Internal Parasites in Dogs
En general, hay dos tipos de parásitos internos que afectan al perro. En primer lugar están los nematodos o gusanos redondos, de los cuales Toxocara canis (el gusano redondo intestinal más común) y Diarofilaria immitis (el gusano cardiaco) son los principales ejemplos. En segundo lugar tenemos los cestodos o gusanos planos, de los cuales Dipylidium caninum y las especies Taenia y Echinococcus son ejemplos importantes.

Grief is the normal and natural response to the loss of someone or something. It is a full body experience that includes physical, emotional, cognitive, social, and spiritual responses. Grieving takes time. Usually it gradually lessens in intensity over time, but if it doesn’t, then professional counseling may help.

Lotilaner is used to treat and prevent flea infestations and treat and control tick infestations in dogs and cats. After being administered to a pet, lotilaner is distributed throughout the body. When fleas or ticks bite the dog or cat, they are exposed to the drug and killed during their blood meal.

Lumbosacral disease, or cauda equina syndrome, is caused by the narrowing of the spinal canal and results in compression of the spinal nerve roots; pressure on the nerves that exit the spine cause the clinical signs. This pressure may be due to a narrowed spinal canal caused by arthritis, intervertebral disc herniation, an infection in the disc, trauma, congenital malformation, or a spinal tumor. Dogs with lumbosacral disease are in pain. If the clinical signs and radiographs suggest lumbosacral disease, advanced imaging such as MRI or CT is recommended to make a diagnosis. Treatment involves either conservative medical treatment or surgical intervention.

Lung flukes are parasitic worms (trematodes) that infect dogs’ lungs after they have eaten an infected crayfish or rodents that have eaten infected crayfish. Infected dogs can be symptom-free or may develop cough with sometimes bloody mucus, pneumonia, pneumothorax, lethargy and weakness.

Lung tumors are considered rare in cats and dogs. Many pets may not show symptoms at first, and a tumor may be found coincidentally. Depending on the type and stage of cancer, treatment may be possible; otherwise, symptomatic supportive care may be an alternative option.

There are many species of lungworm that can cause respiratory problems in dogs. Infection is acquired through either: ingestion of an intermediate host such as snails or slugs, ingestion of animals that have been infected by eating these animals or depending on the species, from an infected dog by contact with saliva, nasal discharge, or contaminated food and water bowls. Lungworms can be found throughout North America and the world with certain species seen in certain areas. Clincal signs can range from asymptomatic to tachypnea, coughing, sneezing, wheezing, respiratory distress or exercise intolerance. The degree of clinical signs is usually proportional to the strength of the dog’s immune system. Diagnosis involves history, physical exam, x-rays and organism identification through either baermann fecal examination or BAL/bronchoscopy. Treatment involves use of specific antiparasitic drugs for various lengths of time depending on type and severity of infection. Prognosis is good but re-infection can occur.
