Dog Cathartics and Laxatives
Drugs that promote defecation may be classified in a variety of ways according to their severity (mild, medium, violent); their natures (oils, salines, glandular stimulants, and so forth); their action (lubricants, bile-flow stimulants); and so on.
Castor oil is a fairly quick-acting cathartic. Dogs defecate about two hours after dosing. The stool is not fluid but only slightly softer than normal, unless overdoses are administered. Castor oil should be given on an empty stomach for the best results. The dose for a forty-pound dog is one half to one teaspoonful. Remember that in giving castor oil you are not trying to lubricate the intestinal tract, but that an irritant acid is causing a speedup of evacuation. Racinic acid does the physicking; the oil is partly digested.
Mineral oil, in contrast to castor oil, when given orally is almost all deposited with the feces. It is a lubricant. Larger doses may be given, but overdoses are inadvisable because they run out, and dogs sometimes will lick themselves and thus take feces into their stomachs. Over dosing is common. Some dogs will often lap mineral oil out of a dish. They may not refuse it if it is thoroughly mixed with their food. There is little difference in the cathartic effect of the light and heavy mineral oils. Two teaspoonfuls is the dose for a forty-pound dog.
Long-continued use of oil is not advantageous, since it dissolves the fat-soluble vitamins out of the food, preventing their absorption.
Milk of magnesia is magnesium hydroxide, one of the mildest of the cathartics. Less than so percent of milk of magnesia is hydroxide. It is therefore a moderate laxative. Doses of a teaspoonful produce laxation in a forty-pound dog in about six hours. Overdoses do little harm but do retard digestion because of their reduction of stomach acidity. In pets, the pill form is seldom satisfactory.
Epsom Salts would be an excellent cathartic for dogs were they not so intensely disliked, even in solution, because of the bitter taste. Several theories have been advanced as to how the salts accomplish their results. Probably they do it by drawing large amounts of water from the intestine (osmosis) and, by thus filling the intestine, soften the contents and mechanically stimulate its action.
The dose for a forty-pound dog is a teaspoonful, usually partially dissolved in water. Its action is fairly rapid, with evacuation occurring in two to four hours after dosing.
Usage of Cathartics and Laxative
- The laxatives are generally used to bring relief to acute constipation due to non dietary consumption of food.
- The laxatives are also used as detoxicating agent. The laxatives are administered to animals to clear the gastrointestinal tract.
- The prevention of tenesmus or the advanced stage of pregnancy or prolapse.
- The laxatives are also administered post surgery or radiography to clear up the entire bowel.
You may take the help of the laxatives for the above mentioned reasons for your dog but you are recommended not to make use of them in bulk. This would rather cause deterioration of the health of your pet dog. You may consult a vet doctor before you administer the laxative medicines for your dog.
