Frequent attempts to urinate

Excessive Gas
Heavy internal parasitism
Excessive ingestion of sand
Pedunculated lipoma (fatty benign tumor of the gut which restricts flow of ingesta)
Enterolith or fecalith (stones in the digestive tract)

-Banamine is given to reduce pain
-A nasogastric tube is inserted to release gas and fluid
-IV fluids if horse is dehydrated
-If impact collic, laxatives can be given to release the impact
-If there is a twist in the bowel then surgery will have to be done to untwist the bowl.
One of the most common respiratory disease in horses and is not curable. Thick mucus is made in the horses lungs due to pollen or other allergen substances and as time goes on it gets thicker and causes the horse to cough and have trouble breathing.
This disease is brought upons because of allergies. Most common in older and mature horses it is much like asthma in humans. Pollen or dust can cause Heaves.
-Increased breathing rate (respiration)
-Nasal discharge
-Abnormal lung sounds
-Weight loss

-Limit horse as much as possible from allergens.
-Inhaled corticosteriods: These are medications that control the inflamation in the lungs
-Inhaled bronchodilators: Medication to open airway passages.
Large Strongyles (bloodworms, redworms, palisade worms)
-can cause fatal colic if untreated and very bad. Otherwise weight loss and anemia.
Roundworms (ascarids, large roundworms)-
caughing, pneumonia, liver damage, diarrhea and colic.
Tapeworms (cestodes)
-colic, rough hair coat, slow growth, weight loss.
Lungworms (Dictyocaulus arnfieldi)
- respiratory problems and caugh.
Pinworms (Oxyuris equi)
- rub tail until hair is gone. Very itchy. Found around anal area, may have clear discharge.
Bots (botfly larvae, Gasterophilus nasalis, Gasterophilus intestinalis)
-implant eggs
Strangles is a highly contagious and serious infection of horses and other equids caused by the bacterium, Streptococcus equi.
-Susceptible horses develop strangles within 3–14 days of exposure. (2)
-Nasal Discharge- thick
-More typically of strangles
-Soft cough
-Swelling or hardening of lymph nodes
-Horses are often seen positioning their heads low and extended,

Founder is a disease of the laminae of the foot.
There are acute and chronic forms of ofunder

-Horse getting into the feed bin and eating too much
-Gram negative bacterial infections with endotoxemia
-Excessive concussion to the feet
-Standing on black walnut shavings
-A hot horse drinking too much cold water too fast

-Horses steps shorten and sometimes cease.
-Prop feet out ahead of him and push back, leaning on
rear feet.
-Shift weight back and forth
-Spend time laying down and off of thier feet
and bute (pain killer)
-Trimming and shoes
-Soaking the feet

Strangles is caused by Streptococcus equi subspecies equi, better known as Streptococcus equi (S. equi). The organism can be isolated from the nose or lymph nodes of affected animals, and is usually readily identified in the laboratory by simple sugar tests.
If the disease is more advanced, then most veterinarians will not use antibiotics but rather will recommend nursing care and trying to hasten the development of abscesses (which can be drained) by poulticing. Antibiotics may, however, be used if complications arise.
Nasal discharge
Leaning back on rear hooves.
