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

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 doses initially will be better.

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

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. Seems coincidental with the use of the above mentioned product. In other words, I highly recommend this product for senior Dogs that are starting to show wasting away issues.

Fixed Horner’s Syndrome

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

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.
