Q: Our big mare, has been lame for 2 days. Had the farrier out this morning and apparently a deep abscess blew and her a toe is now cracked. He cleaned it out and wants us to soak it in Epsom Salts and Iodine twice a day for three days. This is NOT an easy mare to get to stand still for treatment. Would love suggestions how to keep her still.
A: If your mare won't stand still for soaking, make a poultice paste of epsom salts and a little betadine solution . Use some gauze to wrap it in to make a little pack. Use gloves if you don't want yellow/brown fingers. Apply to area of crack/hole and wrap in place with vetrap over whole foot including up over heels. You can leave this on all day then rinse out with a quick swish in a pail and redo for the night. In summer I reinforce with duct tape but is slippery in winter.
If you prefer to use the soaking technique you may have to spend more time repeatedly replacing her foot until it bores her and she gives up or apply a twitch and/or use a chain until she learns to stand even if she would rather not. I don't like the feeding her grain to distract her technique as horses get even more irritated and fidgety when you are working on them when they are eating and it distracts from the work of training your horse to comply with nursing care.

Q: My horse has a bad case of thrush, I have been usuing many different store bought remedies to cure it but it seems to only be gettting worst.. what home rememby can i use... ? thanks Devin
A: First the black infected soft horn tissue has to be removed with a hoof knife by a skilled individual, preferably your farrier. Then scrub out well with betadine or chlorhexidine scrub or even dandruff shampoo. Rinse and dry with a towel. If you put any medication on top of the dead tissue and the discharge it will not get to the origins of the infection and will not work. After this preparation you can apply the thrush treatment.
Then if copper sulfate hasn't worked [the most common treatment-coppertox] you can use bleach one or maybe two times, using a small brush to get it into deeper areas .

I am addressing this question perhaps more as a dressage trainer and teacher than as a veterinarian, so as such this is not a definitive answer, just my opinion of this issue.
Hyperflexion is a relatively recent and controversial topic in the world of competitive dressage horse training. Proponents of extreme hyperflexion are few but unfortunately several are famous and successful on the world championship/Olympic stage. They claim that flexion of the horse's jaw/head far far past the vertical for extended periods of work gives more lift to the back and more elasticity to the movement when ridden up in a more normal position during a test. There are a large majority of trainers who occasionally during schooling use an overbent longitudinal position [behind vertical, lower neck] and also lateral positions outside of the classic desired "frame". However these positions are used for seconds only to supple or unlock a resistant jaw or to prevent an evasion in another part of the body. As soon as possible the horse is returned to a normal vertical frame so that the classic goals of forward through the back and soft in jaw can be achieved with the poll, not the third vertebra or mid neck the highest point.
There are extremists on both sides [which can occupy one for hours on youtube] with some riders clearly causing physical and mental distress to the horse. In some instances permanent physical damage to vertebrae and supporting structures can occur and/or long term or permanent psychological damage including a resigned helpless and joyless horse. On the opposite side of the spectrum, other extremists vehemently state that all horses ridden in a bit are in pain at all times and are being abused.
Most reasonable horsemen and trainers love and respect horses and appreciate dressage as an art as well as a sport. They certainly fall between these extremes. I believe that realistic and fair -minded trainers are aware that at times getting a horse to comply may involve some battles of wills and bodies but we all hope this is as brief a period as possible.
It is prudent to remember that classical dressage changed very little over the past hundred + years as far as ideals and methods are concerned. Todays sport horses are bigger, more powerful, athletic and more extreme movers with each generation. It is tempting to rush these fantastic horses to the FEI levels because they apparently can, but producing a horse that keeps a sound body and mind with joy in his work for his lifetime takes as long as it ever did. When a 'new' technique surfaces, such as extreme hyperflexion, I hope that riders and trainers educate themselves, talk to people they trust and continue to use good judgement in training their horses as individuals.

Q: Dr. Domoslai, Below is a link to an article re 'Pregsure' - similar to some of the drugs in the the Pfizer Gold program that we use. Hope the MLV eliminates this problem. Have you had any cases like this?
A: Thanks for the question Peggy. I looked at all the North American data on MLV vaccines and any cases that might look like those bleeding calves from Pregsure vaccinated cows and could find nothing like that. I think that Pfizer has been pretty up front with there product lines and would let us know if there was any risk or if similar cases have been seen in North America. Sounds like an interesting distressing disease and to think that the producers who are trying to protect there cattle and do the right thing inadvertently cause the condition. Take care.

