Good Morning Karen and welcome to Just answer. I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
I am so sorry to hear about Munchkin's condition. I know this is very scary not knowing what is causing this.
These are typical signs of a neurologic defect. This defect could be due to an infectious cause affecting the Vestibular Apparatus causing this imbalance. This could also be due to head trauma that you may not be aware of or a vitamin B deficiency.
Also, an inner ear infection can cause this neurologic issue.
Because there are a few possibilities and Munchkin is otherwise healthy, it is best to treat for all of these.
1. Give aspirin at 3 mg per pound every 12 hrs to decrease inflammation that may be compressing the nerve supply.
2. Give Munchkin daily injections of a vitamin B complex that is available at the farm supply. The dose is listed on the bottle.
3. Give Munchkin Penicillin G daily for 7 days that can also be purchased at the farm supply.
4. Worm Munchkin with Ivermectin in case there are parasites.
5. Check Munchkins ears to see if there is any evidence of infection...if so, clean with peroxide.
If Munchkin does not respond to this treatment, Karen, have your vet examine him...he may require steroid treatments to get him past this.
Does that make sense to you, Karen?
