Dog Blood in Urine and Shaking: Causes and What to Do
When a dog shows blood in the urine together with shaking, the combination can point to pain, fever, or a more systemic problem that a veterinarian should assess promptly.
Quick Answer
Blood in a dog's urine (hematuria) is always a reason to contact a veterinarian. When it appears together with shaking or trembling, it may indicate that the dog is in pain, running a fever, or experiencing a systemic illness. Shaking can also reflect fear or nausea. Because this combination can be associated with infections, bladder stones, or toxin exposure, call a veterinarian promptly and bring a fresh urine sample if possible.

What Blood in Urine With Shaking Looks Like
Blood in the urine, known medically as hematuria, means that red blood cells are present in the urinary tract. The urine may look pink, red, or brownish, or you may notice small clots. Sometimes the blood is microscopic and only detected on a laboratory test, but visible discoloration is what most owners first notice at home.
Shaking or trembling is a separate sign that can accompany hematuria for several reasons. A dog may shake because of:
- Pain from bladder inflammation, stones, or a urinary blockage
- Fever, which often develops with infection
- Fear or stress, especially if urination is uncomfortable
- Nausea, which can occur with kidney issues or toxins
- Low blood sugar, particularly in small breeds or puppies
When hematuria and shaking occur together, the combination suggests the problem may extend beyond the urinary tract itself. A veterinarian can assess whether the shaking reflects pain, fever, or another systemic process.
What May Be Associated With These Signs
Several conditions can produce both blood in the urine and shaking. A veterinarian is needed to determine the actual cause, but common associations include:
- Urinary tract infection (UTI): Bacteria inflame the bladder lining, causing bleeding and discomfort. Fever and pain may lead to shaking.
- Bladder or kidney stones: Mineral stones irritate or abrade the urinary lining. The pain of passing or blocking urine can cause trembling.
- Urinary blockage: More common in male dogs, a partial or full obstruction is painful and can make a dog shake, strain, and pass only small amounts of blood-tinged urine. This is an emergency.
- Kidney infection (pyelonephritis): An infection reaching the kidneys often causes fever, lethargy, and shaking alongside hematuria.
- Toxin exposure: Certain plants, foods, or chemicals can damage the kidneys or alter blood clotting, producing bloody urine and tremors.
- Trauma: A fall or blow to the abdomen can injure the bladder or kidneys, leading to bleeding and pain.
- Clotting disorders: Conditions that interfere with normal blood clotting can cause bleeding in the urinary tract.
Shaking by itself is not a diagnosis. It is a sign that the body is responding to discomfort, temperature change, or illness, and it warrants attention when paired with hematuria.
What to Monitor at Home
While you arrange veterinary care, you can gather useful information to share with the clinic. Note the following:
- The color of the urine (pink, red, brown) and whether clots are present
- How often the dog attempts to urinate and whether only small drops come out
- Whether the dog cries, strains, or seems reluctant to move
- Whether shaking is constant or comes in episodes
- Appetite, energy level, and whether the dog is drinking more or less than usual
- Any vomiting, diarrhea, or pale gums
- Possible access to toxins, spoiled food, or new plants
If you can, collect a fresh urine sample in a clean container. Refrigerate it if there is a delay, and bring it to the appointment.
What to Do While Arranging Care
Call your veterinarian as soon as you notice blood in the urine, especially when shaking is also present. While waiting for the appointment:
- Keep the dog calm and warm, but avoid overheating if a fever is suspected
- Encourage access to fresh water unless the veterinarian advises otherwise
- Do not give any human or over-the-counter medications, as many are unsafe for dogs
- Do not attempt home remedies or force the dog to urinate
- If the dog is a male straining without producing urine, is vomiting, or collapses, treat it as an emergency and go to the nearest emergency clinic
When to Contact a Veterinarian
Blood in urine is always a reason for veterinary attention. The addition of shaking raises the concern because it may point to pain, fever, or a systemic illness. Seek same-day care when the two signs appear together.
Seek emergency care immediately if you notice any of the following:
- Straining to urinate with little or no urine produced, especially in a male dog
- Repeated unproductive attempts to urinate
- Vomiting, collapse, extreme lethargy, or pale gums
- A painful, hard, or distended abdomen
- Shaking that is severe, continuous, or accompanied by a high temperature
Non-urgent but prompt follow-up is appropriate when the dog is otherwise bright, eating, and urinating normally between episodes, yet blood and occasional shaking persist. A routine veterinary visit, ideally within a day or two, is still recommended.
Frequently Asked Questions
Does shaking always mean my dog is in pain?
Not always. Shaking can result from pain, but it may also reflect fever, fear, nausea, low blood sugar, or feeling cold. When shaking occurs with blood in the urine, a veterinarian can help determine whether pain or a systemic cause is responsible.
Can I wait a day to see if the blood and shaking resolve on their own?
Waiting is not recommended. Blood in the urine combined with shaking can be associated with infections, stones, or a blockage that may worsen quickly. Contacting a veterinarian the same day is the safest approach.
Should I give my dog pain medication I have at home?
No. Many human pain relievers, including ibuprofen and acetaminophen, are toxic to dogs and can worsen kidney injury or cause dangerous side effects. Only a veterinarian can prescribe safe, appropriate medication.
What will the veterinarian do?
A veterinarian typically performs a physical exam and may run a urinalysis, blood work, and imaging such as ultrasound or X-rays. These steps help identify the cause and guide appropriate treatment.