Q: Hi Dr. Domoslai, My question pertains to a 8 year old mare barrel horse that my daughter has in Altus Ok she called home tonight say her horse was acting funny tonight. she had rode her and was walking her out in the areana and the mare would stop every few minutes and try to urnaite but nothing would come out she did that about 4 times and then later on she did finally do it do you think she should be concerened... thank you
A: Not sure if male or mare from question as both were mentioned. . Males can have large "bean" of cellular and debris material in the end of urethra/penis that can obstruct or restrict urine flow. They can very occasionally have stones high up in urethra but you would notice blood in urine for weeks before obstruction. Mares rarely have trouble with urine flow as urethra is short and wide. Sometimes when horses especially geldings will stretch out like they need to urinate a few times but don't or only a few squirts. This is almost always from belly pain/mild colic. They take this posture to push out and stretch body wall to try to relieve belly pain and this increases pressure in the abdomen ant pushes some urine out. This may have been why he was acting 'funny'. Another reason could be he didn't want to urinate there some only want to go in stall or pen. He avoided it till he couldn't anymore. If urine was normal pale to mid yellow, and horse not very ill, kidneys prob fine. They are a very Rare source of disease in horses. So as you can see there can be a few causes so it is difficult to say without observing and examining the horse if this is no problem or something that needs attention tomorrow. I would say if it is only a one time occurrence don't worry too much. « Dr Lisa Wayman »

Q: Dr. Domoslai, My question today is about Oak Trees, Acorns and Horses. Would you be so kind to explain to the equine lovers why they are toxic to horses? I had no idea they were! I ask you to do this as I recenetly had a horrifying experience when my 8 yr. old gelding went from perfectly fine to nearly lame, lathargic, semi unresponsive and not keeping his penis retracted in his sheath. My farrier was the one that discovered him eating them. This drought in Texas has been tough & thankfully he is ok now. Sincerely, Teresa
A: Teresa, Thanks for the question. Acorns and the leaves and branches of the acorn tree have tannic and gallic acids which are a direct irritant to the gastro-intestinal tract of the horse. In small amounts these will not cause any problems but in large quantities can cause ulceration in the GI tract which can lead to a host of other problems one of which can be laminitis ie founder of the foot. Some horses develop a real taste for acorns and will seek them out and over consume. I’d likely fence off the trees as even though the nuts and leaves are inassessible till fall. A sudden wind storm may knock down acorns or leaves when you do not expect it and your horse may get into them. If you know your horse has over consumed acorns or acorn leaves get your vet out and they’ll likely try and coat your horses GI tract and move the offending acorns along to limit the damage.

Q: Over the past year I have heard/read bits and pieces regarding worming & the possibility that wormer may become a prescription product. Why?
A: I don’t think the generic wormers will ever become prescription products but if newer stronger generation wormers become available they often will be scheduled as prescription products due to the risk of indiscriminate use. A good example of this are the wormers that have been developed to kill round hook and tapeworms. Many people will purchase the “plus” product simply because it is more expensive or kills more worms even though tapeworms are not common in horses. If the product is sold only through veterinarians the proper indications for it use can be given and the product can be used properly.
Q: We are having frost every night, what is the best worming strategy for pasture horses in fall.
A: In Saskatchewan a good Ivermectin based wormer for the fall should be given any time now. For young weaned or yearling horses and follow up treatment should be given in a month.

Q: I had a 1 year old warmblood gelding come board in the spring and at that time he had warts on his nose. They have since gone away but now my 1yr old and 3 yr old warmbloods have warts all over their noses and spreading. Are the warts contagious? Is there anything I can do to help get rid of them. Will they go away?
A: They will go away on their own. They may be somewhat contagious if they rub noses but only young horses are susceptible. You can speed up resolution by crushing one with pliers which may alert the immune system to clear them. Other home remedies like toothpaste and other concoctions have no active ingredient against the papilloma virus but the act of applying them likely disrupts some of the lesions and acts the same as crushing. ~Dr. Lisa Wayman~

Q: My question to you this morning is this. What are the side effects of equine vaccines? I. E.: rabies, west nile & evwt-fr. Thanks
Answer by Dr. Lisa Wayman: Side effects are rare [a few out of hundreds] and the same horses often react each time more than others. A local inflammatory reaction can occur which is a slightly tender flattened lump at site of injection if present will be there the next day. This subsides in few days with bute or no treatment. Some horses get muscle soreness in whole neck after injection so much that they are too painful to raise and lower head. Those ones should be vaccinated in hind end or get bute at same time. Any injection through non sterile skin can cause an abscess that will show up and enlarge over a week. When mature this abscess is opened and flushed by vet. A very few will have an allergic reaction manifested by shaking, depression or collapse. This happens within 5 min. If a vet gives vaccination injection they will be able to give emergency drugs as soon as it occurs to reverse the allergic shock, but is rare enough than owner vaccination of own horses is not irresponsible. This kind of response can occur with any drug injection not just vaccines.
I like to give vaccines in the soft muscle in front of the shoulder rather than higher up neck. I find far fewer sore swellings at this location.
Answer by Dr. Domoslai: Vaccines have all been extensively tested on numerous horses prior to the release for sale and are extremely safe. A risk does exist and an occasional horse will have an adverse reaction. These reactions can vary from mild swelling and pain to death. An anaphylactic response is the most severe side effect of vaccine and I always have on hand, epinephrine in case the horse has an allergic response. If your horse has had adverse reactions in the past all booster shots should be risk assessed with your veterinarian before giving them. There have been many rumours and anecdotal reports of wild side effects basically blaming vaccination on everything from worms to poor behaviour and these reports have to be taken with a grain of salt. Generally speaking the side effects of vaccine are that the horse gets great immunity to many potentially fatal diseases and you get peace of mind that your horse has protection.
