My 5 year old male labrador has been experiencing recurring episodes of weakness or paralysis in his hind legs. His front legs work normally, but during these episodes he cannot stand or walk properly. He gets frightened and starts shaking. The episodes usually subside after I gently massage his hind legs. This happens around 3–4 times a month. Our local vet prescribed Gardenal 30 (½ tablet twice daily), suspecting a possible neurological or nerve-related issue. I'm looking for recommendations for a really good veterinary neurologist or experienced specialist who can properly diagnose and treat him. I'm willing to travel to Kolkata if necessary. Also, based on these symptoms, does anyone have an idea what condition this could be? Could it be a spinal, neurological or seizure-related problem? I genuinely want to find the underlying cause and get him proper treatment. Any recommendations would be greatly appreciated.
