Filed Under: Dogs, Horses, Poisoning

Oleander is an ornamental shrub that flowers in various colors including white, red, pink and violet. This plant is an evergreen perennial that flowers throughout the summer months. Originally a native plant of the Mediterranean, oleander is a very drought-tolerant ornamental. Oleander is now commonly found in warmer areas of the United States. It is often planted as an ornamental hedge along roads and gardens, although it is occasionally grown as a houseplant. The leaves are thick and leathery and vary from four to twelve inches in length.

Filed Under: Cats, Poisoning

The “Easter” or “trumpet lily”, whose scientific name is Lilium longiflorum, is a plant which is grown from bulbs. The plant itself has large, showy, funnel-formed flowers. The trumpet lily is popular at Easter, and for many it is symbolic of the resurrection of Christ. Sales of these lilies at Easter help to make them the fourth most popular selling potted plant in the United States. Unfortunately, these short-lived plants can shorten the life of your cat to days when eaten.

Avocado Poisoning in Horses

Filed Under: Horses, Diet & Nutrition, Poisoning

Raising avocados may be detrimental to the health of your horse. Avocado leaves, fruit, bark, and seeds all contain persin and an unidentified cardiac toxin. In lactating mares, persin produces a non-infectious mastitis (inflammation of the mammary glands), epithelial necrosis (skin cell death over the mammary glands) and agalactia (decrease in milk production). Occasionally gastritis and colic may occur.

Filed Under: Dogs, Diet & Nutrition, Poisoning

Want to share those macadamia nuts with your dog? Don’t, unless you want your dog staggering around the house appearing as if he is in a drunken stupor. A toxic dose of roasted macadamia nuts may be as little as one nut per kilogram of body weight in the dog.

Clinical signs begin two to twelve hours after ingestion. In addition to staggering, the dog may appear weak and depressed. Muscle tremors, vomiting, and an elevated temperature may also occur. Dogs are often painful in the joints, muscles and abdomen.

Grape and Raisin Toxicosis in the Dog

Filed Under: Dogs, Diet & Nutrition, Poisoning

Think grapes may be nutritionally good for your dog? Guess again! Raisins and grapes may be part of a nutritionally complete diet for people but can result in acute renal failure in susceptible dogs. The consumption of 11 to 30 grams of grapes per kilogram of body weight will result in clinical signs of toxicosis, and around 32 grams per kilogram will result in renal (kidney) damage. The number of raisins required to induce poisoning will be even less, requiring a dose of only 0.16 to 0.7 oz of raisins per kilogram of body weight resulting in poisoning.

Antifreeze Poisoning or Ethylene Glycol Toxicosis in Dogs and Cats

Filed Under: Dogs, Cats, Poisoning

Thinking about getting your car winterized this fall? Antifreeze is 95% ethylene glycol, (an important chemical used to prevent your car’s radiator from freezing or your windshield from icing) which is toxic to most animals although dogs, and to a lesser extent cats, appear to be primarily affected. Improper storage and handling of this chemical often leads to poisoning of pets since it has a sweet taste that may be attractive to animals. Most poisonings are accidental, but unfortunately, malicious poisonings may also occur.

Chocolate Toxicosis

Filed Under: Dogs, Cats, Poisoning

Think giving your pet chocolate is a suitable treat? Unfortunately, chocolate is toxic in dogs and many other species of animals. Most cases of poisoning involve dogs due to readily available sources of chocolate. In fact, consumption of chocolate is the 7th most common toxicosis in the dog. Dogs are infamous for getting into bags of chocolate morsels, a box of candy left on the coffee table, or the infamous Easter basket. Toxicities and death have also been reported in livestock when cocoa byproducts or mulch from cocoa-bean hulls were fed.
