As many of you are aware, one of Dr. Butters’ special interests is equine dentistry. Knowing this, one of our fantastic clients generously provided us with a wonderful and very interesting skull specimen that we wanted to share.
This skull is from a stallion that lived in a wild/feral state west of Cochrane. Our client knew the stallion, and relayed that he died during the very cold, deep snow winter we experienced several years ago.
Dr. Butters believes she knows what may have contributed to this early death.
Euthanasia is a term that comes from the Greek language and translated into English means “good death.” The most common method of euthanasia is via a lethal injection of a barbituate drug, but other methods may also produce a “good death.” There are many reasons for an owner to choose euthanasia and the decision to euthanize a horse is often a difficult and deeply personal for the owner.
What is in a “3-Way” vaccine? A “4-Way?” “5-Way?” “6-Way?”
We get a lot of questions about these confusing terms! The “3-Way” vaccine has long been used to describe the combination vaccine containing Eastern Equine Encephalomyelitis (EEE), Western Equine Encephalomyelitis (WEE), and Tetanus. For a “4-Way,” add influenza to those three vaccines just listed. A five way provides protection against EEE, WEE, Tetanus, Influenza and Equine Herpesvirus (“rhinopneumonitis”), and a “6-way” contains all 5 components of a 5-Way, plus West Nile. Although there is a combination vaccine that includes EEE, WEE, tetanus, and West Nile, the combination of EEE,WEE, tetanus, and influenza was on the market for years prior to the introduction of the combination with West Nile, so the “4-Way” term is usually reserved for the vaccine containing influenza and not West Nile. Clear as mud?
Contact the clinic and we can help you determine what vaccinations are appropriate for your horse. Stay tuned in the coming days for more information on these diseases and why we vaccinate against them, as well as more answers to your frequently asked vaccination questions.
Whether this is your first adventure into the world of mares and foals, or you have been down this road before, you may be wondering what happens between the time you say your farewells at the clinic and the time you get that wonderful news. Well, wonder no more! In this article I will explain all of the techniques, technologies, and tricks we have at our disposal to make the process as reliable and smooth as possible.
Wireless inertial sensor-based technology is at the forefront of lameness evaluation research today, and we are excited to now be incorporating this cutting edge diagnostic tool into our lameness examinations! The Equinosis Lameness Locator is the result of over twenty years of gait analysis research, and it allows objective quantification of lameness during a routine clinical exam.
An enucleation is the surgical removal of a horse's eye. There are many indications for which this surgery would be performed, including trauma, neoplasia (cancer), extensive infection, or any condition causing pain in a blind eye. In Misty's case, the procedure was recommended due to an acute worsening of uveitis and ulceration along with equine recurrent uveitis flare-ups that had been occurring over the last four years.
Sarcoids are the most common tumour that occurs in horses. They are locally invasive, and difficult to deal with because recurrence is common even with aggressive therapy. One study showed that 14% of sarcoids occur exclusively in the periocular region (near the eye), and these tumours can be particularly tricky to deal with as it is difficult to get good margins to remove all tumour cells during surgical excision.
In horses, the third eyelid is prone to developing squamous cell carcinoma. Squamous cell carcinoma is the second most common tumour in horses, and it is the most common tumour in the equine eye. It develops most commonly on areas lacking pigmentation, poorly haired regions, and skin near mucocutaneous junctions. It can be quite an aggressive tumour, spreading to nearby tissues and local lymph nodes. In the third eyelid, it often initially appears as a reddened area, then becoming raised and in some cases developing a wart-like appearance. In most other areas, recurrence is extremely common unless surgical excision is combined with another treatment such as chemotherapy or cryotherapy. Fortunately, the third eyelid can be removed in its entirety, and a success rate of 90% has been reported with removal alone.
