Canine protein-losing enteropathy is a syndrome: a group of conditions sharing the same outcome, excessive protein loss through the intestinal wall.<\/span><\/p>\n Albumin, the main protein in blood, maintains oncotic pressure and helps keep fluid within blood vessels. When albumin drops too low, fluid leaks into the abdomen, the chest, and under the skin.<\/span><\/p>\n In a healthy dog, protein circulates in the blood and is only released into the intestine in small, controlled amounts. In protein-losing enteropathy in dogs, the intestinal wall becomes abnormally permeable. Albumin and other plasma proteins leak from the bloodstream into the intestinal lumen faster than the liver can replace them.<\/span><\/p>\n The result is hypoalbuminemia in dogs, a persistently low blood albumin level that drives all the clinical signs of PLE.<\/span><\/p>\n Several intestinal diseases can cause excessive protein loss in dogs.\u00a0<\/span><\/p>\n IBD disease in dogs is the most common cause of PLE. Canine IBD is an immune-mediated condition that inflames the intestinal mucosa. Lymphoplasmacytic enteritis is the most frequently seen form. It damages the intestinal villi and increases gut wall permeability, allowing protein to leak into the intestine.<\/span><\/p>\n Predisposed breeds include Soft Coated Wheaten Terriers, <\/span>German Shepherds<\/span><\/a>, and Basenjis.<\/span><\/p>\n Lymphangiectasia in dogs is the dilation of the lymphatic vessels within the intestinal wall. Lymph, which is rich in proteins and fats, leaks into the intestinal lumen instead of being absorbed normally. Yorkshire Terriers are among the breeds most commonly affected.<\/span><\/p>\n A strict low-fat diet is essential for managing lymphangiectasia. Dietary fat stimulates lymph flow and directly worsens protein loss.<\/span><\/p>\n Intestinal lymphoma is the most common intestinal tumour in dogs and a significant cause of PLE. Other tumours and severe infections (e.g., parvovirus, hookworm) can also disrupt the gut wall, causing protein loss.<\/span><\/p>\n PLE symptoms in dogs develop gradually but can become severe. Watch for:<\/span><\/p>\n Hypoalbuminaemia in dogs disrupts far more than fluid balance. This type of protein enteropathy in dogs also causes:<\/span><\/p>\n These complications are why PLE is a potentially life-threatening condition, not just a digestive problem.<\/span><\/p>\n Diagnosis of PLE in dogs begins with blood tests. A low serum albumin (below 2.0 g\/dL) combined with low total protein points to significant protein loss. The next step is determining whether the loss is coming from the gut or the kidneys.<\/span><\/p>\n Faecal alpha-1 protease inhibitor (fA1PI) testing specifically measures protein lost through the GI tract. Abdominal ultrasound assesses intestinal wall changes, lymph node size, and fluid accumulation.<\/span><\/p>\n Endoscopy with intestinal biopsies is the gold standard. Histopathology of the biopsy tissue identifies IBD, lymphangiectasia, or lymphoma.<\/span><\/p>\n Treatment of PLE in dogs depends on the underlying cause, but dietary change and medical management work together in almost every case.<\/span><\/p>\n Diet is central to managing PLE disease in dogs regardless of the underlying cause.<\/span><\/p>\n IBD-related PLE is treated with immunosuppressives. <\/span>Prednisolone<\/span><\/a> is the first-line choice.<\/span> Dogs that do not respond may be stepped up to azathioprine, chlorambucil, or cyclosporine.<\/span><\/p>\n Cobalamin (vitamin B12) supplementation is often needed because chronic enteropathy can deplete B12 stores. Plasma or albumin infusions may be required acutely when albumin is critically low. Dogs at high risk of thromboembolism may require preventive anticoagulation.<\/span><\/p>\n Intestinal lymphoma requires <\/span>vet oncology consultation<\/span><\/a> and chemotherapy.<\/span><\/p>\n Managing dog PLE requires long-term commitment from both the vet team and the pet parent. Albumin levels are checked every four to eight weeks initially to assess the response to treatment.<\/span><\/p>\n Diet typically needs to be maintained lifelong. Dogs with IBD-related PLE can achieve remission and live well for years with the right management. Lymphangiectasia requires permanent dietary control but is compatible with a good quality of life in many cases.<\/span><\/p>\n Life expectancy depends heavily on the underlying cause.<\/span><\/p>\n Early diagnosis and a clear management plan designed by a <\/span>pet health expert<\/span><\/a> give any dog with PLE the best possible outcome.<\/span><\/p>\n PLE in dogs is manageable in many cases, but it demands a long-term veterinary partnership. No single medication or diet change is a quick fix. Consistent monitoring and a stable dietary routine make the biggest difference to outcomes.<\/span><\/p>\n If your dog is losing weight, developing a swollen belly, or has chronic unexplained diarrhoea, a Vetic vet can run the right tests and build a management plan. <\/span>Book a consultation at your <\/span>nearest pet clinic<\/span><\/a>.<\/span><\/p>\n PLE in dogs is not always curable, but it is often manageable. When IBD is the underlying cause, remission is achievable with medication and dietary change. Lymphangiectasia requires permanent dietary management. Intestinal lymphoma is managed rather than cured.<\/span><\/p>\n An ultra-low-fat diet is essential when the cause is lymphangiectasia. For IBD-related PLE, a hydrolysed protein or novel protein diet is recommended. Small, frequent meals reduce strain on the damaged gut.<\/span><\/p>\n Many PLE dogs live well with consistent management. Strict dietary control, regular monitoring, and appropriate medication allow most dogs to maintain a good quality of life.\u00a0<\/span><\/p>\n No. IBD is one of the most common causes of PLE, but PLE is a syndrome, not a specific disease. Intestinal lymphangiectasia, intestinal tumours, and severe infections can also cause PLE.<\/span><\/p>\n Collier, A.
