Most veterinary ultrasound machines come with gestational age calculation packages inbuilt. Within any one species, however, results are not universally accurate across all breeds. There can be huge breed variation, with some species (e.g. goats) and some breeds (e.g. chihuahuas) suffering more than others. Vieira et al.’s 2020 study sought to improve the accuracy of gestational age calculations in chihuahuas – a small dog which, nevertheless, has a large head in comparison to its body size. As chihuahuas are at increased risk of complications during delivery, it is important to be able......

Umbilical artery Doppler

Summary The resistance index is quick and easy to calculate on ultrasound machines with PW Doppler capability. Obtaining useful readings from the umbilical artery in dogs takes a lot of practice, and should be obtained from the mid-cord to ensure reproducibility. The resistance index will fall 12 hours prior to delivery, falling further 1-6 hours before, so can be used to predict when labour should begin. If the resistance index falls but labour does not follow, this can alert the breeder or vet to the possible need for veterinary intervention. M-mode can......

rabbit ultrasound scan

How early can I scan a rabbit? Positive confirmation of pregnancy has been documented as early as 7 days in rabbits, but only by the presence of fluid inside the uterus, which is a sensitive but not specific sign of pregnancy: in other words, you’ll always see it in a pregnant rabbit, but you could also see it in a rabbit coming in or out of season, or when something is wrong. It is also worth noting that in such studies, rabbits were completely shaved and mechanically restrained on their backs. While......

We have been asked by some of our members for clear guidance on ultrasound scanning for pregnancy during the Covid-19 pandemic. Our guidance echoes that of the government, in that all non-essential travel and human contact should be avoided at the present time. This includes contact with pets even without the presence of the owner, as the virus could be transmitted from one human to another on an animal’s fur or harness. There is also new evidence to suggest that animals are becoming infected with the virus. While they may fare far......
