What health conditions can be detected using ultrasound in dogs?

A range of health issues in dogs arise during their lifetime. Detection of some of these can be done with ultrasound.

Heart conditions

An ultrasound is the most reliable tool to follow up on possible heart conditions in your dog. Vets ask for this test to further investigate the condition of the heart.

Internal organ examination

Besides heart, dogs have problems with kidneys, bladder, and liver, which reflect in abnormal blood tests. A thorough examination is needed. This helps the vet arrive at the real reason behind distress.

Soft tissue health

From eyes to ligaments, from tendons to glands, dogs may experience problems from time to time. These can be accurately assessed using ultrasound.

Reasons for diarrhea

Ultrasound has been very effectively used to detect reasons for diarrhea in dogs. Determining the health of intestinal walls and detecting foreign bodies in the gastrointestinal system can be very accurately done.

Pregnancy and litter size

The most common reason for using ultrasound in dogs is determining fetal health and progress. However, it needs to be mentioned here that ultrasound does not always give an accurate count of numbers for puppies. 

Ultrasound-guided tissue collection

Ultrasound is used to assess the above and further test if any abnormality is detected. If there is some abnormality that needs further probing, ultrasound-guided tissue collection is very helpful. There is no wonder how accurate is ultrasound in dogs.

How accurate are ultrasound results in dogs?

As mentioned above, pregnancy is the most investigated issue in dogs for which ultrasound is used. In this context, one needs to know how accurate is ultrasound in dogs.

Predicting puppy numbers

Ultrasound is passably accurate in predicting the number of puppies in a litter. Usually this number is correct in about 90% of cases up to +/- 1 pup. An owner can have a good idea of how many new puppies are expected in each pregnancy.

Fetal organ development

Ultrasound gives an accurate picture of fetal organ development for bitches. This is assuring for the pet parent and ensures a healthy pregnancy for their pet bitch.

Parturition date prediction

Very good accuracy of parturition date prediction is done using ultrasound in bitches. This is close to 86% within +/-2 days of 65 days.

Gestational age prediction

Gestational age prediction is made pretty accurately using the ultrasound method for bitches. Diameters of the head and trunk are evaluated using ultrasound. The forecast is seen to be accurate irrespective of litter size or maternal body weight.

How to prepare your canine for an ultrasound?

Preparation will depend on which body part is being subjected to ultrasound. It is advisable to consult with your vet in this matter. Generally, sedation is not needed if your dog is cooperative, but sometimes light sedation helps. In some instances of ultrasound-guided tissue collection, heavier doses of sedation might be required for your pet.

The area to be tested will need to be shaved, which is done at the vet’s office for clearer pictures. Other preparations might include your dog needing to go without food and water for 8 to 12 hours. Having a full bladder is recommended for more accurate ultrasound results.

Whatever the reason for an ultrasound for your dog suggested by your vet, you may rest assured that it is a good and pretty accurate investigative tool!
