A small breed female dog, about 4 kilograms in weight, is suffering from eclampsia. Eclampsia is a condition wherein a female pet exhibits panting, increased heart rate, collapse and tremors because of very low calcium concentration in her blood. This dog has just given birth to a large litter three weeks ago, and is completely nursing the puppies. Actual total serum calcium concentration of this pet is 6.5 mg/dL (normal values 8.7-11.8 mg/dL). Eclampsia will occur if there is not enough calcium in the body to supply the high demand for this mineral during peak lactation. If left untreated, eclampsia will progress to coma and death.


Dirofilaria immitis is the cause of canine heartworm disease. It is endemic in most temperate and tropical coastal zones in the world. Affected animals are often between 4 and 7 years of age although the condition has been diagnosed in animals less than one year of age.
The microfilaria shown in this video is the first stage larvae. When a mosquito bites an infected dog, circulating microfilariae are ingested and develop into third stage larvae (L3) which migrate to the mouth parts of the mosquito. The third larval stage of the heartworm stage enters the subcutaneous tissues of the host via a bite from an infected mosquito.


This video illustrates a Dipylidium caninum egg packet.

Dipylidium caninum is one of the many tapeworms infecting animals. Tapeworm affecting dogs only is Taenia pisiformis, while that of cats only is the T. taeniaformis. The illustrated Dipylidium caninum egg packet affects both dogs and cats.
Dipylidium infection is flea-vectored. Flea maggots pick up tapeworm eggs in dog or cat feces. Transmission is when adult fleas are ingested by dogs or cats.
