Canine Eclampsia, also erroneously called "milk fever", is a startling and dangerous condition brought on by extremely low levels of calcium in the blood stream. Also called hypocalcemia and puerperal tetany, I consider these episodes emergencies sA proper meat-based diet is the key consideration in preventing eclampsia.o the patient is admitted as soon as possible.
Most commonly seen in small to mid-sized bitches a few weeks after whelping, this condition should be watched for closely. A typical call to my office goes like this:
"Doctor, my four year-old Schnauzer whelped five puppies two weeks ago. She was fine until today when she started pacing and didn't want to nurse. Now she's worse and panting, shaking all over, and can't even stand up."
The following is a brief outline of what the typical case of Canine Eclampsia looks like:
Signs:
Muscle tremors, restlessness, panting, incoordination, grand mal seizures and fever as high as 106
Causes:
Hypocalcemia (low blood calcium) brought on by the following:
1. Poor Nutrition - "Home brewed" diets usually are at fault. The owner innocently may be adding too much unbalanced meat to the bitch's diet, thinking the extra protein is beneficial. What's really happening is the calcium to phosphorus ratio is out of balance because the amount of useful calcium in the food is actually reduced! The ideal contains a ratio of calcium to phosphorus of 1.2 to 1. (Many organ meats such as liver have a ratio of calcium to phosphorus of 1 to 15!! Liver is great for dogs but if it comprises a large part of the diet, the calcium/phosphorus ratio of the diet will be improper.)
2. Low Blood Levels of Albumen - Dietary protein deficiency or excessive loss from the body of albumen, which happens in some kidney diseases, will cause low levels of calcium.
3. Disease of the Parathyroid Glands - This condition is quite rare.
4. Excessive Milk Production - When pups require large amounts of milk (10 to 30 days post whelping) the bitch's ability to maintain proper amounts of calcium in her blood stream becomes stressed. Milk production has priority over the blood stream for calcium!
Treatment:
Quick iv medication is important in treating eclampsia.1. I. V. Catheter for a slow, careful injection of a calcium solution under the close supervision of the veterinarian. Give too much and severe cardiac arrhythmia may occur.
2. I.V. dextrose for quick energy. By this time the bitch will be thoroughly exhausted due to the muscle tremors and a quick supply of energy is very helpful.
3. Mild sedation may be required.
4. Cool bath to lower body temperatures to normal.
NOTE: If there is time, your vet may take a blood sample prior to treatment for a thorough analysis of the bitch's blood chemistry. Quick action is very important and careful administration of medications is required. Generally, the patient stabilizes within ten or fifteen minutes and the temperature is reduced to normal via the cool bath.
Prevention:
1. High quality meat-based quality food but don't over supplement with all sorts of Calcium or unbalanced meat products.
2. Add a balanced source of calcium, phosphorus, and Vitamin D to the bitch's diet beginning about mid-term. The best sources are milk (withdraw if this causes a loose stool) or cottage cheese. DO NOT add calcium alone!! It MUST be used with phosphorus and Vitamin D. (Remember that optimum ratio of Calcium to Phosphorus of 1.2 to 1!)
3. Sometimes cortisone is very helpful in preventing Canine Eclampsia - ask your veterinarian about having some on hand prior to the next whelping.Click to visit the Pet Store... Enjoy!
4. Supplement the puppies' intake with a milk replacer as soon as possible to decrease the milk demands on the bitch.
5. Wean the pups as soon as possible.
Canine Eclampsia... Hypocalcemia... Puerperal tetany... Milk Fever... fancy names for a not-so-fancy disorder. Be on the alert and call your vet if you become suspicious your bitch is having trouble. Never underestimate the importance of a high quality, meat-based diet for your dog.
