Systemic Hypertension in Dogs and Cats: Understanding High Blood Pressure and Its Causes.

High blood pressure in dogs and cats is often more complicated than a single abnormal reading. In many of our veterinary patients, systemic hypertension develops secondary to another medical condition. That means identifying and understanding the underlying disease can be an important part of determining what is happening with your pet.

Pulmonary hypertension in dogs and cats means elevated blood pressure in the lungs, and it is different from systemic or arterial high blood pressure.

In some veterinary patients, pulmonary hypertension can develop secondary to chronic lung disease. This connection between the cardiovascular and respiratory systems may mean that both cardiology and internal medicine specialists are involved in a pet’s care.

At MarQueen Veterinary Specialty Group, our specialists can work together when a pet’s condition involves more than one body system.

Learn more about pulmonary hypertension, its connection to lung disease, and how we evaluate these cases in our latest blog post.

Vomiting and diarrhea are common reasons dogs and cats need veterinary care. While some cases may be minor and self-limiting, these symptoms can also signal a more serious underlying problem.

Details such as how often vomiting or diarrhea occurs, its severity, appearance, and whether your pet is showing other signs like lethargy or loss of appetite can help your veterinarian evaluate the situation.

If you suspect your pet swallowed something toxic or a foreign object, do not attempt to make them vomit or give a home remedy without veterinary advice.

If your dog or cat is vomiting or has diarrhea and you’re unsure whether emergency care is needed, call MarQueen Veterinary Specialty Group at 909-303-1700.

Few things worry a pet owner faster than a dog or cat who cannot keep food down, or who has repeated episodes of diarrhea.

Meet Mosely, lovingly described by his family as “the bestest little big guy.”

After Mosely underwent emergency surgery, Yvonne and Joel were told they might have only weeks or perhaps a few months left with him. Instead, they were blessed with another 22 precious months together.

During that time, Mosely became very special to our oncology caregivers and the entire MarQueen staff. It was an honor to care for him, support his family, and share in a journey filled with hope, courage, difficult decisions, and an extraordinary amount of love.
After saying goodbye to Mosely, his family shared a message we will carry with us:

“There is always hope, there is always strength for the fight, and love will always prevail…here and beyond.”

Yvonne and Joel hope Mosely’s memory can bring comfort, connection, and support to other families facing a pet’s cancer diagnosis, treatment, or loss. We are deeply grateful that they have allowed us to remember their sweet boy and share what he meant to so many people.

Please join us in honoring Mosely and sending love to his family. May you rest peacefully in the sunshine, sweet boy. You will always be remembered by your MarQueen family.
