  • 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. The best way to manage your grief is to be reassured that these reactions are normal and to let them run their natural course. 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.

  • The peach-faced lovebird is the largest and most commonly kept of the nine species of lovebirds. Lovebirds are incredibly inquisitive, playful, and possess a delightful, spirited sassiness. Although not generally very destructive, they do enjoy chewing. Young, single love birds bond closely with their owners and can be a wonderful, affectionate, and interactive family pet. A pair of lovebirds often bonds more strongly to each other even if they are the same sex. Young birds may be easier to tame and train than older, wild-caught, or colony- or parent-raised birds. After bringing your new bird home, you should have it examined by a veterinarian familiar with birds to help ensure that it is healthy. Like all other pet birds, lovebirds require annual, routine veterinary health check-ups.

  • 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 in North America are parasites called Paragonimus kellicotti that infect the lungs of cats after they have eaten an infected crayfish or rodents that have eaten infected crayfish. Eggs are then released by the parasite into the cat’s sputum to be coughed out or swallowed and released in the feces to continue the life cycle. Lung flukes can be found anywhere in North America but more commonly around the Mississippi River and Great Lakes. Infected cats can be symptom-free or may develop cough with sometimes bloody mucus, pneumonia, pneumothorax, lethargy and weakness. Diagnosis can include locating eggs of the parasite from feces or mucus from the lungs. X-rays can also reveal cysts in the lungs caused by the parasite. Treatment requires one of 2 commonly used anti-parasitic medications: Praziquantel or Fenbendazole. Although zoonotic, these parasites won’t transmit directly from cats to humans.
