Ultrasonograms of the extra-fetal structures in pregnant Miniature Schnauzer bitches. Day 18: Transverse image of the first detection of an anechoic gestational sac. Day 21: Longitudinal image of the gestational sac. An echogenic inner placental layer was detected in the uterine wall. Day 27: Longitudinal image of the gestational sac contained an embryo and the tubular shape of the yolk sac membrane (white arrows). The zonary placenta (white arrowheads) was cylindrical in shape and appeared folded inward at the edges. Day 28: The amnionic membrane (white arrows) appeared faint.

Ultrasonograms of the fetal structures in pregnant Miniature Schnauzer bitches. Day 23: Transverse image of the gestational sac contained an oblong-shaped embryo (white arrowhead) apposed to the uterine wall. Day 32: Longitudinal image of a fetus with an anechoic area in the head and forelimb buds (white arrowheads). The fetal crown-rump length was 20 mm. Day 38: Longitudinal image of a fetus with hyperechoic skeletal structures in the head and thoracic wall (white arrowheads).

Gerät mit einem  PW Doppler. Die Sonde liegt auf dem Herzen eines Hundewelpen. Der Herzschlag des Welpen ist über Lautsprecher  zu hören und auch grafisch dargestellt  (die Zacken auf der unteren Linie). So kann man bei einer Geburt beurteilen, ob es dem Welpen in der Mutter gut geht.

Nachweis der Trächtigkeit. Sie ist beim Hund etwa vom 21.Tag möglich.

In diesem Stadium sieht man die Foeten als „Fruchtampullen“ und kann recht gut ihre Zahl bestimmen. In einem späteren Stadium, kann man lebenswichtige Organe wie Herz, Leber und Magen der Foeten sehen. Herzschlag und Fruchtbewegungen lassen sich schön zeigen.

Fetal death likely hemoparasitosis

3 years bitch crossed to 35 days, with bloody discharge.
In ultrasonographic examination were viewed at least six gestational vesicles with the presence of fetuses without beating with thickening of the gallbladder wall, and having at least one well-formed fetus with definition of chest to abdomen, and the other with bone formation and little definition thorax and abdomen.
It was still seen good hypoechoic enlarged spleen and liver bitch. Suggesting a possible hemoparasitosis and fetal death at various gestational stages.
In some cases hemoparasitoses (tick disease), end up very lowering the immune system, and this pregnancy is interrupted, or there may be birth defects. The hypoechoic liver also justify an acute liver disease (toxemia).
