Let’s talk a little about Urinary Tract Infections (UTIs) in dogs and cats.
A UTI occurs when bacteria travels up the urethra and into the bladder. Urine in the bladder is sterile, but once bacteria get up there, they can grow and reproduce, causing a UTI.
Common signs of a UTI could be frequently urinating in small amounts, straining to urinate, may cry or whine while urinating, frequent ge***al licking, or blood noted in the urine. For cats, urinating outside the litterbox could be a red flag, while for dogs, unusual urinary accidents in the house could be a sign something is wrong.
If there is any suspicion of a UTI, we will recommend you bring in a urine sample for a urinalysis. A urinalysis will check for: how well your pet is concentrating their urine, PH level, ketones, glucose, blood, protein, crystals, and bacteria.
If there are signs of an infection, the urine will be cultured to test what kind of bacteria is causing it. Once that is done, they will do a susceptibility to let us know which antibiotic works best for the specific bacteria.
We cannot prescribe antibiotics without doing these tests. While there is a major concern for antibiotic resistance, there are also many different kinds of urinary tract infections and they do not all react the same way to the same antibiotic. If your pet is uncomfortable, talk with the veterinarian about potentially getting pain medication while waiting for the test to be complete.
Some pets are predisposed to UTIs. Certain medical conditions such as diabetes mellitus, kidney disease, cushings’s disease, bladder cancer, and immune-compromised pets can have an increase of infections. Pets with bladder stones are also more prone to recurrent UTIs.
Certain anatomic issues can also predispose a pet, such as ectopic ureter, a recessed v***a, or obesity.
If the UTI is not treated, your pet will experience prolonged discomfort. Complications can occur, such as bladder stones or kidney infection.
