Not A Fan
My dog is not a fan of this supplement. I’m hoping he will learn to like it. I wish I could hold his nose for him while he eats. I’ll keep trying. Maybe smaller

Energy Level Increase

Willow is going to be 14 on 12/17/25 and was recently diagnosed with renal failure and incontinence. I started dosing her Rx Vitamins Amino B-Plex about 3 weeks ago and now I'm thinking the vet misdiagnosed her because her appetite has increased and the urinary leaking has stopped.

I read somewhere b vitamins could help with Horner’s syndrome. When my senior golden got this in one eye, I tried this b complex supplement and it helped to heal it. I can’t remember but I thought the big bottle and by the time I finished it it was cleared up, I think about 2 months. Put on her food in the morning and evening.
