo). With this form the patient learns to live with the disruption and how to move without serious dizziness and nausea. For bouts of vertigo, your vet may prescribe dramamine or bonine to help with the symptoms. You can read about dramamine and bonine usage, precautions and dosage here:
Now many dogs the cause is from a different cause such as ear infections or a growth in the area of the vestibular system. In those cases, antibiotics or other treatment is necessary to relieve the symptoms.
Many dogs experience car sickness even without having vestibular disease. It just affects your dog worse than normal. I'd ask your vet about possibly using dramamine or bonine for car rides to relieve the symptoms. Perhaps if you start treatment right before the car ride, it will stop the symptoms from continuing for days.
