Rabies Vaccination

posted by Horse Owner Today    |   April 28, 2011 10:04

Q:  "Should I vaccinate my horse for rabies?"  I recently read that there are rabid horses in the southern U.S. this year.  I thought rabies was a disease of skunks and racoons, not horses.

A:  Rabies is a sporadic disease but endemic in Saskatchewan mostly in skunks and bats.  We have on average ten cases of confirmed wild animal/domestic animal rabies per year in Saskatchewan.  If it happens to be your horse this is very unfortunate especially if human exposure occurs necessitating rabies shots.  Again with risk assessment I would likely vaccinate any horse that you couldn't possibly live without.



Brain Worms???

 Q:  We live in the Hudson Bay area, recently a moose was put down.  The wildlife officers later informed us that the moose had "brain worms", resulting in its demise.   What are brain worms? 

We run a cow calf operation and a breeding herd of horses, do brain worms affect horses?

A:  Brain worms are a parasite found endemic in deer populations.   Pneunostrongylus tennuis, which will kill moose are likely.   This parasite does not affect horses at all.


Anthrax Spores in Hay Crop?

posted by Horse Owner Today    |   March 16, 2011 07:10

Q1:  I have heard that if hay is harvested in an area that has had anthrax previously, this hay can have anthrax spores in it.  Is this true?”Hay from an anthrax area has the chance of having anthrax spores in it and if you source hay from suspect areas you should vaccinate.  On the other hand if you have hay from sloughs and flooded haylands where anthrax has been recently diagnosed you should not be selling it.


Q2:  "If this is true, then I will need to vaccinated my herd to prevent them contracting anthrax even though I live in an anthrax free area”


A:  "Hay from an anthrax area has the chance of having anthrax spores in it and if you source hay from suspect areas you should vaccinate.  On the other hand if you have hay from sloughs and flooded haylands where anthrax has been recently diagnosed you should not be selling it."


Alternative Vaccination site for Anthrax

posted by Horse Owner Today    |   March 16, 2011 06:37

Q:  Where is the best place to vaccinate the animal?  The anthrax vaccine can cause swelling and soreness at the vaccination site.   I have heard that vaccinating in the chest is an option. 

A:  Vaccinating in the chest is a good option, just in case you get swelling and edema/abscess.   Swelling and edema/abscess are easier to deal with in the chest muscle.   

Reining issues pop up when the neck vaccination site has either/or swelling and edema/abscess occur.






Dr. Domoslai on anthrax in 2011

Q:  I found the following notice that begins "The CFIA is urging livestock producers in the Prairie provinces to take the necessary precautions to protect their animals from anthrax this summer........."What is your advice to horse owners?


A:  If you are within 5 miles of a location that has previously had anthrax diagnosed in the past 10 years or are connected by a flood plain or river system that is connected to an area that has anthrax in the past ten years or are planning on competing or riding in an area with anthrax previousley diagnosed  it is highly recommended to vaccinate for anthrax.  The vaccine is cheap and safe for all horses however the vaccine is irritating and may cause localized swelling/ abscess and it can cause death in some ponies.  If you have never had anthrax in your area then the option is yours and remember that over the past years tetanus and WNV has killed way more horses than anthrax has ever killed.





Fall Veterinary Questions

posted by Horse Owner Today    |   October 6, 2010 07:44


Q:  When should I deworm my horse? 


A:  Worm your horse after a good hard frost.  The frost will kill all bot flys which will lay eggs on your horse as well as reducing any chance of late hatching of oocytes in the pasture getting ingested.


Q:  When should I blanket my 18 yr old Thoroughbred mare. 


A:  Start blanketing when temperature drops below around 5degrees C at night or the days are cold and wet.  Make sure that in fall the blanket is removed when temperatures rise in the day to reduce the chance of sweat itch/molds occurring.  As soon as the temperature is consistently below 10 degrees C keep the blanket on continuously.


Q:   I am having a hard time weaning my foal who is six months old.  


A:   Is it important to wean them or will the her mother do it naturally.  In the wild a mother will generally wean its foal on it's own depending on the size of the foal and the available nutrients.  If the mother is fed adequately and has sufficient energy reserves and isn't pregnant she may not wean her foal.  Weaning is an important part of the development of the foal and the recovery of the brood mare and therefore it is very important for you to wean the foal.  Weaning is accomplished through a one to two month enforced separation.
