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.

Q: I am wondering what you can tell me about thrush. I have 4 horses in a field that still has damp areas from all the rain this summer. I have noticed a slight smell coming from their feet and I think it might be thrush. How can I tell if it is thrush and if so what is the best way to treat it. Also what happens if it is not treated?
A:Thrush is a fungal infection of the frog. It is seen most often in wet conditions or in overgrown crack filled feet. Clean the foot and trim away any excess frog and treat the dried foot with a topical antifungal agent like Coppertox or Coppercare.
Thanks, Dr. Domoslai, DVM

EEE or eastern equine encephalitis is found usually in eastern half of North America. WEE or western equine encephalitis is the form that affects usually the western half of the continent. Both are most often mosquito and biting insect-borne, humans are also occasionally affected with encephalitis through bites from affected mosquitos.
It is a later summer and early fall disease and typically the same species of mosquito, culex tarsalis , carries both "sleeping sickness" and west nile virus.
The core horse vaccines in our area (Western Canada) have always protected horses from tetanus and EEE and WEE. This is the old "3 way" vaccine. For several years now the core vaccine also includes protection from west nile virus. (4 way or combo vaccine).
Vaccines in the south and southeastern states also protect against VEE, or Venezuelan equine encephalitis.
Outbreaks occur when owners fail to vaccinate weanlings in a herd with a series of 3 vaccines or If many horse owners in an area do not vaccinate or boost annually for years and the procedure falls off the horse culture's radar, especially among novice owners. In addition outbreaks are worse in years when there are more insect vectors and birds who amplify the virus (raise the level of infected insects) Typically EEE is more often deadly than WEE. . I saw some cases when I worked in Virginia and it is very sad to see an incapacitated and unreactive horse.
The take home message is that If horse owners in our area vaccinate adult horses in late spring to mid-summer with a core vaccine booster and complete weanlings vaccine series they have protected their horses even in the face of outbreaks. Foals should be vaccinated at 3, 4, and 5 months, If mare was not boosted with vaccine a month before foaling and 4,5 and 6 months, If mare has been vaccinated a month before foaling. Adults not previously vaccinated require 2 Vaccines 4 to 6 wks apart before July. And all horses yearlings and up require annual boosters.

Q: I got bit by a say wild kitten on 9/16. Our cat had the kitten but it hadnt been around and just showed up on the porch so I picked it up, it was scared because its not around people. The kitten bit my finger 3 times, drew blood all 3 spots, not deep. in fact it healed by say the next day. the kitten looked healthy. i seen it also 4 days later and it looked healthy. no pain at the bite site. But i havent seen the kitten since then. Coincidence or not, i started having back pain and now a lymph node in my neck is swollen. Should i be concerned about rabies or anything. I did not go to the doctor for this.
A: Definitely go see your MD. Tomorrow. Not so much for rabies risk although possible. Sounds like infection from tiny punctures from cat teeth and claws that harbour many bacteria and are too small to clean out properly. Your lymph node is enlarged because it is trying to produce cells that will fight off the bacteria. You will prob need antibiotics or can get bad quickly. If rabies on list you need to get hyper immunized ASAP that means rabies vaccine every 2 weeks for several times. Don't wait and see.

Q: Hi Dr.Domoslai, we are looking at purchasing our first horse for our 12 year old daughter. She wants to start jumping and the horse we are looking at is a cribber. But he is a real sweet heart and my daughter loves him. However we are not 100% sure if this would be a wise investment?? If you could help us out, that would be most appreciated. Thanks so much.
A: Thanks for the question. Cribbing is a life-long issue that requires continual intensive management, with the potential for a multitude of other health issues cropping up that are directly related to the cribbing. I would consider alternate horses before making a final decision on this one. Potential options include, perhaps a 3 month trial with a total return of the horse pending the cribbing issue.

Q: What is the best way to treat scratches on a horse. Both back feet...it doesn't look really bad but enough that he doesn't like me touching it. I was thinking of putting a rope around the back feet and rubbing that back and forth to rub it off instead of trying to lift the feet and scrape it off. But what is good to put on it after? I've heard bleach but ?? What do you suggest is the best to get rid of it quickest and easiest. Thanks :)
A: Scratches is a complex disease of non-pigmented skin as it reacts to light, moisture bacteria and fungus. It is best treated with a compounded ointment that will address all of these areas. I have not found one that works good commercially and therefore we make one up with all the secret ingredients. The lesion needs to be scrubbed free of all scabby areas and the lotion applied daily for a few weeks.

This gelding is being treated with mineral suppositories and oil drenches
September 8, 2011 21:19
This young gelding presented with weight loss and a toe dragging hind legged lameness. Notice the slight rise in the croup area and the buttress toed hind limbs. An interesting note is that he has been consuming the tails of his pasture mates. He is the only long haired horse remaining. We suspect a Phosphorous/Calcium deficiency leading to irregularities or injury to the lumbar region of the spine. Concurrent with this is a possible cecal hair ball accumulation.
October 4, 2011 update. This gelding was treated with calcium and phosphorus minerals, drenched with mineral oil, no cecal hair ball accumulation has been dislodged. Coordination is degrading, if the gelding is led over a rail and can see it, he will lift his feet over. If he is led over the same rail, unable to see the rail, he will stumble. Physical condition is slowly degrading.
