Gotta Check That Pet Pee: Here's what you should know when you spot blood in your furry friend's pee.
Whenever you notice there's blood in your dog's urine, it's normal to feel concerned. But don't panic just yet, let's find out what's causing it.
The Scoop on Blood in Dog Pee
Blood in a dog's pee can varying appearances, ranging from a slight pinkish tint to an obviously red hue. You might also see red blood clots or specks of blood. Sometimes, the blood may not be evident unless the pee is against a light background, like when the dog pees on snow or a white floor.
The Culprits Behind Bloody Pee
There are several potential causes for this issue. Since many causes share similar symptoms, self-diagnosis isn't a wise move. If you spot blood in your dog's urine, it's essential to take your pet to the vet for a professional diagnosis and treatment.
Here are the six most common reasons for bloody dog pee:
UTIs: Ugh, Urinary Tract Infections
Urinary tract infections are probably the leading cause of blood in the urine. These are bacterial infections that affect the urinary system in dogs. Female dogs tend to be more susceptible to UTIs than males. Additionally, apart from blood in the urine, other symptoms may include pain, frequent urination, and urinating small volumes.
Kidney Infection: Ka-ching, Pyelonephritis
A bacterial infection of one or both kidneys is known as pyelonephritis. It often occurs when an infection from the lower urinary tract ascends to the kidney(s) via the ureters. While some dogs with kidney infections are asymptomatic, others may exhibit upper urinary tract signs, such as increased drinking, increased urination, kidney pain, vomiting, lethargy, loss of appetite, fever, and blood in the urine.
Urolithiasis: Urinary Stones, Ouch
Stones in the urinary tract can cause blood in the urine due to inflammation and injury to the surrounding tissues. These stones can be found in various parts of the urinary tract, including the kidney, ureter, bladder, or urethra. Symptoms of urinary stones include painful urination, frequent urination, and urinary incontinence.
Tumors: Uh-oh, Malignant Growth
Tumors in the lower urinary tract can lead to blood in the urine, as well as other symptoms like straining to urinate, more frequent urination, painful urination, and incontinence. In some cases, these tumors may also cause urinary tract obstruction, resulting in unproductive straining, pain, lethargy, and systemic illness.
Prostatic Disease: Prostate Problems
In unneutered male dogs, diseases such as Benign Prostatic Hypertrophy and prostatitis can cause blood in the urine. These conditions are common in intact (unneutered) male dogs but rare in neutered males. Other symptoms associated with prostate disease include straining to defecate, increased urination, straining to urinate, urinary incontinence, and bleeding from the penis.
Bleeding Disorders: Not Just About the Nose
While less common, bleeding disorders can be a possible cause for blood in dog urine. These disorders can be inherited or acquired secondary to other conditions, such as rodenticide toxicity. Symptoms of bleeding disorders may include pale gums, weakness, bruising, bleeding from the nose, coughing, or exercise intolerance.
Watch for Other Symptoms
If you observe blood in your dog's pee, it's crucial to consult a vet immediately. Be sure to report any other symptoms your dog might be experiencing, like straining to urinate, painful urination, frequent urination, accidents in the house, or any changes in health or behavior. Your vet will also ask you about any changes in your dog's eating, drinking, and defecation habits, as well as energy level.
Your vet may recommend several tests to diagnose the cause of your dog's bloody pee, such as physical examination, urinalysis, radiographs, and ultrasound.
The treatment for blood in your dog's urine depends on the underlying cause, and there are no effective home remedies to address this issue. It's essential not to ignore this symptom, as many causes can be serious and may progress if left untreated.
Preventive care, such as neutering your male dog and maintaining regular veterinary care, can help reduce the risk of issues causing bloody dog pee. Keep any rodenticides securely out of reach of your dog to avoid accidental poisoning.
Considering the potential implications of a dog's blood-tinged urine, it's important to stay informed about various aspects of health-and-wellness, including mental health. To maintain a happy and healthy pet, prioritizing regular veterinary check-ups can help detect underlying conditions early.
Scientific research consistently demonstrates the vital role of mental health in overall health and well-being, and for our beloved pets, that applies as well. While dealing with a health concern, like blood in a dog's urine, it's essential to remain calm and avoid unnecessary stress for the pet. Practicing effective coping strategies, such as deep breathing or positive thinking, promotes mental health and wellness for both owners and pets during challenging times.
