Abstract: A study was conducted to find out the occurrence of lymphoproliferative disorders (LPDs) in dogs. A total of 66 dogs were diagnosed with LPDs out of 7,246 canine patients brought for treatment. The annual incidence rate of LPDs in dogs recorded as 0.91%. The animal details like breed, age and sex were recorded. Among the breeds, Mongrels were affected more than the pure breeds. The mean age of the dogs affected with LPDs is 4.32 years and it ranged from 2 months to 13.5 years. The LPDs were recorded more in males than females. The dogs affected with skin infections or mite infestations exhibited the signs of localized or generalized lymph node (LN) enlargements. The dogs affected with haemoprotozoan diseases revealed multiple LN enlargements, ecchymotic patches in the ventral abdomen and splenomegaly. The dogs affected with pyogranulomatous lymphadenitis revealed abscessation of entire LN and fever. The dogs affected with lymphoma exhibited multiple LN enlargements, splenomegaly, limb edema, corneal opacities, ascites and respiratory distress. The occurrence of LPDs was influenced by many intrinsic factors and the clinical signs in the dogs varied with the primary conditions.
