Pyometra in dogs

There are quite a few reasons you might see mucus in a dog's urine. Mucus is a sign of inflammation, which can be caused by several different things, including bacteria, crystals, and bladder stones.

These can occur in dogs of any age, including puppies.

If your dog has mucus in their urine or is showing any other signs of a bladder infection, your veterinarian can help you determine the appropriate course of treatment.

This is especially important because bladder infections are just one type of urinary tract infection (UTI). Your dog could also have an infection elsewhere in their urinary tract, which may cause kidney disease.

Jelly like substance dog urine

Recurring infection can cause bladder or kidney stones.

Your dog may have an infection even if you aren't seeing a jellylike substance in their urine. For example, your dog may have cloudy urine and may strain to urinate.

You might also notice that they are licking at their genitals frequently. If left untreated, bacteria from an infection can move further up the urinary tract into the ureters and kidneys.
