Apple seeds are actually toxic to horses, but they have to eat about a cup or more of just plain seeds !!

Beware of pokeweed! Usually horses won't eat it because it's too bitter, but my guy was in drylot to lose weight and insisted on nibbling it through the fence. He kept colicing and we couldn't figure out why. We got rid of the pokeweed, no more colic!

Poisonous plants - an Ounce of Prevention

I have a section on poisonous plants in my just released e-book An Ounce of Prevention, How to Stay Safe with Horses. I gathered stories of wrecks from horse people throughout the country so people could sit in a comfortable chair, read about them and not make the same mistake. I've posted some information below that I hope will be helpful.
I'm also looking for people to review my book on amazon and will be happy to send a free file (either to read on your computer or on an e-book reader) if you'll contact me at sinclairbrowning.com. I've had horses for over 50 years and wrote the book Lyons on Horses with trainer John Lyons.

If the horse is stabled in an open area, such as a pasture, care must be taken that there is nothing poisonous within the horse's reach. Years ago we bought a property that had an entire pasture fence line decorated with oleanders, very toxic bushes. While horses had been stabled here for several years without incident, I was not willing to take the chance and we pulled the plants out.
It can be argued that only a starving horse will eat poisonous plants. But is it worth the risk?
Trees that are poisonous to horses include apricot, black locust, black walnut, oak (and acorns), buckeye, black cherry, chokeberry, chokecherry, plum, peach and red maple leaf. And although we give our horses apples, apple tree clippings and large quantities of the fruit can poison a horse.
Common garden variety flowers can also be poisonous. Buttercups, daffodils, lilies of the valley and narcissus have poisoned horses.
While locoweed and oleander come to mind, the list for toxic bushes, grasses and weeds is numerous including: avocado, bitterweed, black nightshade, bladder pod, buckthorn, burroweed, Carolina Jessamine, castor bean, chickweed, cocklebur, cowbane (water hemlock), death camas, dogbane, fireweed, groundsel, Japanese yew, jimson, lantana, larkspur, laurel, lupine, milkweed, nightshade, locoweed, oleander, poison hemlock, potato plants (including potatoes), privet, ragwort, rattleweed, rhododendron, tarweed, yellow-star thistle, white snakeroot, wild pea and wild tobacco.
While spring and fall are the most common times for poisoning, the caring horse owner should remain vigilant all year long. Not only should all of the above plants and trees be removed from any horse stabling area, but care must be given not to feed grass clippings that may contain any of them. Grass clippings are also hard on a horse's digestive tract as they can ferment and cause colic.
Flora may be seasonally dangerous for the horse. Scrub and shinnery oak brush are poisonous, but only in the spring when they are leafing out. Persimmons, found in the southern part of the United States, ripen in late fall. Their seeds are similar to Velcro and form a mass when ingested. A horse, if he has eaten persimmons, may impact, rupture his gut and die.
Here in Arizona we have mesquite trees which, most times of the year, are fairly harmless to horses. In the summer, however, they shed mesquite beans which the horses love. Eating too many of these can lead to a painful impaction, or even death, for the horse.
If you are traveling through, or are new to, an area there may be harmful regional plants that you are not aware of. Kathy, who went to vet school in Kansas, remembers horses there eating hedge balls and choking. "Be aware of what is a problem in your area," she cautions.
"Pastures may also be unsafe for periods of time," Kathy continues. "After fertilizing, nitrates are too concentrated. After a freeze Johnson grass can be very poisonous because it concentrates nitrates and cyanide."
She also remembers some cattle in Arizona that died after eating grass. Analysis determined the grass had a high lead content. The pasture was downstream from an old mine.
Discourage neighbors or passersby from feeding anything to your horse without your consent. While trail riding do not let your horse browse on any unfamiliar vegetation.
If shavings are used in stalls their content must be checked. A Colorado stable had trouble with shavings when it was discovered that pine shavings had been mixed with poisonous black walnut shavings, which the horses ate.
In the event that your horse does become poisoned, help is as close as the telephone. The National Animal Poison Control Center at the University of Illinois hosts a wealth of information including access to veterinarians trained specifically in toxicology and a database containing over 200,000 poisoning cases. The number is 1-888-426-4435.
Dealing with all wild and domestic animals they have veterinarians on staff, at least one of whom is on call 24 hours a day.

A friend's horse (a point to pointer) suffered badly from buttercup poisoning. However, it is safe in hay, unlike ragwort.

Poisoning

It sounds like your friend's horse survived, right?

That was one lucky pony!

Yes, he survived and recovered fully, but had a nasty bout of laminitis and was
Boxed for a long time. It seems that he (as some can) got a taste for buttercups which are ubiquitous in UK horse grazing unless it is specifically treated.

Dumas' Grrrl after trying to ruin my computer screen to kill a gnat, I FINALLY realized it was just an application! I love it! Is there any way to send it to me?
