EdemaAn edema is a buildup of fluid in the body’s tissues, leading to Swelling. Edema can be localized or generalized and is often a sign of an underlying condition. are abnormal accumulations of fluid in a dog’s tissue, leading to swelling. These swellings often feel cool and are not associated with an elevated temperature.

Can Occur with the Following Diseases:

Basics and possible causes

Edema occurs when fluid leaks from the blood vessels into the surrounding tissue. This can be caused by a variety of factors that disrupt the balance between the forces that keep fluid in the vessels and those that push it out. Underlying causes include problems with blood pressure, the permeability of the vessel walls, and the function of organs such as the heart, liver, and kidneys.

Heart conditions, especially heart failure, can cause edemaAn edema is a buildup of fluid in the body's tissues, leading to Swelling. Edema can be localized or generalized and is often a sign of an underlying condition. because the heart can no longer pump blood effectively enough, leading to a backflow and increased pressure in the blood vessels. As a result, fluid is forced into the tissue. Liver diseases can also cause edemaAn edema is a buildup of fluid in the body's tissues, leading to Swelling. Edema can be localized or generalized and is often a sign of an underlying condition., as the liver produces proteins that maintain osmotic pressureOsmotic pressure is the pressure created by the diffusion of water across a semipermeable membrane, driven by differences in solute concentration on either side of the membrane. It plays an important role in the water and electrolyte balance of cells. in the blood. With kidney problems, the kidneys’ ability to remove excess fluid from the body may be impaired, which also leads to fluid accumulation.

Local factors can also cause edemaAn edema is a buildup of fluid in the body's tissues, leading to Swelling. Edema can be localized or generalized and is often a sign of an underlying condition., such as injuries, inflammatory conditions, or infections that increase the permeability of the vessel walls and promote fluid leakage. Allergic reactions can also play a role, as they triggerA trigger is a stimulus that elicits a specific reaction or state. In veterinary medicine, this can refer to emotional responses, such as fear or aggression, or medical conditions, such as seizures in dogs and cats. the release of histamine, which makes the capillary walls more permeable.
