Different areas of the brain control different functions, so this can manifest in a variety of ways, including: circling, termours, inability to walk, dragging limbs, changes to eye direction, behavioral changes, confusion, tremors or fitting. The brain is in a finite space within the skull, so bleeding within it tends to put pressure on the local brain tissue, affecting brain function. Intracranial (within the skull) bleeds can happen after a head injury or as a result of a bleeding tumour. The location of the bleed has a huge impact on any other symptoms that are seen The brain The lack of blood to the brain or lungs may result in collapse. If the circulation is compromised to the point where blood can no longer be delivered around the body, for example to the brain. If blood is lost from the circulation, the heart will have to beat extra fast to try to deliver what is left around the body. Therefore not all animals with internal bleeding appear pale or even have low numbers of red blood cells sometimes, they actually have a better colour! Luckily, a simple blood test can distinguish this kind of bleed. However, in the early stages after a bleed and before an animal looks pale, the spleen will often contract, releasing more red blood-cells into the circulation. Ongoing or large bleeds can result in the pet running out of red blood cells and looking ‘pale.’ Vets are good at spotting this. There are some common signs seen with any bleed: Pallor – paleness So what do we see on the outside when internal bleeding happens? A common example would be haemangiosarcoma on the spleen, which commonly leads to large amounts of blood loss into the abdomen. Tumours and the blood vessels within them are much more prone to bleeding than healthy vessels. Even without a history of trauma, these patients can bleed into the guts, internal spaces or the skin (causing bruising) until they become severely – often fatally – weakened. A common example is after the ingestion of anticoagulant rat poison. Further, in the event of the animal having a clotting disorder, this protective mechanism is completely removed. But in large bleeds, a clot is not always sufficient. Small bleeds would usually be self-limiting because the blood forms a protective clot. Pets may still bleed into spaces out of sight perhaps they may bleed into the brain after hitting the head, or from the spleen. For example, after a car accident, an absence of physical blood does not rule out bleeding.
