Can I feed Anihist in the am and Histall in the evening? Is this a good idea?

Answer by Chewy • Nov 17, 2021
The AniMed Natural AniHist H Respiratory and the AniMed Natural HistALL H Allergy Relief Powder are similar in ingredients and should not be mixed together. To use both, you would have to stop one and wait 24 hours before giving the other.  

What’s the dosage per kg?

Answer by Chewy • Dec 08, 2022

So far it’s clearing up the allergies

First off the smell is HORRIBLE. If you have a picky eater they won’t eat this stuff. Luckily I have a hippo and he eats anything. My QH has been on this for less than a week and by day 2 I could already notice a huge difference. He had allergies when we purchased him but when he came to our house they became so much worse. Zyrtec wasn’t helping at all so we gave this a try. He was always scratching his face and legs until they bled he was soooo itchy. I haven’t seen him scratch his face in days since starting this! I hardly ever write reviews and was on the fence about purchasing because of the mixed reviews but it was worth it for us!

The smell of this was so pungent that my mare would not eat her food with this product included. I tried to hide the smell some with applesauce and molasses, but she still knew it was there and refused to eat. So, I am stuck with a product I cannot use.

Smells funny, had to add water for my horse to eat it :D

Not a bad product, tried it for my horse’s allergies. Seemed to make his cough worse. Farnam cough free works better for him. :)

I have been treating my horse for a week with the HistAll allergy relief powder and see no change or improvement. The reason I purchased this product is for the biting flies and insects that plague the southeast during hot summer months. I am going to give this product a month to see if it helps. As of now, not seeing any results to help ease my horses' discomfort.

Great for allergies!

My mare has terrible allergies but this helps keep her itching less and also lessens the severity of her summer itch.
