Do you know that in 30 minutes a healthy looking nursing dog can become critically ill?
This rapid decline is often due to milk fever which can be life threatening in nursing dogs.
For dog owners, particularly those with small breeds or dogs nursing large litters, understanding milk fever is vital to prevent potentially fatal outcomes.
This blog will guide you through the causes, symptoms, diagnosis, treatment, and prevention of milk fever in dogs.
What Is Milk Fever?
Milk fever, also known as eclampsia or hypocalcaemia, is a condition that occurs when a nursing dog’s blood calcium levels drop dangerously low. This typically happens within the first 1-5 weeks after giving birth, though it can occur before or during birth in some cases. Calcium is essential for muscle function, and its deficiency can lead to a cascade of severe health issues, including muscle spasms, seizures, and even death.
Symptoms To Watch Out For!
Milk fever symptoms can progress rapidly.
Here’s what to look out for:
| Early Signs | Advanced Signs |
|---|---|
| Restlessness | Muscle spasms |
| Heavy panting | Seizures |
| Drooling | Inability to walk |
| Stiff movements | High body temperature |
| Reduced appetite | Disorientation |
| Whining | Rapid heart rate |
If you notice any of these symptoms in your nursing dog, it’s crucial to seek veterinary care immediately. Milk fever can become fatal within 30-60 minutes of symptoms appearing.
How Is Milk Fever Caused?
The primary cause of milk fever is the excessive loss of calcium through milk production, which the dog’s body cannot replenish quickly enough.
Several factors can contribute to this condition, including:
| Factor | Explanation |
|---|---|
| Inadequate Diet | A diet lacking in essential nutrients, particularly calcium, can predispose a dog to milk fever. |
| Excessive Calcium Supplementation | Paradoxically, supplementing calcium during pregnancy can impair the dog’s ability to access its own calcium stores. |
| High Milk Production | Small breeds with large litters are particularly at risk due to the high demand for milk production. |
| Parathyroid Gland Dysfunction | A malfunctioning parathyroid gland can disrupt normal calcium regulation in the body. |
| Low Albumin Levels | Low levels of albumin, a protein that helps transport calcium, can exacerbate hypocalcemia. |
Diagnosis And Treatment
The following is likely to be done if you do bring your dog to the vet and they suspect she has milk fever:
- Physical examination
- Blood tests to check calcium, albumin, and parathyroid hormone levels
- Electrocardiogram (ECG) to assess heart function
Treatment for milk fever typically involves:
- Immediate separation of puppies from the mother to stop further calcium loss
- Slow intravenous administration of calcium
- Monitoring of heart rate and rhythm during treatment
- Administration of anti-seizure medications if necessary
- Treatment of secondary issues such as hyperthermia or low albumin levels
Most dogs show improvement within 15 minutes of starting calcium therapy. However, full recovery may take several hours, and some dogs may need to stay in the hospital for monitoring.
Caring For Puppies During Treatment
While the mother is being treated, the puppies will need alternative care:
- For puppies under 4 weeks: Feed an appropriate milk substitute
- For puppies over 4 weeks: Begin weaning onto puppy food
- Puppies may be allowed to nurse for short periods after the initial 12-24 hour separation, under veterinary guidance
Long-term Management And Prevention From Milk Fever
After initial treatment, ongoing management is crucial:
- Dietary changes: The mother should be fed a balanced, high-energy diet, often puppy food, to support lactation
- Calcium and vitamin D supplements as prescribed by your vet
- Regular check-ups to monitor blood calcium levels
- Careful monitoring for signs of relapse
Preventing milk fever is possible with proper care and nutrition:
- Good Diet: Feed the mother a good balanced diet, with puppy food as needed, during pregnancy and lactation and she will get enough calcium.
- Avoid Calcium Supplements During Pregnancy: Contrary to what some might think, calcium supplements during pregnancy can lead to milk fever. The dog’s body may become less efficient at accessing its own calcium stores if it relies on supplements.
- Lactation Support: In puppies, dietary supplementation with milk replacer early in life will reduce the demand on the mother’s calcium stores. This can be huge in small breeds with big litters.
If you suspect your dog has milk fever, don’t wait—early intervention is key to a full recovery. Reach out to your veterinarian immediately to discuss the best course of action, including potential treatment options such as calcium supplementation and supportive care. Remember, the faster you act, the better the outcome for your pet.
