Kentucky equine has a nasal spray called breathe wise that works well for what you are needing

 

Antihistamines made a nut case with a bad attitude out of my horse with environmental allergies.

I found this and it worked miracles on him for several years.

Allergy Herbal Blend - pelletized

I used it seasonally. I put him on Remission for something else, during his off season from the allergy herbs. When Spring rolled around, it hit me that he was not experiencing his runny nose/coughing/sneezing.

He' been on the Remission and off the allergy herbal blend for three years without any flareups. His skin has also stopped crawling and the big flakes of dandruff are gone.

That reminds me: I shampoo this horse with MalAcetic, an all natural shampoo.

You can find it cheaper, than on Amazon and it does come in an 8 oz bottle. A little goes a long way. It has an almost hypnotic effect on the horses and dogs, probably because it is so soothing.

I use it sparingly, only as needed and still have the same gallon I bought in 2009:shock:


These are two more options that work on my horse, if antihistimines don't do it for yours

 

Do you have any idea what caused your horse to get crotchety?

I forgot to add this in the original post, but my horse has a history of ulcers which, fingers crossed, seem to be gone. But I'm still concerned about NSAIDs, which seem to be in many of the good herbal blends. I'll send the blend to my nutritionist and see what she thinks about it!

I'll also try and get the BreathWise . . . Might need to fight the vet for it. He's an old ranch type who doesn't believe in really medicating horses, except for bute and banamine :-| But the BreathWise looks like it could work. Remy is constantly dripping thin, clear mucus.

Btw, at the end of this video you can see what the head tossing, albeit less violent than usual: The Poor Girl's Shared Belief — Got sent this from my roommate/teammate yesterday....

 

My vet said to use Zyrtec 10 tablets a day for a full sized horse. I can't remember if it is once or twice daily...

My mare has "heaves" only during the summer. She has a very mild cough and we are just getting to the point now where she needs medication again.

 

Life can make him cranky. He is 21 and has been with me since he was 2-1/2.

He was born with attitude and the allergies compound it. I have had a couple breeders tell me, that horses who aren't disciplined by their dam, when they are little, grow up to be disrespectful and always needing discipline. I didn't know his dam, so can't say if that applies to him.

He is also a very high polled horse. My grandad cautioned me to stay away from high polled horses because "they ain't quite right" but this guy has that champagne-smooth running walk people lust after, making grandad's words a dusty memory on the back shelf in the closet:-|

At any rate, his cranky attitude came first and is enhanced by allergies. He is on a strict diet and the Remission works as good for him, as the allergy herbs did.

This particular horse also has allergies to all grains and soy. Soy is the worst.

As far as ulcers, he was checked several years back. However, in the last six months I have laid two of his lifelong buds (they were 27 & 29) to rest and he has had a melt down. If he doesn't have ulcers by now, he never will.

The farm vet will be here next Thursday to do physicals on him and my other horse, plus do some chiropractic son my other horse. She is smart and astute as a whip. Not much gets past her, if she feels this horse needs ulcer meds, I will put him on whatever she hands me

I can't get the video to open, I will try later. I am sure it's operator error
