We just started this supplement so obviously there is no improvement yet. He loves them so that's a big start!

My veterinarian suggested this for one of my cats.

Nougat is a big eater and not picky at all. He wouldn’t go near this stuff no matter how I disguised it.

My dog didn't respond. She still has a rash. Her allergy must be from a different source that this item doesn't address.

Great taste but didn't seem to help allergy

Honestly our dog must have allergies that can't be treated by a supplement of any type. We've tried several but the only solution is an allergy medication Apoqu

I think it is helping - too soon to know for sure

Skylar of course loves these little yummy duck tidbits- I have seen a slight improvement in less itching but it may be too soon to know for sure

Disappointed

I have a Beagle that will literally eat everything & everything you put in front of her. She would eat them for the first 2 weeks and then kept spitting them out

Did not work at all

It seems like it made the itching worse. Generally I like VetriSCIENCE products but NOT the Allergy plus.

It does help!

My pup suffers from severe allergies (food + atopic dermatitis)-- her paw pads were cracked and brittle from her chewing her feet. I once caught her putting her

My pup suffers from severe allergies (food + atopic dermatitis)-- her paw pads were cracked and brittle from her chewing her feet. I once caught her putting her entire foot in her mouth (bless her!) She would experience immediate relief, but not long lasting. I found that vitamin E works synergistically with the Allergy Plus supplements. Her paw pads are immensely improved. I would recommend this product!
