What is the specific gravity reading on your pet’s urine test?

The specific gravity (SG) reading on your urinalysis test is a measurement of the ratio of the urine to the weight of an equal volume of water.  It is a reflection of the ability of the kidneys to concentrate urine.

Your dog and cat’s specific gravity will vary throughout the day.  With exercise and no intake of water, the urine becomes more concentrated.

Normal readings are as follows:

cats:  1.015 to 1.060

dogs: 1.015 to 1.050

Dilute urine is on the left side of the color chart and becomes more concentrated as the values go up.

Consistent low levels of specific gravity can indicate diabetes insipidus, impaired kidney function, adrenal gland abnormalities as well as over consumption of water.
